<title>Introduction</title>
<p>Engineering doctoral students who pursue careers in academia will be required to teach courses; however, their PhD programs typically result in much less teaching experience compared to research experience. Most teaching experience occurs through graduate teaching assistantships, which may include training but involve a wide variety of roles. While some doctoral students seek additional instructional positions during their PhD programs, these are typically not required. Given this context, this study aims to understand engineering doctoral students&#x2019;expectations regarding the teaching requirements of being faculty.</p>
</sec>
<sec>
<title>Methods</title>
<p>To understand doctoral students&#x2019; expectations, 10 semi-structured interviews were conducted to address three sub-questions: (1) how participants&#x2019;teaching and mentoring philosophies have shifted throughout their PhD programs, (2) how important participants perceive teaching to be in academia, and (3) their expectations regarding classroom teaching as future faculty members. The interviews were conducted via Zoom, and the transcripts were coded and analyzed using NVivo.</p>
</sec>
<sec>
<title>Results</title>
<p>The analysis revealed that participants develop their instructional approaches through a combination of formal teaching assistantships, informal teaching and mentoring experiences, and interactions with faculty. Participants also expressed concerns about work&#x2013;life balance and the social responsibility associated with being an instructor.</p>
</sec>
<sec>
<title>Discussion</title>
<p>The findings emphasize the need for additional teaching experience and the expansion of development programs in engineering PhD programs, including resources on pedagogical principles. Future research may examine how these expectations evolve over time as doctoral students begin teaching.</p>

<title>Introduction</title>
<p>A doctoral degree in engineering does not have a singular purpose, instead opening a variety of pathways including career advancements in industry and academia (<xref ref-type="bibr" rid="ref46">Seo et al., 2021</xref>). A significant portion of engineering PhD students are expected to continue their academic careers as faculty, where they would essentially be required to teach courses [<xref ref-type="bibr" rid="ref35">National Center for Science and Engineering Statistics (NCSES), 2024</xref>]. However, in engineering PhD programs, the development of research skills is prioritized over development of teaching skills, as research productivity is valued more than teaching prowess when applying for faculty positions (<xref ref-type="bibr" rid="ref7">Buswell, 2020</xref>). Additionally, engineering doctoral students who intend to pursue an academic career after completing their PhD identify research as being one of the primary responsibilities in academia, and instructors feel that time spent teaching can interfere with the time they could spend working on research (<xref ref-type="bibr" rid="ref18">Garcia and Kittur, 2024</xref>; <xref ref-type="bibr" rid="ref33">Mena et al., 2013</xref>).</p>
<p>Most engineering doctoral students have teaching experience in the form of a teaching assistantship, with some of these teaching assistantships including forms of training (<xref ref-type="bibr" rid="ref18">Garcia and Kittur, 2024</xref>). <xref ref-type="bibr" rid="ref14">Fong et al. (2019)</xref> discusses the four most prominent types of teaching assistant (TA) training programs methods and goals, with some departments offering multiple training programs. Teaching assistant orientations are among the most common and typically provide information on department-level and/or university-level policies and resources (<xref ref-type="bibr" rid="ref14">Fong et al., 2019</xref>). However, when the only resource provided is a single orientation, TAs report a lack of preparation for teaching (<xref ref-type="bibr" rid="ref14">Fong et al., 2019</xref>). The other forms of preparation outlined by <xref ref-type="bibr" rid="ref14">Fong et al. (2019)</xref> are pedagogy classes, which may explore both practical and theoretical aspects of teaching from discipline-specific perspectives; mentoring programs, which provide opportunities for TAs to receive feedback from peers and experts; and certificate programs, more structured and multifaceted programs which typically require application of theory in classroom environments, consultations and evaluations based on teaching observations, and 20 real-time hours in TA training. Depending on the institution and PhD program, teaching assistantships vary from requiring multiple semesters to being optional. Additionally, the types of responsibilities associated with being a teaching assistant vary, leading to variances in sentiments and experiences with teaching (<xref ref-type="bibr" rid="ref19">G&#x00FC;ler et al., 2015</xref>; <xref ref-type="bibr" rid="ref18">Garcia and Kittur, 2024</xref>). <xref ref-type="bibr" rid="ref33">Mena et al. (2013)</xref> discuss the experiences of three engineering PhD students who served as course instructors as a part of their teaching assistantship, where the PhD students voluntarily sought additional teaching experiences. These TAs found difficulties in trying to balance their research and teaching responsibilities, and they did not have a faculty member to formally report to.</p>
<p>The multidisciplinary and multipurpose nature of an engineering doctoral program leads to a degree of inconsistency between different programs across different universities. This includes different requirements for teaching experiences for doctoral students. Lacking a universal protocol for training doctoral students who aspire to become future faculty members, there needs to be an effort made to better understand the resulting variety of expectations which these future instructors hold regarding their future teaching experiences.</p>
<p>This study is situated within the context of doctoral training in the United States, where research-intensive (R1) institutions emphasize research productivity while often providing limited formal preparation for teaching. Participants in this study were enrolled in U.S.-based engineering doctoral programs, primarily at R1 institutions, where teaching experiences are commonly obtained through teaching assistantships or limited instructor-of-record roles. As a result, the expectations examined in this paper reflect the structural and cultural norms of U.S. doctoral education and should be interpreted within this context.</p>

<title>Literature review</title>
<p>Regarding analyzing doctoral students as a whole or studying adjacent topics in engineering doctoral students, existing literature regarding the sentiments of engineering doctoral students for instruction in the future is incomplete (<xref ref-type="bibr" rid="ref54">Utecht and Tullous, 2009</xref>; <xref ref-type="bibr" rid="ref33">Mena et al., 2013</xref>). In addition, most of the existing literature discussing teacher expectations is about the expectations teachers have for their students rather than the expectations teachers have for instruction and the general teaching experience (<xref ref-type="bibr" rid="ref22">Johnston et al., 2019</xref>). In this section, there will be a discussion of the literature under three subsections, the development of teaching and mentoring philosophy in engineering PhD students, how engineering PhD students perceive the value of teaching in academia in relationship to the other aspects of academia, and the expectations of in-classroom experiences as instructors.</p>
<sec id="sec3">
<label>2.1</label>
<title>Development of teaching and mentoring philosophy</title>
<p>As mentioned in the previous section, <xref ref-type="bibr" rid="ref14">Fong et al. (2019)</xref> finds that the pedagogy course showed greater benefit to TAs, though the pedagogy course and the teaching mid-semester feedback both showed greater increases in reflective teaching efficacy and belief that teaching influences learning (<xref ref-type="bibr" rid="ref14">Fong et al., 2019</xref>; <xref ref-type="bibr" rid="ref38">Pollard, 2021</xref>). <xref ref-type="bibr" rid="ref52">Torre Ayala (2013)</xref> describes five categories of conceptions of teaching engineering: delivering knowledge, helping understand and apply concepts, motivating students, helping students learn how to approach problems, and preparing to make students socially conscious. The study identifies four categories of experiences which shaped future engineering professors&#x2019; conception of teaching engineering: observing professors, their own student experience, talking about teaching, and their own teaching experience. This contrasts with the simple, traditional saying of &#x201C;teaching as they were taught&#x201D;, as identified and countered by Oleson and Hora (2014) and <xref ref-type="bibr" rid="ref38">Pollard (2021)</xref>. This observation aligns with work in the ASEE community emphasizing that teaching identity develops through reflective practice and instructional experiences rather than passive replication of prior instruction (<xref ref-type="bibr" rid="ref21">Huang et al., 2005</xref>; <xref ref-type="bibr" rid="ref53">Turns et al., 2014</xref>; <xref ref-type="bibr" rid="ref56">Wankat and Oreovicz, 2015</xref>). However, the study does not cover how prior teaching context influences the conceptions of learning held by future engineering professors, nor does it cover the changes in the engineering education environment after publication, such as the surge of adoption of distance learning (<xref ref-type="bibr" rid="ref52">Torre Ayala, 2013</xref>). Experiences as TAs and as instructors give doctoral students the opportunity to test and adjust their teaching philosophies in practical settings, solidifying the aspects of their teaching philosophies which work and shifting those which do not (<xref ref-type="bibr" rid="ref38">Pollard, 2021</xref>).</p>
<p><xref ref-type="bibr" rid="ref52">Torre Ayala (2013)</xref> identifies that future engineering professors show an interest in teaching students to consider the social impact of engineering, while lacking the requisite preparation to teach this. This feeling of lacking preparation is reflected in <xref ref-type="bibr" rid="ref11">de Lima et al. (2024)</xref>, which describe how engineering doctoral teaching assistants can make learning spaces more equitable and accessible for students. The doctoral teaching assistants expressed a need for additional training in regard to encountering discrimination in the classroom, as they generally rated the importance of inclusivity in engineering education above their capability to influence inclusivity (<xref ref-type="bibr" rid="ref11">de Lima et al., 2024</xref>).</p>
<p><xref ref-type="bibr" rid="ref57">Watson and Strong (2013)</xref> examined the different educational philosophies held by graduate students at the Georgia Institute of Technology, finding that while progressivism, or the practice of integrating real-world experiences with classroom study, was endorsed by the Educational Philosophy Inventory, the philosophies which they experienced as students were more often reflected in their current and future teaching practices (<xref ref-type="bibr" rid="ref57">Watson and Strong, 2013</xref>). As a result, <xref ref-type="bibr" rid="ref57">Watson and Strong (2013)</xref> suggest that interventions should be considered to teach graduate students about various teaching philosophies and their classroom implications. In addition, they found a discrepancy in the teaching philosophies which were reported as being in use by graduate students and the teaching practice which were planned to be used in future teaching practices, which <xref ref-type="bibr" rid="ref38">Pollard (2021)</xref> suggests that these discrepancies are due to factors such as time constraints and the decreased priority of teaching-related tasks compared to research-related tasks.</p>
<p>Through the mentorship experiences granted by an engineering PhD program, students are able to connect with faculty both academically and personally (<xref ref-type="bibr" rid="ref1">Ambler et al., 2016</xref>). A mentor can help minimize the difficulties and barriers a student may face through the research process, as well as develop personal connections which can evolve into friendships (Mirabelli et al., 2020; <xref ref-type="bibr" rid="ref1">Ambler et al., 2016</xref>). However, formal mentoring relationships regarding teaching are not part of engineering doctoral curriculums (Stice et al., 2000, as cited in <xref ref-type="bibr" rid="ref7">Buswell, 2020</xref>). Additionally, in being a mentor, academics have greater opportunities to self-reflect and encounter new ways of thinking through interactions with mentees, though research relating to the effects of being a mentor is sparce (<xref ref-type="bibr" rid="ref1">Ambler et al., 2016</xref>).</p>
<p>The experiences of being a mentor and being a mentee provide engineering PhD students with the space to reflect on their conceptions of teaching. While parts of the teaching philosophies developed by engineering PhD students are formed through their experiences as students, additional training and professional development programs can help shape their philosophies, though these resources may not always be readily accessible. Additionally, these teaching philosophies may not be necessarily congruent with their teaching in practice due to factors such as time constraints and the general decreased priority of teaching-related tasks compared to research related tasks. More details regarding the perceived importance of teaching are found in the next section.</p>
</sec>
<sec id="sec4">
<label>2.2</label>
<title>Perceived importance of teaching in academia</title>
<p>Research regarding the importance of teaching in academia typically describes this through the perspective of balancing teaching and research activities (<xref ref-type="bibr" rid="ref40">Robert and Carlsen, 2017</xref>). While professors often personally value teaching as highly as research, they usually direct their and their departments&#x2019; priorities towards research (<xref ref-type="bibr" rid="ref44">Savkar and Lokere, 2010</xref>). However, <xref ref-type="bibr" rid="ref8">Cadez et al. (2015)</xref> found that research productivity is not related to teaching quality, and that high quality research is positively related to teaching quality. However, the research orientation of a school as a whole is negatively related to teaching quality (<xref ref-type="bibr" rid="ref8">Cadez et al., 2015</xref>).</p>
<p><xref ref-type="bibr" rid="ref34">Miskioglu et al. (2020)</xref> finds that the number of classes taught per mechanical engineering faculty member, both tenure-track and tenured, at R1 institutions is between 1&#x2013;4 classes per year, much lower than those at more teaching-focused institutions. The tenure-track faculty also generally indicated that they felt that teaching load had a lower likelihood to affect. Additionally, faculty at R1 institutions indicated that they were typically expected to have more than 10 journal publications by the time they applied for tenure, whereas faculty at non-R1 institutions state that they were expected to have fewer than 10 journal publications. Similarly, <xref ref-type="bibr" rid="ref30">Lane et al. (2019)</xref> describes how doctoral students perceived a stigma which discouraged exploring teaching experiences. The discrepancy in value between research and non-research work leads to the perception that a large investment of time in non-research work would lead to falling short of promotion standards for faculty (<xref ref-type="bibr" rid="ref49">Terosky et al., 2014</xref>). Similar concerns have been raised in ASEE scholarship highlighting how doctoral students often receive limited structured preparation for teaching despite future faculty expectations (<xref ref-type="bibr" rid="ref13">Felder and Brent, 2024</xref>; <xref ref-type="bibr" rid="ref24">Kajfez and Matusovich, 2020</xref>).</p>
<p>The different perceptions graduate TAs hold regarding the importance of teaching in their careers can impact their approaches to interactions with students, as suggested by <xref ref-type="bibr" rid="ref24">Kajfez and Matusovich (2020)</xref>. Graduate TAs who strongly identify with teaching have more applicable experience with instruction, while those who weakly identify with teaching have more ability to connect course material with industry experiences and develop coursework to more closely align with real-world experiences (<xref ref-type="bibr" rid="ref24">Kajfez and Matusovich, 2020</xref>). These experiences as TAs work as peripheral participation in teaching, shaping the experiences and trajectories of engineering PhD students through the more critical observation of teaching and studying enabled through the role (<xref ref-type="bibr" rid="ref38">Pollard, 2021</xref>).</p>
<p>While individual work outcomes do not typically have detrimental effects on teaching quality, the ways departments work within a university do affect teaching quality, such as requiring more journal publications to achieve tenure. This leads to a greater time investment in research which may detract from maximizing the effectiveness of teaching, both outside of the classroom as well as within it. The next section will discuss the expectations of PhD students for the in-class experience.</p>
</sec>
<sec id="sec5">
<label>2.3</label>
<title>Expectations for in-class experiences</title>
<p><xref ref-type="bibr" rid="ref28">Kumar (2021)</xref> details the perspective of graduate teaching assistants regarding engineering education in distance teaching courses. Given the relative novelty of the distance teaching model in comparison to the more traditional, in-person formats, student feedback and communication were imperative to ensure the efficacy of the instructional process. <xref ref-type="bibr" rid="ref28">Kumar (2021)</xref> identifies a variety of challenges of graduate teaching assistants prior to beginning to teach online: technology issues, communication gaps between TA and students/TA and instructor, anxieties related to teaching online for the first time or lack of expertise in assigned area, and lack of clarity relating to TA expectations and duties. Some of these concerns align with the concerns of graduate TAs in in-person classrooms, while others are unique to the format of online teaching. The experiences of being a graduate teaching assistant are known to affect the self-efficacy of graduate students regarding teaching, however the effects of being a graduate teaching assistant in an online classroom on future teaching is less known (<xref ref-type="bibr" rid="ref28">Kumar, 2021</xref>; <xref ref-type="bibr" rid="ref52">Torre Ayala, 2013</xref>).</p>
<p><xref ref-type="bibr" rid="ref12">Di Benedetti et al. (2022)</xref> found that there was a disconnect between the roles and personal identities of TAs serving as teachers. TAs did not feel empowered to make decisions and influence their students how the TAs feel fit but instead fell back on the opinions of the instructor leading the class, seeking approval over autonomy even when unnecessary (<xref ref-type="bibr" rid="ref12">Di Benedetti et al., 2022</xref>). While TA orientation programs can develop confidence and self-efficacy, the specific content and focus of these programs impact the outcomes in the TAs (<xref ref-type="bibr" rid="ref42">Rosse-Richards et al., 2013</xref>; <xref ref-type="bibr" rid="ref10">Dawe et al., 2017</xref>; <xref ref-type="bibr" rid="ref59">Wright et al., 2019</xref>). Engineering education research has similarly documented how reflective teaching experiences and structured preparation influence TA identity and instructional confidence (<xref ref-type="bibr" rid="ref21">Huang et al., 2005</xref>; <xref ref-type="bibr" rid="ref5">Borrego et al., 2010</xref>; <xref ref-type="bibr" rid="ref53">Turns et al., 2014</xref>).</p>
<p>Once entering teaching roles, new faculty describe feeling unprepared to adequately serve their teaching roles, though the availability and quality of teaching training can vary in every university (<xref ref-type="bibr" rid="ref7">Buswell, 2020</xref>). <xref ref-type="bibr" rid="ref7">Buswell (2020)</xref> recommends a greater investment of resources in R1 institutions towards existing infrastructure supporting teaching and preparation to teach and suggests that additional teaching opportunities and mentorship may be suitable to better position graduate students in the job market. Similarly, <xref ref-type="bibr" rid="ref4">Bonner et al. (2020)</xref> recommends intensive and required doctoral teaching seminars to sufficiently teach course design, as students who discount the importance of teaching or believe they have the necessary teaching skills without prior experience may opt out of such a course. In contrast, <xref ref-type="bibr" rid="ref29">Lam et al. (2024)</xref> finds that participants in the Future Faculty Teaching Fellowship, a Preparing Future Faculty program, rated teaching at their home institution to be generally more helpful compared to pedagogy coursework, suggesting that increased teaching opportunities may be more helpful for graduate students.</p>
<p><xref ref-type="bibr" rid="ref20">Hassel and Ridout (2018)</xref> describes the expectations instructors have of students, where instructors expected their students to positively engage with the lecture and regularly attend the course. Additionally, students tended to agree with these expectations, of positive engagement and regular attendance. The importance of this positive engagement is reflected by <xref ref-type="bibr" rid="ref16">Freeman et al. (2014)</xref>, which finds that active learning increases examination performance in STEM courses and shows a significantly lower failure rate than lecturing. This emphasis on active engagement is well established in engineering education literature, particularly within ASEE and IEEE communities examining active learning and challenge-based instruction (<xref ref-type="bibr" rid="ref39">Prince, 2004</xref>; <xref ref-type="bibr" rid="ref41">Roselli and Brophy, 2006</xref>). However, <xref ref-type="bibr" rid="ref15">Fraser and Killen (2003)</xref> find that instructors expected their students to be more independent and self-driven while still attending lectures, while students disagreed by generally undervaluing the importance of lecture attendance.</p>
<p>TAs can feel a lack of empowerment to make their own decisions regarding a classroom situation, and there are a variety of forms an engineering course can take, and these forms have shared and unique complications, such as the differing social dynamics within in-person and online teaching. In addition, the expectations of instructors and their relationship with student expectations are important regarding effective learning. These factors suggest that a better understanding of the perspective of engineering doctoral students regarding teaching before they transition into faculty roles may be necessary to provide guidance to provide better experiences to students. To achieve this understanding, a qualitative analysis of semi-structured interviews was chosen for data collection in this study.</p>

<title>Conceptual framework</title>
<p>This study is guided by a conceptual framework that integrates perspectives on teaching and mentoring identity formation, social learning through communities of practice, and self-efficacy development. Together, these perspectives provide a lens for understanding how engineering doctoral students construct expectations about teaching and mentoring during their doctoral training.</p>
<p>Teaching and mentoring identity formation literature emphasizes that instructional identities develop over time through reflection, practice, and interaction with institutional norms rather than through simple replication of prior experiences. From a communities of practice perspective, doctoral students engage in peripheral participation in teaching and mentoring through roles such as teaching assistants, informal mentors, and observers of faculty practice, gradually negotiating their identities as future educators. Additionally, self-efficacy theory highlights how mastery experiences, vicarious learning, and social persuasion contribute to doctoral students&#x2019; confidence in teaching and mentoring roles.</p>
<p>While these perspectives inform interpretation, the study remains inductive in design, allowing themes to emerge from participants&#x2019; narratives rather than applying a predetermined analytical framework.</p>

<title>Methodology</title>
<p>This study was part of a larger investigation into engineering doctoral students&#x2019; perceptions of teaching in higher education through a qualitative research approach. This approach was taken to better capture details regarding participants&#x2019; experiences and perceptions regarding education in engineering academia.</p>
<sec id="sec8">
<label>3.1</label>
<title>Data collection</title>
<p>Potential participants were identified and reached out to through email found on student directories. An initial screening survey was designed and administered to potential participants to collect data on career preferences, teaching experiences as a TA or as an instructor, racial/ethnic background, and engineering department. Only responses from doctoral students who intended to continue a career in academia completing their program were invited to participate in the interview. Semi-structured interviews were conducted to collect data, utilizing improvised questions to probe additional information from pre-planned questions. This format enhanced the data collection process through this flexibility (<xref ref-type="bibr" rid="ref9">Creswell and Poth, 2016</xref>; <xref ref-type="bibr" rid="ref43">Ruslin et al., 2022</xref>; <xref ref-type="bibr" rid="ref26">Kittur and Tuti, 2024</xref>). The planned duration for each interview was between 45 and 60&#x202F;min. This duration was decided to minimize fatigue for the participants while allowing time for participants to reflect on their experiences (<xref ref-type="bibr" rid="ref43">Ruslin et al., 2022</xref>; <xref ref-type="bibr" rid="ref17">Galletta and Cross, 2013</xref>).</p>
<p>Doctoral students from more than 20&#x202F;U.S.-based R1 institutions were contacted through publicly available departmental directories. Twenty-three students completed an initial screening survey, all of whom met the inclusion criterion of intending to pursue academic faculty careers. Fourteen students agreed to participate in interviews; however, data collection was concluded after ten interviews due to the achievement of thematic saturation, as no new codes or themes were emerging in later interviews. Participants were drawn from multiple institutions and engineering disciplines, and none had prior relationships with the researchers.</p>
</sec>
<sec id="sec9">
<label>3.2</label>
<title>Interview procedure</title>
<p>Interviews were conducted through Audio-only Zoom calls to record interviews with the participants. The audio recordings were digitally transcribed automatically, allowing for the focus of the interview to shift to easing the conversation&#x2019;s flow, asking follow-up questions, and improving rapport with the participant, key elements in completing an effective semi-structured interview (<xref ref-type="bibr" rid="ref32">Mannan and Afni, 2020</xref>). An interview guide was designed with a series of open-ended questions and closed-ended questions, with a significant portion of time dedicated to asking additional follow-up questions to have a more comprehensive record of the participants&#x2019; perspectives and experiences. Ten interviews were conducted, which were recorded with the consent of each participant. An incentive of $20 Amazon gift cards was offered to each participant.</p>
<p>To improve readability of interview excerpts, minor grammatical corrections were made using generative AI. These edits were limited to removing verbal disfluencies (e.g., repeated words, filler phrases, incomplete sentences) and correcting basic grammar. No paraphrasing, rewording, or alteration of meaning was performed. All edited excerpts were manually verified against the original transcripts by the authors to ensure fidelity to participants&#x2019; intended expressions. Please refer to <xref ref-type="supplementary-material" rid="SM1">Appendix A</xref> for examples of raw vs. edited interview excerpts.</p>
</sec>
<sec id="sec10">
<label>3.3</label>
<title>Inductive coding</title>
<p>To ensure that patterns and themes could emerge directly from participants&#x2019; responses, an inductive coding approach was utilized to analyze the transcripts (<xref ref-type="bibr" rid="ref36">Neuendorf, 2018</xref>). The interviews were coded through NVivo, eliminating redundant codes through iterative review. Initial coding began with open, descriptive codes closely aligned with participants&#x2019; language. Through iterative rounds of coding and constant comparison across transcripts, these initial codes were refined, merged, or subdivided into more analytically meaningful categories. Broad codes such as Teaching Philosophy and Mentoring Philosophy were subsequently differentiated into sub-codes capturing specific dimensions (e.g., approachability, motivation, autonomy, boundaries). This iterative process continued until a stable codebook was established and no new codes emerged. A comprehensive codebook was developed, detailing each code and its description. This codebook was subsequently used to analyze the remaining transcripts, with new codes being added and existing codes being refined as more transcripts were analyzed. The codes were then categorized into themes to answer the research question. Although data analysis was inductive, interpretation of the findings was informed by existing theoretical perspectives on identity formation, social learning, and self-efficacy to contextualize participants&#x2019; experiences within the broader engineering education literature.</p>

<title>Question 1: How have student experiences in PhD programs shaped student teaching and mentoring philosophy?</title>
<p>The ways that the participants think about teaching and mentoring did not exist in a vacuum but rather were shaped by their past formal and informal experiences as students, mentees, teachers, and mentors. These philosophies were not singular, monolithic ideals, but rather ideas that shifted and formed with different experiences.</p>
<sec id="sec13">
<label>4.1.1</label>
<title>Teaching philosophy</title>
<p>The participants generally focused their teaching philosophies, or beliefs and methods regarding teaching, on one or two factors of approachability, influence, and motivation.</p>
<sec id="sec14">
<label>4.1.1.1</label>
<title>Approachability</title>
<p>A common pattern emerged in responses where multiple participants would mention specifically trying to decrease the pressure placed on students for asking questions and generally trying to present themselves as approachable. Amy describes a focus on maintaining consistent interactions with students, potentially in a sense where a class would be shaped in a way to better fit this ideal, with the goal of making sure students feel empowered to look for support if they feel it is necessary. While Bri&#x2019;s philosophy also places an importance on empowering students to find support, they do not express a focus on shaping their class to encourage student-teacher interaction. Below are the excerpts from Amy and Bri&#x2019;s interviews where they talk about the importance of approachability.</p>
<disp-quote>
<p>&#x201C;There&#x2019;s no shame in asking questions. I want [students] to have lots of interaction with me. Walk through hard problems together, we are gonna [going to] learn all of the skills together and then we are gonna [going to] test those skills by either doing projects or homework or maybe an occasional quiz or test. But make sure that we are all learning kind of at the same pace and that nobody is left out to dry. No one&#x2019;s left behind. Making sure that I am really accessible and that students can get the help they need.&#x201D; (Amy)</p>
</disp-quote>
<disp-quote>
<p>&#x201C;As a teacher, you should always be able to explain your students why and that you should like offer that [explanations] to them, as you are teaching them that you should be approachable. That no question is a dumb question.&#x201D; (Bri)</p>

<title>Influence</title>
<p>Instructors interact with students from a position of authority. As a result, instructors may have the ability to adjust the behaviors or values of students regarding their approach to education. Both Tony and Austin&#x2019;s philosophies engage the lasting impacts of their instruction on students. Austin specifically discusses the ways in which different forms of communication through personality may impact on how students perceive the experience of learning engineering topics. However, Tony focuses more on the effects that class design and formatting can affect the impact of a class, specifically through the encouragement of interactions with and between students. Despite the difference in methods, they both explicitly agree on ensuring that students receive a comprehensive, quality education.</p>
<disp-quote>
<p>&#x201C;As a teacher, I think it is not just your responsibility to teach some relationships and sentences, dates, times. I think that your personality matters. The way you talk matters. I think that specifically younger generations take influence from their instructors, so details also matter there&#x2026; I want to be a good role model for younger people, but at the same time, your main job is to basically be able to give students a high-quality class that all of the necessary, important parts of that [class/topic] is covered.&#x201D; (Austin)</p>
</disp-quote>
<disp-quote>
<p>&#x201C;I think it&#x2019;s [my teaching philosophy is] putting in the effort, designing the class to be active, engaging, functional, having those learning objectives, but beyond that, making them useful learning objectives. What are the students going to take with them for the rest of their life? Being engaging, forging personal connections with the students, having the students work with each other, and making sure that at the end of the day, every student has had the opportunity to reach those learning objectives.&#x201D; (Tony)</p>

<sec id="sec16">
<label>4.1.1.3</label>
<title>Motivation</title>
<p>In addition to discussing their role in influencing students, the participants also placed a focus on managing motivation in students. Madison and Calvin describe two different methods of managing and fostering motivation in students. Madison, who has experience as an instructor for graduate students, prioritizes generating intrigue and curiosity from their students, whereas Calvin, who&#x2019;s prior experience as an instructor was with undergraduate students, prioritizes utilizing difficulty to push students to learn a topic at a deeper level.</p>
<disp-quote>
<p>&#x201C;I think I want people to be curious about things, like I&#x2019;m less about trying to teach people every piece of information, and more of it, just like. &#x201C;You think it&#x2019;s cool. I think it&#x2019;s cool, too.&#x201D; You can learn more about that. And I do not know having people like. I like for students to be very hands-on. Exploring. I mean, basically doing what you do in a PhD like, you know, you find something you love. And you get really into it. So I [kind of want to] inspire that like more than just. Like, more than just rote knowledge.&#x201D; (Madison)</p>
</disp-quote>
<disp-quote>
<p>&#x201C;I have the philosophy of. If I&#x2019;m I want to give a student a challenge that is. It is almost unreasonable for them to be able to accomplish. And then I want to be kind. When I go to grade it. I think failure is a part of the learning process&#x2026; I do know that part of the process of learning requires that you challenge yourself beyond what you can already do right. And part of that process is going to involve you making mistakes and failing sometimes. And so, if I can foster that feeling. Of. It&#x2019;s okay for me to mess up here. But this is something that&#x2019;s really challenging, that I have to put a lot of focus and effort into. That&#x2019;s an environment that I want to foster. So, if I can do that in my lectures, I will try to do that. I&#x2019;ll put pressure on students to try to answer questions or try to figure stuff out.&#x201D; (Calvin)</p>

<p>To synthesize the findings related to the development of teaching philosophy, <xref ref-type="fig" rid="fig1">Figure 1</xref> presents a conceptual model illustrating how engineering doctoral students construct their teaching philosophies. Rather than emerging solely from how participants were taught, teaching philosophy is shaped through a combination of formal teaching experiences (e.g., teaching assistantships and instructor-of-record roles), informal instructional experiences, peer interactions, and observation of faculty teaching practices. These influences collectively inform participants&#x2019; instructional approaches, expectations of students, classroom practices, and perceptions of the social responsibility associated with teaching. The figure is grounded in inductive themes derived from the interview data and provides an integrative overview of how teaching philosophies develop during doctoral training.</p>

<title>Mentoring philosophy</title>
<p>In contrast to teaching philosophies, mentoring philosophies tended to be more diverse and dependent on individual experiences. However, the generation of these philosophies often originated from situations where the participants were both mentors and mentees, even in both official and unofficial settings.</p>
<sec id="sec18">
<label>4.1.2.1</label>
<title>Approaches as mentors</title>
<p>Aaron describes how they would prefer to balance an amount of independence and intervention as a mentor, working to identify the situations where these approaches would be best for their mentee. This balance seeks to maximize the development of independence and skills by a mentee while minimizing any risks that could be imposed from this independence.</p>
<disp-quote>
<p>&#x201C;When you have a mentee, your job as the mentor is to make sure you know the difference between when your mentee is just falling down a little hill or when they&#x2019;re falling down a canyon, right? Because you can let them fall down a little hill. That&#x2019;s good for them. Like, getting them to fall down a little hill, you know, yeah, it might get a little rough and tumbly, but at the end of the day, they&#x2019;ll be able to pick themselves back up. You know, they&#x2019;ll climb up with relative ease. Now, if you let them fall down a canyon, there&#x2019;s no way they&#x2019;re getting back up, right? They can&#x2019;t. It&#x2019;s so steep, there are so many rocks, they&#x2019;re never going to be able to get back up. And so, it&#x2019;s about being able to know the difference there. Because yes, as a mentor, sometimes you do need to let them kind of learn on their own. But it&#x2019;s knowing when you need to step in, as the mentor, to guide them away from the cliffs, a lot of the time.&#x201D; (Aaron)</p>
</disp-quote>
<p>Imane discusses her experiences with being a mentor as an undergraduate student for other undergraduate students as well as a graduate student. As she gained more experience in mentoring, Imane developed an understanding of her mentees and how to communicate with them effectively.</p>
<disp-quote>
<p>&#x201C;I was also a mentor for undergraduate students in my lab, and I was a student assistant for one of my courses before I got into grad school. Being a student assistant basically meant going around, answering questions, and helping explain concepts for a class I had already taken. I didn&#x2019;t have much administrative power, so I was basically just another student who knew a bit more than others and could help explain things. Being a mentor in my lab made me realize that I needed to plan things ahead and think about what I was actually trying to teach the student, instead of going in without a clear idea. I also realized that I needed to consider my own ability level and skill set compared to the student&#x2019;s, so I wouldn&#x2019;t confuse them or leave them behind in what I was trying to do.&#x201D; (Imane)</p>

<title>Experiences as mentees</title>
<p>In addition to the official mentor-mentee relationships, unofficial mentor-mentee dynamics facilitate more casual types of interactions and advice, such as the general advice Ray mentions. However, unlike more official, designated mentor-mentee relationships, these unofficial relationships allow for more social flexibility to feel comfortable in seeking help for smaller tasks rather than focusing on approaching a specific goal.</p>
<disp-quote>
<p>&#x201C;There are just peers of mine in the lab, specifically those that were grad students before I got here. So with more experience. And although we&#x2019;ve never like claimed a mentor-mentee relationship, like I will literally go to these people all the time, like ask them to like proofread emails, for example, or like how should I approach this problem that I&#x2019;m having or like what journal should I submit to? And, you know, like things that like the general advice that you ask your friends.&#x201D; (Ray)</p>
</disp-quote>
<p>As PhD students have varying levels of research experience, some may be more reliant on mentorship to learn to navigate the research process, as Madison describes.</p>
<disp-quote>
<p>&#x201C;My advisor is a really good mentor. One of the things I really appreciate is that. Like the students she takes on. Typically, we do not have. Like my lab mates, and I do not have like super strong research. Backgrounds like, I know, a lot of advisors will just take on students who know how to do research and just have them do research versus my advisor is very like. He wants to train us to do research. He wants it to be accessible. And I think that&#x2019;s really. Impressive and like she wants us to. Do the whole design of everything from the beginning. And that&#x2019;s slower. It means that we aren&#x2019;t publishing as fast as some other labs. That means that ultimately, we are better. So, I think I&#x2019;m like grabbing cases of mentoring that I like from other people. I think she&#x2019;s a fantastic mentor.&#x201D; (Madison)</p>

<title>Experiences in non-academic mentee-mentor dynamics</title>
<p>Bri&#x2019;s experience as a mentor in her religious group helped her better define her own mentorship philosophy that approaches mentees in a more holistic manner, viewing their mentee&#x2019;s experiences in a general sense rather than focusing on a specific area.</p>
<disp-quote>
<p>&#x201C;My more formal mentoring has been through Christian groups that I&#x2019;ve been a part of, as an undergrad and as a graduate student, through what we call discipleship. There&#x2019;s a much more religious and spiritual aspect to that compared to what I would do in lab, obviously. But I feel like that has taught me how to, just, when you disciple someone, you do not just mentor them spiritually. We do not just talk about what they read in their Bible that week. It&#x2019;s about their whole life, right? You have to be open to hearing about how they did on their test, and all of these other things that make up someone&#x2019;s life. And not only open to that, but you have to actually want to hear about it. You have to want to support them in that. I feel like that&#x2019;s an attitude I would want to bring into lab mentoring. When I do that, I do not think I&#x2019;d ever want it to be just about science. I do not think that&#x2019;s how you build a healthy mentor and mentee relationship.&#x201D; (Bri)</p>
</disp-quote>
<p>To synthesize the findings related to the development of mentoring philosophy, <xref ref-type="fig" rid="fig2">Figure 2</xref> presents a conceptual model illustrating how engineering doctoral students construct their mentoring philosophies. Mentoring philosophy develops through participants&#x2019; experiences both as mentees and mentors, including formal advisor relationships, peer mentoring, informal mentoring within research groups, and non-academic mentoring contexts. These experiences shape participants&#x2019; approaches to mentoring, including how they balance autonomy and guidance, define mentoring boundaries, communicate expectations, and view their responsibilities toward mentees. This figure is grounded in inductive themes from the interview data and offers an integrative representation of the processes through which mentoring philosophies are formed during doctoral training.</p>

<title>Question 2: How do student experiences in PhD programs affect how PhD students value the importance of teaching in academia?</title>
<p>To understand how the different experiences of the participants led to differing expectations in teaching expectations, it is important to identify and understand how they may value teaching differently based on those experiences.</p>
<sec id="sec22">
<label>4.2.1</label>
<title>Time and effort requirements for teaching</title>
<p>Given the diverse requirements of faculty in academia, ranging from research to institutional service, the amount of time and effort that can be dedicated to teaching has to be balanced with the rest of the requirements of faculty members responsibilities. Generally, expectations and concerns the participants expressed about the time requirements for teaching were related to their observations of professors they worked with or been taught by.</p>
<p>The participants expressed mixed sentiments about their expectations for the amount of time they would need to spend on their classes and working in general. This is reflected in the differences in their experiences, where those who had experience leading a full class as a primary instructor were more pessimistic about their expectations for the amount of time and attention they need to dedicate to their classes, whereas those who had a more limited experience, such as spending time as a TA for a class generally were more optimistic about how much time they would need to dedicate to teaching. Below are the excerpts from Amy and David.</p>
<disp-quote>
<p>&#x201C;I think that you just have to be really careful with how you manage your time, and what responsibilities you take on. Because workload balance is really important, and I&#x2019;ve seen professors get eaten alive by work and some that really excel while working. But making sure that work doesn&#x2019;t take over is kind of the most important thing. Yeah, like, being (having) a good relationship with work. Like, I&#x2019;m not going to be a professor who works around the clock every single day, you know. I&#x2019;m not gonna work 80-hour weeks. That&#x2019;s just not, that&#x2019;s not a sustainable thing for me or my students.&#x201D; (Amy)</p>
</disp-quote>
<disp-quote>
<p>&#x201C;Hmm. I don&#x2019;t necessarily have any concerns [regarding work life balance]. Because again, I&#x2019;ve seen my professors over the years and some that have been a very helpful in my in classes and then my overall educational career who they seem to be, have a good work life to actually have a good work life balance whether it be and I think if that just comes with being a professor and kind of not being your own boss.&#x201D;(David)</p>
</disp-quote>
<p>In the below excerpt, Ray describes how working as a TA and working as a tutor differ in how they affect his motivation and sentiments surrounding teaching. At first, when he was mostly interfacing with teaching from the perspective of one-to-one tutoring, Ray enjoyed the connections he made with his students. However, once he began being a TA, Ray realized and began to worry about the workload he associated with teaching engineering at the university level.</p>
<disp-quote>
<p>&#x201C;As a TA, because I&#x2019;m like the one like creating the content and like helping deliver it, it&#x2019;s like, obviously I&#x2019;m doing the best I can, right? But there&#x2019;s like more of them and they&#x2019;re not all getting at the same speed. And I wouldn&#x2019;t say TA makes me like less strong to teaching, but tutoring definitely really encouraged me to want to be a professor, like a lecturer. And TAing hasn&#x2019;t made me want to do it less, but it hasn&#x2019;t like increased my love for it at all. It&#x2019;s just kind of added more stress to my plate.&#x201D; (Ray)</p>

<title>Perception of teaching experiences as a PhD student</title>
<p>The perception participants had of the importance of teaching experiences for PhD students varied, though participants felt that the general perception of teaching experiences by their peers was that they were undesirable or taking advantage of the students&#x2019; time when they were required.</p>
<p>Throughout their experiences in their PhD program, Aaron&#x2019;s peers generally viewed being a teaching assistant as a less desirable alternative to being a research assistant, as they would not be able to obtain more valuable research experience in the time spent as a TA.</p>
<disp-quote>
<p>&#x201C;In some places, like my previous department, a TA-ship is really considered something that&#x2019;s more like what you do when your professor doesn&#x2019;t have any money. Right? You were supposed to be on an RA more often than not, and the TA is more like, &#x2018;oh, I guess that grant didn&#x2019;t go through. Guess you&#x2019;ve got to go teach in the first year,&#x2019; or something like that.&#x201D; (Aaron)</p>
</disp-quote>
<p>In some programs where extensive TA experience is required, Austin described how they and their peers generally felt like they were forced to do work that should not be necessarily pushed onto them because of the intensive time commitment required. This sentiment was echoed to a lesser extent in interviews with participants who had required, but less extensive, TA experiences.</p>
<disp-quote>
<p>&#x201C;I think most people don&#x2019;t like [being required to be a TA for 2 semesters] It&#x2019;s a service that you give to the department as a PhD students because, here, you don&#x2019;t get a stipend from your TA normally, because most of students are on basically RA positions. I think one [semester] is okay for everyone but 2. Most people find it too much.&#x201D; (Austin)</p>
</disp-quote>
<p>However, the participants generally saw their own experiences as TAs positively, if overwhelming workload-wise depending on class size, and sought them out when not required.</p>
<p>Ray describes how, despite being at a point where teaching was no longer a requirement, she still wants to find more classroom-based experiences to learn more about teaching. However, Aaron, despite focusing on engineering education, describes how he was put in a position where he felt required to work significantly more than what TAs are generally expected to do as a PhD student.</p>
<disp-quote>
<p>&#x201C;&#x2026;at this point, my academic career is shaped around these types of like experiments, and more hands-on learning rather than classroom-based learning. But I am kind of trying to pursue more like classroom-based experiences because I want to teach after this. So, I&#x2019;m still trying to figure out how to like rope all that into my learning at this point&#x201D;. (Ray)</p>
</disp-quote>
<disp-quote>
<p>&#x201C;If you&#x2019;re [leading] a class of 120 students, There&#x2019;s no way that you&#x2019;re spending just 20 hours per week even, I, couldn&#x2019;t do it, [&#x2026;] and it made me realize like if I&#x2019;m going to be able to graduate in 4 years like I cannot do that again bbecause I was thinking so much time into that course just to just to do it effectively, right? And I wasn&#x2019;t even being that effective. I was doing a lot of minimizing my, but that&#x2019;s trying to like truncating as much as I could or delegate as much as I could just to make sure that I wasn&#x2019;t spending more than 20 HA week. I think the most I could get down to was like 25 on a particular week, but normally it was like 30 to 35 HA week just in that course.&#x201D; (Aaron)</p>
</disp-quote>
<p>While teaching was seen as a priority for the participants, both from a personal fulfilment standpoint as well as from an institutional importance perspective, teaching was generally seen as a secondary priority to research. It seems that the participants expect that the general difference in perceived value of TA and RA positions will extend to a similar difference in value in teaching and researching as faculty in the future. However, the participants still looked for ways to continue to find experience with teaching regardless.</p>

<title>Question 3: How have experiences in a PhD program shaped the expectations for working in-class as a primary instructor?</title>
<p>To understand how the students&#x2019; expected in-class experiences as instructors have been shaped, it is important to understand what their current experiences are and how they relate to their expectations. The experiences that PhD programs offer to their students are broad, varying from the practical shaping from TA and RA positions to the more social shaping from mentor-mentee relationships.</p>

<title>Anticipated difficulties</title>
<p>Calvin describes one expected difficulty as a reflection of his own experiences as an undergraduate student, where he was reluctant to do assignments on occasion. As a result, he knew the results of inadequate student work can be a result of a variety of reasons, including a genuine lack of understanding or a lack of interest in completing an assignment with full effort. However, this difficulty was not as severe as he expected when he led a class as a primary instructor.</p>
<disp-quote>
<p>&#x201C;I expected student resistance to work. I just from my experience, I was an undergrad at 1 point, and at 1 point I would get work and then be like, &#x2018;man. I don&#x2019;t wanna do this.&#x2019; Now, I was a pretty quiet undergrad, like I just didn&#x2019;t go talk to my professors at all, so if I didn&#x2019;t want to do homework. I just didn&#x2019;t do it, and then got the great hit. I have a concern that students just don&#x2019;t communicate or don&#x2019;t provide feedback [&#x2026;] in the way that if a student is struggling with something, I would like to know that a student is struggling with something. And it&#x2019;s sometimes really hard To know when that&#x2019;s the case or when that&#x2019;s not the case especially if the reason that their homework is not great is because they don&#x2019;t care to put in the effort as opposed to the reason, or because they don&#x2019;t understand the topic right. Those 2 things can produce homework that looks the exact same&#x2026; And so that&#x2019;s that&#x2019;s a that&#x2019;s a piece that I really was worried about, and I would say that I saw that to some degree, but it was not as bad as I expected it to be&#x201D;. (Calvin)</p>
</disp-quote>
<p>Amy describes being concerned about the workload they have observed being imposed on faculty around her, and they observe that the inflexible nature and scale of these requirements could make it difficult for her to acclimate to academic life. While some areas of difficulty were expected, there was also a mention of areas where the participants expected to succeed when they were put in a position to teach.</p>
<disp-quote>
<p>&#x201C;I&#x2019;ve seen some professors that really struggle with this [balancing the variety of responsibilities] and they like never have a second to breath and so I think that over the next couple of years they really need to have some hard conversations with professors about like what works for you, what doesn&#x2019;t, how do we avoid running into a problem where like I just don&#x2019;t have enough hours in my day.&#x201D; (Amy)</p>
</disp-quote>
<p>In general, there was a sentiment of concern regarding potentially being blindsided by unexpected questions. However, participants who had experience being a primary instructor found that this concern dissipated as they had more experience. While Ray felt unprepared about leading a classroom in terms of lacking knowledge or experience, the time they spent leading a classroom as a primary instructor helped them build confidence in their lectures.</p>
<disp-quote>
<p>&#x201C;I think prior to the TA experience, I think the biggest worry I had or the biggest challenge I thought I would face would be like, not really knowing what I had to teach, I guess. And like having to prepare lectures and like making sure I was clear and I was engaging students and like, worrying that they wouldn&#x2019;t be interested. [&#x2026;] In terms of like not knowing the content or like feeling like I wasn&#x2019;t prepared to teach, I think what I realized is a little bit of preparation was a long way.&#x201D; (Ray)</p>
</disp-quote>
<p>Bri, through her experiences as an undergraduate student, felt more comfortable in grading papers compared to having to lead a lab section as a PhD student. However, the faculty member who ran the lab ensured that she knew how the lab would be run.</p>
<disp-quote>
<p>&#x201C;Yeah, just that. I wouldn&#x2019;t be familiar with the lab stuff, but thankfully like, after meeting with Dr. [Redacted], who ran the lab like she would make sure that, like we could come in and run through the experiment with her to make sure that we felt comfortable running through it with the students. I was more familiar with the grading side of things. I&#x2019;d been like a grader as an undergrad before, and so like I feel pretty confident about that.&#x201D; (Bri)</p>

<title>Teaching preferences</title>
<p>There are as many preferences for teaching as there are teachers and students. These preferences can come from a variety of sources, ranging from experiences as a student to the circumstances surrounding a class.</p>
<p>Madison led an online summer session class as a primary instructor, where she was tasked with designing and presenting lectures. Madison expressed a preference for an interactive classroom, but the combination of the time constraints of a summer session and the format of an online classroom made this style of teaching feel less effective.</p>
<disp-quote>
<p>&#x201C;I made all the lectures. I wasn&#x2019;t the one doing the assignments, but I made all the lectures, and that was so time-consuming. I thought I&#x2019;d be able to come up with fun activities we could do in class, but there really wasn&#x2019;t time for that, because I was trying to go through whatever material they were supposed to know for the assignment and make sure I remembered how to do whatever it was in C, which I hadn&#x2019;t touched in years. It was just a lot of prep work that was never necessary as a TA.&#x201D; (Madison)</p>
</disp-quote>
<p>Calvin discusses how his experiences as an undergraduate student shaped his preferences for how to use assignments as an instructor. Specifically, he describes how he felt being given large amounts of homework was ineffective in preparing him in class as an undergraduate, and he responds to this feeling by designing his homework assignments to be more difficult and require more intentional effort by his students.</p>
<disp-quote>
<p>&#x201C;The thing that I would say is the same between the two, that maybe I didn&#x2019;t realize as much when I was an undergrad, is that I really enjoyed learning a lot. The thing I always found frustrating was having to do assignments or homework that didn&#x2019;t help me learn at all. That was what really frustrated me as an undergrad. As an instructor, I want to give homework to students that is going to try to challenge every student, because that&#x2019;s what provides learning for everyone. That&#x2019;s hard to do, right? Students are at different levels. But that&#x2019;s something I will always try to do: try to give opportunities for students to push further than what they know.&#x201D; (Calvin)</p>
</disp-quote>
<p>Imane was a TA for a lab section where she would spend time instructing students on how to complete the lab as well as guiding the students to complete the required tasks. While her experience as a student led her to feel that lectures are not the most effective way to teach most of the time, the circumstances of her position put her in a position where some form of lecturing is necessary to proceed.</p>
<disp-quote>
<p>&#x201C;The class is usually split between a lecture slash, I guess, well, I call it a lecture, but it&#x2019;s more like a presentation that walks students through what the lab will be about. Then there&#x2019;s the actual lab or the interactive activity in the second half, which builds on that initial lecture to give students more hands-on experience. I know I said that lecturing is an inefficient way for me to learn, but that also depends on how the lecture is structured. My adviser does a good job of making it feel less like a lecture and more like actually learning the material as if it were just discovered.&#x201D; (Imane)</p>

<title>Building confidence and skill</title>
<p>In addition to having their expectations and preferences on how they will teach, the participants also identified that they still have room for improving their teaching through a variety of means. To improve her teaching ability, Bri chose to take a course on developing teaching pedagogy, and she is also seeking opportunities to lecture in isolated, one-off situations, such as when a professor is away from campus, taking this approach to mitigate any negative effects she might have on here students because of her lack of experience and teaching skills.</p>
<disp-quote>
<p>&#x201C;I&#x2019;m taking our teaching and learning class, which is about developing teaching pedagogy. I&#x2019;ve had it for 2 days, and it&#x2019;s already been really helpful. So I&#x2019;m really hoping that like that will continue helping me feel more comfortable. I think I&#x2019;d honestly like I after getting together like that knowledge. I just need more experience. That&#x2019;s something I&#x2019;ll get through but also, usually TA-ing isn&#x2019;t like lecturing, and I think that&#x2019;s where I have like the least amount of confidence in. So I think that&#x2019;s something that I&#x2019;ll just have to practice, put myself in experiences that stretch me out of that comfort zone without screwing over everyone. I would never jump in and be like I&#x2019;m gonna teach a whole lecture course for a semester, but, I definitely would like to take over some lectures from like my advisors when they&#x2019;re out of town and somewhere where I can get like feedback on it, and it&#x2019;s always less stressful if you&#x2019;re like, okay, I&#x2019;m giving one lecture like, I can only screw up these people&#x2019;s education, so much in one lecture, like.&#x201D; (Bri)</p>
</disp-quote>
<p>Despite not having formal resources to help with the development of teaching skills, Calvin feels comfortable in asking faculty members for advice when he was leading a class as a primary instructor. Specifically, he discusses how he is comfortable asking for advice about dealing with situations as they arise, such as how to ensure an exam is the appropriate length.</p>
<disp-quote>
<p>&#x201C;The professors I have worked with have always been gracious to be communicable. So. A lot of the stuff that I have learned about teaching and whatnot are things that I have maybe some of them have picked up on my own, but some of them in broad strokes of how I learn how to run a lecture, and that sort of thing are things that I&#x2019;ve been able to go to various different professors, and then just had a chat with them about. Although there&#x2019;s not a like hard resource in place for that. There&#x2019;s a willingness from the different professors here to provide assistance (&#x2026;) in a &#x2018;I&#x2019;m happy to talk to you about how I teach a class, and run you through some of the things I consider there&#x2019; way&#x2026; Those professors were quite helpful. Although there&#x2019;s not like a hard resource, there are a lot of like soft resources or opt in resources. If I&#x2019;m going and looking for them, if that makes sense.&#x201D; (Calvin)</p>
</disp-quote>
<p>While not being the primary instructor of a course, Austin did have the experience of teaching several students and describes how the nervousness regarding presenting in front of a classroom started high but decreased over time.</p>
<disp-quote>
<p>&#x201C;I think the stress of standing up in front of so many people has decreased over time. I can feel it&#x2014;you get used to it, I guess. But in terms of the basic fluency of teaching the concept, I think the more you teach a course, the better it&#x2019;s going to be.&#x201D; (Austin)</p>
</disp-quote>
<p>Expectations for teaching the classroom experience have been shaped primarily by a combination of observations and experiences as a student, as well as experiences as a TA and, if applicable, experiences as a primary instructor. However, the overlap between expected difficulties and anxieties generally decreased after primary instructor experience.</p>

<title>Discussion</title>
<p>This study examines how engineering doctoral students begin forming expectations about teaching and mentoring before entering faculty roles, an area that remains underexplored in engineering education literature. While prior studies examine teaching identity after faculty entry or focus on TA preparation programs, this study highlights how doctoral experiences themselves function as formative spaces where future faculty expectations, teaching philosophies, and mentoring approaches are already being constructed.</p>
<sec id="sec29">
<label>5.1</label>
<title>Generation of teaching and mentoring philosophy</title>
<p>Most participants mentioned that they initially generated their notions of what was important teaching through their experiences as a student, while they clarified and adapted their teaching philosophy through their teaching experiences in their PhD program. This experience is reflected in <xref ref-type="bibr" rid="ref27">Korpan (2019)</xref>, which mentions that TAs begin their work with &#x201C;strong conceptions and dispositions relating to teaching,&#x201D; where they need support to learn how to reflect on their teaching and improving holistically (<xref ref-type="bibr" rid="ref27">Korpan, 2019</xref>). More specifically, the interactions between the participants and their advisors in their PhD program had great influence on their teaching philosophies. This reflects <xref ref-type="bibr" rid="ref33">Mena et al.&#x2019;s (2013)</xref> work, in which they found that TAs who were tasked with being class instructors would feel comfortable informally approaching faculty members they were familiar with to seek advice on the day-to-day teaching experience and on how to approach specific situations. Though this comfort may be a typical experience and not a universal experience, as discussed by <xref ref-type="bibr" rid="ref7">Buswell (2020)</xref>, where most engineering PhD students with an interest in teaching were encouraged to pursue a teaching-focused career while some felt they were not given this support and others felt resistance from their advisors.</p>
<p>In our study, Bri (Material Science, 2&#x202F;years into PhD program) discussed these effects through her experiences as a mentor to her religious group, where being a mentor encompassed a broad area of guidance, not just including the intended religious purpose, but also academic and personal guidance as well. These groups were effectively a counterspace, helping Bri build mentoring relationships and develop her mentoring philosophy outside of her academic groups (<xref ref-type="bibr" rid="ref2">Artiles et al., 2025</xref>). In <xref ref-type="bibr" rid="ref1">Ambler et al. (2016)</xref>, the academic and social benefits of mentoring are discussed, where the intertwining of personal and professional discussions gave way to self-reflection and new ways of thinking for not just the mentee, but the mentor as well. Similarly, <xref ref-type="bibr" rid="ref47">Sherwood et al. (2018)</xref> finds that serving as peer mentors can lead to personal and social benefits, such as the development of agency and communication skills. These benefits go on to help the transition into leadership roles (<xref ref-type="bibr" rid="ref47">Sherwood et al., 2018</xref>).</p>
<p>Taken together, these findings extend existing work on teaching identity by showing that doctoral students do not simply &#x201C;inherit&#x201D; teaching philosophies from prior experiences. Instead, they actively construct instructional and mentoring philosophies through a combination of observation, limited instructional roles, informal mentoring, and reflection during their doctoral training. This highlights doctoral education itself as an early and influential stage of faculty identity development, rather than viewing identity formation as something that primarily occurs after entering academic positions.</p>

<title>Teaching-research balance</title>
<p>Participants mentioned concerns regarding the balance of effort between teaching and research, where time spent teaching may be rewarded more if it were reallocated towards research. <xref ref-type="bibr" rid="ref55">Wankat et al. (2023)</xref> reflect this reasoning shown by the participants, stating that teaching and learning are much less rewarded than disciplinary research. While the imbalance of importance between teaching and research has been improving over time, the rewards structures in colleges of engineering generally still show preference towards research ability over teaching ability (<xref ref-type="bibr" rid="ref55">Wankat et al., 2023</xref>). While efforts are being made to encourage teaching through greater consideration in tenure processes, these efforts have not been universally successful in &#x201C;offsetting oversimplified approaches such as points schemes based on journal impact factors&#x201D; (<xref ref-type="bibr" rid="ref45">Schimanski and Alperin, 2018</xref>). Similarly, <xref ref-type="bibr" rid="ref40">Robert and Carlsen (2017)</xref> discuss how STEM professors felt that they were not adequately prepared for anything aside from research and suggest that the support offered to future faculty regarding pedagogy training should be considered separately from the type of support offered to current faculty, exposing them to more research-based teaching strategies. This is due to the idea that early experiences as doctoral students can exert a greater influence on professors.</p>
<p>While there is a common perception of teaching-research trade-offs in academia, <xref ref-type="bibr" rid="ref48">Shortlidge and Eddy (2018)</xref> find that PhD students investing in evidence-based learning is slightly positively related to research quality without a decrease in research productivity. In other words, teaching quality does not inherently compromise research quality or productivity but instead teaching and research can be synergistic (<xref ref-type="bibr" rid="ref48">Shortlidge and Eddy, 2018</xref>). Despite this, the academic lifestyle can bring about work-life imbalance and interfere with daily life (<xref ref-type="bibr" rid="ref6">Bowering and Reed, 2021</xref>). However, this is not to say that it is impossible to find sustainable lifestyles in academia, as there are ways to manage lifestyles in academia to find work-life balance and mental/physical wellness (<xref ref-type="bibr" rid="ref37">Owens et al., 2018</xref>). These concerns illustrate how participants are already internalizing institutional reward structures and projecting them onto their future academic roles, shaping how they anticipate balancing teaching and research long before becoming faculty.</p>
<p>In regard to the expectations of female engineering PhD students, Amy (Aerospace Engineering, 2&#x202F;years into PhD program) describes how she would like to be able, as a future faculty member, to mentor young women in aerospace engineering, citing her experiences feeling underrepresented in her undergraduate studies.</p>
<disp-quote>
<p>&#x201C;I think that becoming a faculty member is a really great place for me to be because I&#x2019;d get to mentor young women in engineering. During my undergrad, I had maybe two female professors, maybe. And one of them wasn&#x2019;t in aerospace. I had one female aerospace professor. That was definitely something I struggled with during undergrad. It&#x2019;s hard to fight for your degree when you don&#x2019;t see yourself represented in your department. So I think that becoming a faculty member might help other women in aerospace pursue their degrees, know that it&#x2019;s possible, and know that there&#x2019;s someone to talk to when they run into things that shouldn&#x2019;t still be happening in labs. Being a resource for them is really important: both in terms of how to deal with uncomfortable situations and how to get plugged into helpful groups. We have graduate women in engineering and women in aerospace groups. Getting connected with those communities can help them find people who look like them.&#x201D; (Amy)</p>
</disp-quote>
<p>Amy identifies this mentorship as being an important responsibility to her future students as a result of this lack of representation in undergraduate degrees. Similarly, <xref ref-type="bibr" rid="ref23">Judson et al. (2019)</xref> mention that higher female faculty also on average advise more students than male faculty, and <xref ref-type="bibr" rid="ref25">Kamerlin and Wittung-Stafshede (2020)</xref> discuss how, as one progresses through engineering higher education, the relative proportion of men increases, reinforcing Amy&#x2019;s experiences and compounding the amount of work she may end up doing as a faculty member. However, in terms of work-life balance, <xref ref-type="bibr" rid="ref51">Toffoletti and Starr (2016)</xref> state that female academicians often emphasize family commitments, regardless of parental status, in their descriptions of work-life balance. This specific detail was not mentioned by any of the female participants, though this may be due to a limited sample size or phrasing of questions.</p>
<p>These findings contribute to conversations on doctoral socialization by showing that perceptions of teaching-research trade-offs are not formed during faculty careers but are already embedded during doctoral training through observation of advisors, peers, and institutional norms. Doctoral students are not only learning how to conduct research, but also absorbing implicit messages about how teaching is valued in academia.</p>

<title>Expectations of the classroom experience</title>
<p>Participants&#x2019; expectations for classroom teaching were strongly shaped by the extent of their instructional exposure, revealing how even limited instructor-of-record experiences significantly recalibrate perceptions of teaching challenges and responsibilities. Those with experiences as primary instructors described the differences between their expected difficulties before and after their experiences.</p>
<p>As Tony (3&#x202F;years of instructor experience) and Austin (no instructor experience) illustrate, participants without experience as primary instructors typically are more concerned with their potential new role as an instructor and the social responsibilities that come with that role, whereas those with more experience are less concerned with the management of the social standards and more concerned with ensuring that students are able to effectively learn.</p>
<disp-quote>
<p>&#x201C;I thought it would be difficult to stand up and give the lecture, to answer questions on the fly. [&#x2026;] As it turns out, I&#x2019;m pretty good at making things up. I&#x2019;m pretty good at answering those kinds of questions. It hasn&#x2019;t been much of a challenge. If it is, I just keep a little notepad with me. I write it down. No big deal. I&#x2019;ll answer it tomorrow. [&#x2026;] I did not expect the level of diversity in the classroom at all. The fact that some people couldn&#x2019;t divide two numbers while others were talking about Kepler&#x2019;s laws, and they were sitting next to each other. I couldn&#x2019;t believe it. How do you deal with that? I&#x2019;m still not completely sure, but we&#x2019;re getting better.&#x201D; (Tony)</p>
</disp-quote>
<disp-quote>
<p>&#x201C;I think being stressed comes from the fact that you&#x2019;re going to stand up in front of a whole class, and everyone is looking at you. You want to teach them something, but at the same time, with the lack of experience you might have, there&#x2019;s always that lingering fear that you might be wrong about something. You also want to make sure you&#x2019;re teaching the concept as clearly as possible.&#x201D; (Austin)</p>
</disp-quote>
<p>One of the concerns expressed by the participants regarded managing student motivation. <xref ref-type="bibr" rid="ref31">Liu et al. (2012)</xref> emphasizes the importance of student motivation, illustrating how increased motivation results in a significant increase in academic performance. When students feel their assessments are unimportant, they do not try their best to maximize their results (<xref ref-type="bibr" rid="ref31">Liu et al., 2012</xref>). However, instructors are able to entice student motivation through the promotion of student engagement and providing an environment for mutual support between students (<xref ref-type="bibr" rid="ref50">Tinto, 2025</xref>). Interactions between students and faculty as well as the pedagogical techniques employed by faculty can increase motivation (<xref ref-type="bibr" rid="ref50">Tinto, 2025</xref>). Positive expectations for students by faculty can affect the expectations held by students, which in turn affects student motivation (<xref ref-type="bibr" rid="ref50">Tinto, 2025</xref>). Regarding the development of teaching skill and confidence, the participants identified both taking classes on pedagogy and having the experience of teaching classes as being keys to this development. This is reflective of how self-efficacy can develop as described by <xref ref-type="bibr" rid="ref3">Bandura (1997)</xref>, which finds that the vicarious experiences, physiological feelings, social persuasion, and mastery experiences affect one&#x2019;s self-efficacy. <xref ref-type="bibr" rid="ref58">Wendt et al. (2015)</xref> specifically discusses how engineering students without teaching design experience develop self-efficacy in teaching engineering design through the vicarious experiences of watching a more experienced teacher execute a similar activity as well as practicing implementing their own lessons in a controlled environment helped develop self-efficacy.</p>
<p>This finding extends prior literature on TA preparation and teaching confidence by demonstrating that expectations for teaching are not merely skill-based but perception-based. Instructor experience reshaped how participants understood student heterogeneity, workload, and instructional responsibility, suggesting that experiential exposure plays a critical role in aligning expectations with the realities of academic teaching.</p>
<p>Although this study did not explicitly compare teaching expectations across institutional types or student populations, participants&#x2019; expectations were nonetheless shaped by contextual factors embedded in their teaching and mentoring experiences. Expectations related to workload, student engagement, and instructional responsibility varied based on exposure to large versus small classes, laboratory versus lecture-based instruction, and online versus in-person teaching formats. Participants who had experience leading large classes or serving as primary instructors described heightened concerns regarding time management, student heterogeneity, and maintaining instructional quality, whereas those with limited teaching responsibility expressed fewer contextual concerns.</p>
<p>Additionally, while student body demographics were not directly addressed by participants, several expressed a growing sense of social responsibility and mentorship, particularly related to supporting underrepresented or marginalized students. These findings suggest that doctoral students&#x2019; teaching expectations are shaped not only by pedagogical experiences but also by perceived social and institutional responsibilities. Future research should explicitly examine how teaching expectations differ across institutional contexts (e.g., R1, teaching-focused, community colleges), student demographics (e.g., nontraditional, transfer, first-generation students), and instructional settings (e.g., large lectures, laboratories, hybrid environments).</p>
<p>To clarify the theoretical grounding of the findings, <xref ref-type="table" rid="tab4">Table 4</xref> maps the major emergent themes to the guiding theoretical perspectives informing this study. Although data analysis was inductive, teaching and mentoring identity formation, communities of practice, and self-efficacy theory served as sensitizing lenses during interpretation. This mapping illustrates how participants&#x2019; narratives align with established theoretical constructs while preserving the data-driven nature of the analysis.</p>

<p>The theoretical contribution of this study lies in its integration of identity formation, communities of practice, and self-efficacy perspectives to explain how engineering doctoral students develop expectations for teaching and mentoring prior to entering faculty roles. By empirically demonstrating that these expectations emerge through multiple formal and informal experiences rather than through replication of prior instruction alone, this study extends existing theoretical work by highlighting the early and often under examined phase of faculty identity development during doctoral training.</p>
<p>Notably, one participant explicitly connected her desire to mentor students to her experiences as a woman in an underrepresented engineering field, highlighting how identity and representation can influence perceptions of teaching and mentoring responsibility. Although this study did not aim to compare perspectives across demographic groups, participants&#x2019; narratives suggest that personal background and lived experiences may shape how doctoral students conceptualize teaching and mentoring. For example, some participants discussed mentorship in relation to representation and supporting underrepresented students, while others reflected on how their years of teaching experience influenced their confidence and expectations for classroom management. These observations indicate that factors such as gender, prior teaching exposure, and stage within the doctoral program may influence how teaching and mentoring philosophies are formed. Future research could more intentionally examine how demographic characteristics intersect with doctoral training experiences to shape expectations of academic teaching roles.</p>
<p>Overall, this study contributes to engineering education literature by positioning doctoral training as an overlooked but critical phase in the formation of future faculty teaching and mentoring expectations. Rather than focusing on formal TA training or early faculty development, this work demonstrates how informal experiences, observation of faculty, and limited instructional roles during doctoral study collectively shape how future instructors conceptualize their academic responsibilities.</p>

<title>Limitations</title>
<p>A limitation of this study is that it does not explicitly disaggregate teaching expectations by institutional type, student demographics, or instructional format; instead, it captures expectations as they emerge from doctoral students&#x2019; localized experiences within their programs. Another limitation of this study is its focus on engineering doctoral training within the United States, primarily at R1 research-intensive institutions. Doctoral training models, expectations for teaching, and faculty responsibilities differ substantially across international contexts and institutional types, such as teaching-focused universities or community colleges. While this study does not attempt to compare these contexts, explicitly situating the findings within the U.S. R1 system is important for appropriate interpretation. Future research should examine how teaching and mentoring philosophy development differs across national contexts and institutional missions.</p>
<p>This study is exploratory and context-specific, drawing on in-depth interviews with a small group of engineering doctoral students situated within U.S. R1 institutions. While the sample size supports rich, detailed analysis, the findings are not intended to be generalized across all doctoral training contexts. Instead, the study offers nuanced insights that may resonate with readers in similar institutional environments and provides a foundation for future research examining teaching and mentoring expectations across broader and more diverse contexts.</p>

<title>Conclusion</title>
<p>This exploratory qualitative study examined how engineering doctoral students in U.S. research-intensive (R1) institutions develop expectations about teaching and mentoring as future faculty members. Through in-depth interviews, the findings revealed that participants&#x2019; teaching and mentoring philosophies are not formed solely through replication of how they were taught or mentored. Instead, these philosophies emerge from a combination of formal teaching assistantships, informal mentoring experiences, peer interactions, observation of faculty practices, and non-academic mentoring contexts. These experiences collectively shape how doctoral students understand their instructional roles, anticipate classroom challenges, and perceive the responsibilities associated with teaching in academia.</p>
<p>A key contribution of this study lies in highlighting how doctoral training environments function as formative spaces for early teaching and mentoring identity development. Participants&#x2019; reflections demonstrate that even limited instructional exposure, such as TA roles or informal mentoring, plays a significant role in shaping expectations for future faculty work. These findings suggest that doctoral programs need not rely solely on formal pedagogy courses to influence teaching preparation; rather, intentional structuring of teaching, mentoring, and observation opportunities can meaningfully support the development of future educators.</p>
<p>The study also has implications for policy and curriculum design within engineering doctoral programs. Institutions may consider expanding structured opportunities for doctoral students to engage in teaching beyond traditional assistantships, providing mentorship around instructional practice, and creating spaces for reflection on teaching experiences. Recognizing teaching and mentoring as developmental components of doctoral education, rather than peripheral responsibilities, may better prepare future faculty for the multifaceted demands of academic roles.</p>
<p>As an exploratory, context-specific study situated within U.S. R1 institutions, this research emphasizes depth and contextual insight rather than generalization. The small sample size enabled rich descriptions of participants&#x2019; experiences, allowing readers to assess the transferability of the findings to their own contexts. Limitations include the focus on a single national context, the absence of explicit demographic subgroup analysis, and the reliance on self-reported perceptions rather than observed teaching practices.</p>
<p>Future research may examine how teaching and mentoring expectations differ across institutional types, national contexts, and student demographics, as well as how these expectations evolve as doctoral students transition into faculty roles. Longitudinal studies following doctoral students into early faculty positions may further illuminate how early expectations align with actual teaching experiences. By providing a nuanced understanding of how engineering doctoral students begin to conceptualize teaching and mentoring before entering academia, this study contributes to ongoing conversations about preparing future faculty and strengthening the instructional dimension of doctoral education.</p>
