<title>Introduction</title>
<p>Language teaching aims to improve learners&#x2019; linguistic and cultural skills (<xref ref-type="bibr" rid="ref4">Byram and Risager, 1999</xref>). Culture plays an essential role in language learning and teaching, and this role requires careful attention. Incorporating culture enhances communication and encourages students&#x2019; acceptance of diverse cultures (<xref ref-type="bibr" rid="ref28">&#x00D6;nalan, 2005</xref>). In both spoken and written interactions, a lack of cultural and intercultural skills can cause communication failures, misunderstandings, or violations of cultural norms (<xref ref-type="bibr" rid="ref13">Farnia and Sattar, 2015</xref>).</p>
<p>Coursebooks are a fundamental part of the curriculum (<xref ref-type="bibr" rid="ref16">Guerrettaz and Johnston, 2013</xref>), serving as a structured body of knowledge and a de facto syllabus for classroom instruction, student learning, and assessments (<xref ref-type="bibr" rid="ref1">Apple and Christian-Smith, 1991</xref>). Cultural content analysis of coursebooks has gained more attention (<xref ref-type="bibr" rid="ref40">Tomlinson, 2012</xref>), and the quality and appropriateness of the language and content in coursebooks have been the subject of many studies (<xref ref-type="bibr" rid="ref15">Gray, 2010</xref>; <xref ref-type="bibr" rid="ref2">Baleghizadeh et al., 2020</xref>; <xref ref-type="bibr" rid="ref31">Rahim and Daghigh, 2019</xref>). However, the practical use and full potential of the epistemic and heuristic capabilities of coursebooks are not immediately clear (<xref ref-type="bibr" rid="ref30">Radford, 2012</xref>). Relying only on structural analysis of textbook content makes it hard to determine whether the coursebook achieves its intended goals (<xref ref-type="bibr" rid="ref21">Littlejohn, 2011</xref>; <xref ref-type="bibr" rid="ref25">McGrath, 2013</xref>). Although this type of in-depth examination is essential for understanding the holistic effectiveness of educational materials, the utilization of textbooks remains an underexplored area of educational research (<xref ref-type="bibr" rid="ref37">Rezat et al., 2021</xref>). Content analyses of coursebooks lack connection to classroom situations and do not address how teachers use them or how students perceive them (<xref ref-type="bibr" rid="ref26">Menkabu and Harwood, 2021</xref>). Just as <xref ref-type="bibr" rid="ref1001">Alshumaimeri and Alharb (2024)</xref> suggested, teachers&#x2019; cognition of teaching materials and their use are key variables that affect teaching effectiveness. Therefore, ignoring teachers&#x2019; use leaves a large &#x201C;black box&#x201D; in our understanding of the actual mechanism by which culture is transmitted in the classroom.</p>
<p>In response to the call to learn from materials use education research (<xref ref-type="bibr" rid="ref18">Harwood, 2021</xref>; <xref ref-type="bibr" rid="ref20">Li and Xu, 2020</xref>), the scarcity of studies examining how teachers utilize materials both inside and outside the classroom (<xref ref-type="bibr" rid="ref18">Harwood, 2021</xref>; <xref ref-type="bibr" rid="ref24">Matsumoto, 2019</xref>) and investigate the implementation of China&#x2019;s latest round of curriculum reform, this study addresses the often overlooked aspect of language pedagogy: materials usage. It specifically focuses on how teachers utilize the cultural content of language coursebooks. The research focuses on secondary EFL teachers&#x2019; use of prescribed textbook cultural content in China&#x2019;s secondary education. This study seeks to deepen our understanding of teachers&#x2019; decision-making processes when incorporating cultural content from curriculum materials in this context, and to reveal the underlying reasons behind these decisions. Additionally, a more detailed understanding of classroom-based curriculum enactment could enhance our conceptual grasp of material use as a basic yet complex teaching practice. To meet these goals, we conducted a qualitative case study to explore two specific research questions.</p>

<title>Cultural concepts and their content divisions</title>
<p>Academic perspectives on the connotations of culture vary. Some definitions have focused on the spiritual aspects of culture. For instance, <xref ref-type="bibr" rid="ref42">Tylor (1871)</xref> stated that &#x201C;culture is a complex whole that includes knowledge, beliefs, arts, morals, laws, customs, and any other capabilities and habits acquired by man as a member of society.&#x201D; <xref ref-type="bibr" rid="ref10">Cortazzi and Jin (1999)</xref> believed that culture is &#x201C;a framework of ideas and beliefs used to explain the behavior, speech, and thoughts of others.&#x201D; Additionally, some definitions consider both the spiritual and material aspects of culture. For example, <xref ref-type="bibr" rid="ref27">Moran (2009)</xref> points out that culture is a way of life that has continuously evolved through the historical process of human society. It is not just a pattern of behavior but also encompasses a set of deeply rooted, common practical beliefs. From the above definitions, it can be concluded that although they emphasize different aspects of culture, they all agree that culture is composed of diverse and rich elements, a collection that encompasses a wealth of material and spiritual content that gradually forms during the developmental process of human society.</p>
<p>Given the different geographical sources of culture, the study of cultural origins primarily relies on the classification methods of <xref ref-type="bibr" rid="ref10">Cortazzi and Jin (1999)</xref> and <xref ref-type="bibr" rid="ref19">Kachru and Nelson (1996)</xref>. They categorized culture by geographical characteristics into target-language culture (inner-circle national culture), international culture, learners&#x2019; native-language culture, and shared culture. <xref ref-type="bibr" rid="ref27">Moran&#x2019;s (2009)</xref> five categories includes cultural products, concepts, figures, communities, and practices. This category not only deepened the multidimensionality of cultural elements but also provided a more comprehensive perspective for cultural studies (<xref ref-type="bibr" rid="ref27">Moran, 2009</xref>).</p>

<title>Concept of English coursebook&#x2019;s cultural content</title>
<p>The latest <italic>Chinese General High School English Curriculum Standards (2017 Edition, 2020 Revision)</italic>, promulgated and implemented in China, elaborates on the rich elements in English coursebooks. It clearly states that cultural knowledge includes both material culture from Chinese and foreign cultures, such as traditional festivals, food, and clothing, as well as inventions and creations, and intangible culture, such as philosophical thought, values, social norms, arts education, and esthetic tastes.</p>
<p>English coursebooks present different language content in sections, including listening and speaking, reading, writing, and viewing, to cultivate students&#x2019; abilities in these areas. Among them, the reading section, a key area for developing reading and writing competence, is one of the most emphasized sections in EFL teaching. Coursebook reading texts, an important part of language teaching development, incorporate diverse cultures and serve as a significant medium for cultural education (<xref ref-type="bibr" rid="ref5">Cheng and Cong, 2022</xref>). Cultural theme reading texts and exercises are not only the core materials for language learning but also a vital means of transmitting cultural knowledge, forming a systematic cultural knowledge system. Therefore, in this study, the cultural content of coursebooks refers to the reading section that contains cultural theme reading texts and their accompanying exercises. Moreover, the cultural content of reading text is characterized by two dimensions. Firstly, it encompasses various geographical sources of culture, including Chinese culture, cultures of English-speaking countries, international culture, and common human culture. Secondly, it involves diverse cultural classifications, incorporating concrete material elements at the material level, such as cultural products, practical activities, and cultural individuals (e.g., traditional festivals, poetry, and songs), as well as conceptual elements at the spiritual level, such as cultural concepts (e.g., thought connotations and values).</p>

<title>Teachers&#x2019; use of coursebook</title>
<p>Despite the large number of studies published on second language resources (<xref ref-type="bibr" rid="ref17">Harwood, 2010</xref>; <xref ref-type="bibr" rid="ref25">McGrath, 2013</xref>; <xref ref-type="bibr" rid="ref39">Tomlinson, 2008</xref>, <xref ref-type="bibr" rid="ref40">2012</xref>), more attention has been paid to the cultural content of coursebook analysis (<xref ref-type="bibr" rid="ref45">Zhang et al., 2022</xref>; <xref ref-type="bibr" rid="ref46">Zhang and Nordin, 2025</xref>). To compare the effort dedicated to researching material content with that focused on material usage, less work has been conducted on the latter compared to the former (<xref ref-type="bibr" rid="ref24">Matsumoto, 2019</xref>; <xref ref-type="bibr" rid="ref18">Harwood, 2021</xref>). The majority of studies view textbooks as static analytical objects (<xref ref-type="bibr" rid="ref45">Zhang et al., 2022</xref>; <xref ref-type="bibr" rid="ref46">Zhang and Nordin, 2025</xref>; <xref ref-type="bibr" rid="ref2">Baleghizadeh et al., 2020</xref>; <xref ref-type="bibr" rid="ref31">Rahim and Daghigh, 2019</xref>). It is committed to accurately depicting the &#x201C;supply status of their cultural content, and assumes that this supply will directly determine the students&#x201D; &#x201C;reception&#x201D; effect.</p>
<p>Teachers&#x2019; research on the use of curriculum materials has focused on different aspects. For example, teachers use curriculum materials in various ways, including offloading, adapting, and improvising (<xref ref-type="bibr" rid="ref3">Brown, 2009</xref>); reading, evaluating, and reinterpreting (<xref ref-type="bibr" rid="ref38">Sherin and Drake, 2009</xref>). Influencing factors (<xref ref-type="bibr" rid="ref32">Rathert and Cabaro&#x011F;lu, 2021</xref>; <xref ref-type="bibr" rid="ref34">Remillard, 2005</xref>) and the educational function of materials on teachers (<xref ref-type="bibr" rid="ref33">Reisman and Fogo, 2016</xref>) are also the primary research points. They mainly sought answers to <italic>how</italic> and <italic>why</italic> teachers used materials through lesson observations and interviews.</p>
<p>Two studies warrant particular consideration because of their relevance to the current study. One was the study by <xref ref-type="bibr" rid="ref26">Menkabu and Harwood (2021)</xref> on teachers&#x2019; use of the Medical English Coursebook. It revealed that different teachers used the curriculum materials differently, mainly influenced by exams and learners&#x2019; needs. The study found that teachers&#x2019; material usage was more akin to that of Shawer&#x2019;s curriculum developers and makers. Another study by <xref ref-type="bibr" rid="ref45">Zhang et al. (2022)</xref> examined research EFL teachers&#x2019; adaptation profiles in coursebooks. The findings revealed that EFL teachers predominantly exhibit four distinct coursebook-adaptation profiles: Highly Active, Moderately Active, Lowly Active, and Adding-Deleting-Oriented. The four profiles differed significantly in the distribution of teachers by professional title, students&#x2019; learning ability, training in the use of a coursebook, and other factors. Teachers intended to regard coursebooks as resources rather than scripts. As a whole, teachers&#x2019; use of materials is a dynamic and complex process, and teachers usually make efforts to adapt coursebooks to ensure effective learning among learners (<xref ref-type="bibr" rid="ref14">Graves and Garton, 2014</xref>; <xref ref-type="bibr" rid="ref23">Masuhara et al., 2017</xref>).</p>

<title>Theoretical framework</title>
<p>This study adopts <xref ref-type="bibr" rid="ref34">Remillard&#x2019;s (2005)</xref> participatory framework. The participatory framework provides a theoretical framework for examining and interpreting teachers&#x2019; utilization of curriculum materials. Participatory framework derived from literature on teachers&#x2019; use of curriculum materials, Remillard noted that while this body of research provided some insights into curriculum material usage&#x2014;such as understanding that using curriculum materials is not a simple proposition&#x2014;it did not offer specific strategies for how teachers should use these materials or conduct their teaching. It also failed to characterize the relationship between teachers and curriculum materials clearly. To address this gap, Remillard proposed a participatory framework for teachers&#x2019; use of curriculum materials grounded in social-cultural theory. Remillard extracted the implicit relationships among coursebooks, teachers, and curricula in the structure of teachers&#x2019; use and their respective potential theoretical influences. Participatory framework provides a comprehensive elucidation of this complex and multifaceted interaction, shedding light on the various dynamics and interdependencies involved (<xref ref-type="bibr" rid="ref34">Remillard, 2005</xref>). This is also the reason why the study chose it as the theoretical framework.</p>
<p>Remillard&#x2019;s participatory framework posits that teachers and curriculum materials are integrally linked in the design and implementation of planned and enacted curricula (<xref ref-type="bibr" rid="ref3">Brown, 2009</xref>; <xref ref-type="bibr" rid="ref34">Remillard, 2005</xref>). This framework elucidates how artifacts and tools facilitate human activity (<xref ref-type="bibr" rid="ref8">Cole and Engestr&#x00F6;m, 1997</xref>; <xref ref-type="bibr" rid="ref43">Vygotsky, 1978</xref>). In the participatory framework, curriculum materials are regarded as artifacts; teachers&#x2019; use of them is seen as human interaction with artifacts or tools (<xref ref-type="bibr" rid="ref34">Remillard, 2005</xref>). The core assumption of this framework is that there is a dynamic interrelationship between teachers and curriculum materials, in which both teachers and texts engage. A notable feature of this framework is its focus on the use and participation activities of curriculum materials, as well as the interactive relationship between teachers and curriculum materials. It can be said that the participatory framework views the use of curriculum materials as a &#x201C;collaboration&#x201D; between teachers and curriculum materials.</p>
<p>The participatory framework, which suggests a direct, hierarchical relationship between teachers and curriculum materials, highlights a more vibrant, dialectical, and interactive connection (<xref ref-type="bibr" rid="ref34">Remillard, 2005</xref>). The participatory framework focuses on the entire process of teachers&#x2019; use of curriculum materials during the planning and classroom implementation phases. This framework provides a theoretical lens for understanding and interpreting the abundant phenomenon of teachers&#x2019; daily use of curriculum materials.</p>
<p>The main elements of the framework are teachers and curriculum material. The interactive participation between them urges teachers to develop their own curriculum based on curriculum design. Meanwhile, the process of implementing curriculum development is influenced by teaching circumstances and students. The framework primarily focused on four elements: (a) teachers, (b) curriculum materials, (c) their inter-participation relationships, and (d) the planned and enacted curriculum.</p>

<title>Chinese English language teaching context</title>
<p>As China embarks on a new round of curriculum reform, it has successively promulgated a new edition of the &#x201C;English Curriculum Standards&#x201D; for primary and secondary school teaching. One of the most significant changes was the emphasis on the humanistic educational function of the English curriculum, which clearly proposed the curriculum goal of &#x201C;cultural awareness. Curriculum materials serve as catalysts for curriculum reform and significantly influence teachers&#x2019; instructional practices (<xref ref-type="bibr" rid="ref36">Remillard et al., 2019</xref>; <xref ref-type="bibr" rid="ref6">Cohen, 1988a</xref>). Generally, how reform ideas are incorporated into curriculum resources is examined post facto through the content analysis of materials (<xref ref-type="bibr" rid="ref35">Remillard and Kim, 2020</xref>). However, static textual analysis of textbook content cannot capture user feedback on newly integrated reform concepts; only through teachers&#x2019; actual use of the materials can the development process be informed (<xref ref-type="bibr" rid="ref40">Tomlinson, 2012</xref>).</p>
<p>To achieve the curriculum goal of &#x201C;cultural awareness,&#x201D; Chinese English coursebooks for certain grades at the secondary school have been rewritten and implemented. To date, all versions of senior high school English coursebooks have been completed and implemented in practical teaching.</p>

<title>Participants</title>
<p>Following the intensity sampling principle (<xref ref-type="bibr" rid="ref29">Patton, 2005</xref>), teacher participants were selected based on their willingness to discuss their use of the coursebook. Two senior high school teachers (Alice and John, both pseudonyms) participated in this study. Both teachers are non-native English speakers, each holding a master&#x2019;s degree in applied linguistics. Their participation brought a diverse range of teaching experiences. Alice has 3 years of teaching experience at a municipal key high school, representing the early phase of a teaching career. John has a decade of experience teaching at a provincial key high school. Additionally, these two teachers used different coursebooks in their instruction. The different school settings allowed us to analyze how these complex factors interacted to influence teachers&#x2019; use of cultural content and their teaching decisions. The textbooks used by the two teachers are the second volume of compulsory high school English, published by the People&#x2019;s Education Press, and the third volume of compulsory high school English, published by the Foreign Language Teaching and Research Press.</p>

<title>Data collection</title>
<p>This qualitative approach aims to gather data on teachers&#x2019; curriculum practices in their natural settings (<xref ref-type="bibr" rid="ref11">Creswell, 2007</xref>; <xref ref-type="bibr" rid="ref12">Dornyei, 2007</xref>). Conducting qualitative classroom-based research on the use of second-language materials advances this field (<xref ref-type="bibr" rid="ref17">Harwood, 2010</xref>). The comprehensive data sources for this study included classroom observations, which were systematically recorded and analyzed for interactions and teaching practices. Additionally, semi-structured interviews were conducted to provide more nuanced and personalized insights into their experiences and perspectives. Furthermore, the study included an analysis of teachers&#x2019; textual materials, including lesson plans, instructional guides, and other relevant documents, which provided a contextual backdrop for the teaching strategies employed.</p>

<title>Data analysis</title>
<p>Since all the data in this study were textual, content analysis was used. Coding was guided by the research question on how teachers used the language coursebook and the factors that influenced their use. Through repeated discussions, we identified commonalities and differences in teachers&#x2019; use of language course books. Teachers typically adapt their materials before, during, and after teaching (<xref ref-type="bibr" rid="ref41">Tomlinson and Masuhara, 2018</xref>). Based on the teachers&#x2019; interactive use of curriculum materials in three different phases, namely, pre-, mid-, and post-lesson, the transcriptions were classified into three parts.</p>
<p>By comparing what the teachers said and what they did in class, classroom observations were transcribed verbatim to capture the teachers&#x2019; enacted instruction. Furthermore, all documents, including transcribed classroom observations, interviews, and textual materials, were analyzed according to the <xref ref-type="bibr" rid="ref9">Corbin and Strauss (2015)</xref> framework of open, axial, and selective coding. The participants reviewed all transcriptions for member checking.</p>

<title>Findings</title>
<p>Based on the theoretical framework, this study examines how teachers use cultural content in coursebooks and the factors that influence this practice. Results from classroom observations, teacher interviews, and text analysis reveal that teachers&#x2019; use of cultural content in textbooks occurs in four stages, shaped by five factors. Specifically, these stages are reading and clarifying objectives, evaluating cultural content, adapting cultural content, and reflecting on its use. According to the framework of this study, reading and evaluating cultural content in textbooks are the main steps in teachers&#x2019; planning, while adapting the content is central to lesson implementation. Reflecting on the use of cultural content happens during the final stage, when teachers consider their process. Each stage is supported by evidence that uncovers the reasons behind teachers&#x2019; decision-making, as detailed below.</p>

<title>Use of cultural content of the coursebook</title>
<sec id="sec15">
<label>6.1.1</label>
<title>Reading and clarifying objectives</title>
<p>The first and foremost prominent stage that emerged in teachers&#x2019; cultural content is reading and clarifying objectives. Before implementing cultural content teaching, both participating teachers acknowledged their commitment to reading and clarifying the curriculum teaching objectives from the texts, as evidenced by the following excerpts:</p>
<disp-quote>
<p>
<italic>I typically analyze the cultural content of reading materials to clarify their teaching objectives. Throughout this stage, I strive to align cultural content objectives with the curriculum goals, ensuring that the instruction of cultural content in reading materials is designed to fulfill them (Alice&#x2019;s pre-lesson interview).</italic>
</p>
</disp-quote>
<disp-quote>
<p>
<italic>I think it is necessary to clarify the teaching goals, identify &#x201C;implicit&#x201D; teaching points from a general discourse reading, and develop a cultural content teaching plan with clear instructional objectives (John&#x2019;s pre-lesson interview).</italic>
</p>
</disp-quote>
<p>John pointed out that repeatedly reading the text, understanding its cultural content, and referring to the exercises at the end can clarify the text&#x2019;s teaching objectives and its relationship to the course objectives. For instance, in one of John&#x2019;s teaching segments, the thematic context is humans and society, and the text type is an expository essay on festival themes. The text mainly introduces the significance of festivals and the evolution of their connotations. Through in-depth reading, John distilled the text&#x2019;s cultural teaching goals.</p>
<p>Alice believed that the teaching objectives for cultural content should be clarified and derived from perspectives on Chinese and other countries&#x2019; cultures, thereby further clarifying the teaching objectives of this cultural theme reading discourse and providing a clear objective foundation for better teaching. Alice distilled out the cultural values and ideological connotations embedded in a reading passage of a world-famous artistic work: first, by the quintessence of Chinese nation&#x2019;s culture, further illustrating that art knows no borders and that various cultures of the world should each be appreciated for their own beauty and comparing different interpretations of Hamlet in Chinese and Western cultures, this text highlights the unique aspects of the Peking Opera version of Hamlet, highlighting the charm of traditional Chinese art. This leads students to understand and appreciate harmonious coexistence. Second, the text reflects the current trend of cultural communication and integration between Chinese and Western cultures, suggesting that cultural exchange among nations is also a significant means of cultural innovation. We should be adept at embracing and be enthusiastic about innovation.&#x201D;(Alice&#x2019;s teaching plan).</p>
</sec>
<sec id="sec16">
<label>6.1.2</label>
<title>Evaluating cultural content</title>
<p>Evaluation of cultural content is intertwined with the first stage. In the process of reading and clarifying objectives, both teachers have another important task: to evaluate cultural content and clarify its latent cultural concepts, thereby developing their teaching plan and designing teaching activities that are suitable for their students&#x2019; learning level and competence. Teachers&#x2019; evaluations of cultural content in textbooks will also involve consulting other resources of cultural content and adding relevant cultural content. Their evaluations influence the development of their teaching plan and also affect the process of adapting cultural content in textbooks.</p>
<p>For instance, John found that, in a reading text. Halloween and the European harvest festival are key elements of the discourse theme, the introduction to their development and origins was very brief. During the reading and evaluation, John finds that there is insufficient information on the related cultural content and decides to search for more on the historical development and evolution of the festivals mentioned in the text. Similar to John, Alice noted that, during the process of reading and clarifying the objectives of the cultural content, she found the reading passage lacked sufficient detail to elucidate the deep cultural concepts in &#x201C;Hamlet.&#x201D; Therefore, she decided to search for more materials to supplement the reading text and achieve the purpose of profound cultural concept teaching.</p>
<disp-quote>
<p>
<italic>This is not conducive to students&#x2019; understanding of the cultural value of this classic masterpiece, nor to the connection and differences between the artistic expressions of Chinese and foreign cultures during the learning process (Alice&#x2019;s post-lesson interview).</italic>
</p>
</disp-quote>
</sec>
<sec id="sec17">
<label>6.1.3</label>
<title>Adapting</title>
<p>After evaluating the cultural content of coursebooks, teacher will adapt their use based on the evaluation results. As McDonough et al. (2013) demonstrated, material adaptation is intrinsically linked to the evaluation of these materials through use. Adaptation is an inevitable and necessary procedure to ensure a match between the materials and learners (<xref ref-type="bibr" rid="ref41">Tomlinson and Masuhara, 2018</xref>). In this study, both teachers&#x2019; adaptation strategies included two sub-steps: supplementing and adjusting.</p>
<p>After reading and evaluating the text&#x2019;s cultural content, both teachers drew on their existing cultural resources and considered how they understood and learned it. From the perspective of being English learners, they thought about which strategies, such as adding, deleting, supplementing, and adjusting, could be adopted and what cultural teaching methods could be used to teach the cultural content more effectively. When implementing these strategies, teachers also considered their students&#x2019; learning contexts and abilities to ensure they are both feasible and practical. Teachers&#x2019; adaptation was evident through the introduction of new knowledge or the provision of scaffolding.</p>
<sec id="sec18">
<label>6.1.3.1</label>
<title>Supplementing relative cultural content</title>
<p>Supplementation is a method by which teachers add more relevant information to the cultural content of reading texts and their accompanying exercises. During the first two stages, teachers found that the cultural content of reading texts needs further supplementation and improvement.</p>
<p>After assessing the reading text of Hamlet, Alice pointed out that it was insufficient to achieve the objectives of cultural awareness. Therefore, she searched for additional related cultural content and incorporated it into her teaching plan, thereby advancing the achievement of cultural content teaching objectives. After searching for the text&#x2019;s cultural content, Alice finds three types of related material: textual, audiovisual, and pictorial. Based on the cultural content in the discourse and considering the students&#x2019; learning levels, Alice selected important excerpts from the Western drama Hamlet and the Peking opera The Prince&#x2019;s Revenge for the audiovisual materials, as well as photos of the Peking opera and Western drama costumes and stage settings. These are used to supplement the cultural content of reading texts, providing vivid and symbolic forms for teaching the abstract value connotations of Hamlet and offering clues for thinking about and understanding them.</p>
<p>Similarly, by engaging in the meticulous process of reading and thoroughly evaluating the cultural content embedded in the text, John embarked on a quest to delve deeper into the multifaceted aspects of the various festivals prominently featured in the reading material. John sought to uncover the intricate details of the origins, developments, and cultural customs of the festivals included in the reading text. In his quest for a comprehensive understanding, he selected the historical origins and developmental changes of four festivals&#x2014;Halloween, Harvest Festival, Spring Festival, and Mid-Autumn Festival&#x2014;as supplementary materials for the text&#x2019;s cultural content. The aim is to provide a dynamic, comprehensive portrayal of cultural content to support the implementation of cultural teaching objectives and the development of cultural awareness.</p>
</sec>
<sec id="sec19">
<label>6.1.3.2</label>
<title>Adjusting cultural content</title>
<p>In addition to collecting and supplementing appropriate cultural content, two teachers also read other sections of the same unit, selecting cultural content from related sections on reading and integrating it into the cultural content of the reading text to enrich and improve it.</p>
<p>Taking the reading text on festivals as an example, John found that the listening and speaking, reading and writing, and video sections were all centered on activities related to different Chinese traditional festivals. Among them, the video section focuses on the Lantern Festival, which students are all familiar with. To activate students&#x2019; learning enthusiasm and stimulate their thinking about the connotative meaning of the text&#x2019;s theme, he decided to adjust the Lantern Festival in the video section as a pre-reading task for the reading text.</p>
<p>Alice&#x2019;s adjusting related content from other sections within the unit was also employed. Having carefully examined and assessed the teaching content and activity tasks within each section of the unit, Alice discovered that other sections also featured numerous artworks aimed at helping students understand and appreciate art as a unique cultural symbol. Alice decided to use the Starting-Out video as an introduction to text teaching, the ballet <italic>The Peony Pavilion</italic> from Using Language as a medium for extending other artistic works that blend Chinese and foreign arts, and the practice tasks from the Presenting Ideas and Project sections as activity forms following text-based teaching.</p>
<p>In addition to adjusting other relevant materials within the unit into the reading text, two teachers made timely adjustments to the pre-established learning tasks based on the students&#x2019; classroom responses during the teaching phase. For example, during the while-reading stage, John guides students to focus on the central cultural concept of each paragraph, asking them to read and identify the main idea, thereby effectively helping them understand the text&#x2019;s cultural concepts. However, when dealing with parts where students had difficulty extracting the main ideas of paragraphs and texts, John adopted an adjustment strategy of removing the original activities and guiding students to focus on the first and last sentences of paragraphs, which effectively helped students complete the teaching tasks (John&#x2019;s classroom observation).</p>
<p>In the post-lesson interview, John reflected on classroom problems and noted that they might have stemmed from unfamiliar festivals appearing within the same paragraph. Coupled with limited time for classroom reading, students found it difficult to grasp the texts&#x2019; main ideas. Therefore, John decided to adjust the teaching plan for problematic parts after class and optimize the related tasks.</p>
<p>While dealing with student difficulties, Alice also adjusted the teaching plan, as highlighted below: in the task where the teacher asks students to predict the answer based on the title, students have difficulty answering the question &#x201C;What does Hamlet refer to?&#x201D; Alice encountered this situation and immediately adjusted the approach, prompting students to label the photo of a play from Hamlet as either Chinese or Western culture, while the teacher prompts students that Hamlet is a play from&#x2026; So it refers to&#x2026; The aim is to present students with the cultural background of Hamlet to ensure they can be guided to the correct answer (Alice&#x2019;s classroom observation).</p>

<sec id="sec20">
<label>6.1.4</label>
<title>Reflecting on cultural content use</title>
<p>After applying the first three coursebook use stages, two teachers began to reflect on their use of the coursebook&#x2019;s cultural content and gained a better understanding of it. The supplementary cultural content in coursebooks should be directly related to the reading text&#x2019;s cultural content and align with the students&#x2019; learning situation, rather than a broad range of supplementary materials. As two teachers&#x2019; excerpts reveal:</p>
<disp-quote>
<p>
<italic>Initially, I devote considerable time to gathering information about the text&#x2019;s cultural context. However, upon integration with the application, I observed little relevance, with only a fraction of the retrieved content proving applicable. This discrepancy prompts me to recognize the inadequacy of the search parameters. Consequently, in the subsequent data supplementation process, I refined the approach by focusing solely on retrieving materials closely linked to the cultural content of the reading text, eschewing broad searches (Alice&#x2019;s post-lesson interview and teaching plan analysis).</italic>
</p>
</disp-quote>
<disp-quote>
<p>
<italic>John stated in the interview, &#x201C;I am in favor of using cultural content of coursebooks centered on students, and that is how I use cultural content of reading texts in the process. However, I have developed the habit of teaching students additional materials related to the texts&#x2019; cultural content, which makes selecting relevant materials particularly time-consuming and energy-intensive. Gradually, I realized that as long as supplementary cultural instruction aligns with the text&#x2019;s objectives and matches students&#x2019; learning levels, a moderate amount of additional material is sufficient. Over-supplementing does not align with students&#x2019; learning situations and can lead to poor teaching outcomes, potentially achieving the opposite of the intended effect.&#x201D; (John post-lesson interview and teaching plan analysis).</italic>
</p>
</disp-quote>
<p>In addition to reflecting on strategies for using cultural content, two teachers also reflected on their classroom teaching. They flexibly adjust their teaching tasks based on students&#x2019; classroom performance and reactions, reflecting the development process from planning to implementation. For instance, during classroom instruction, students in John&#x2019;s class demonstrated insufficient text interpretation skills and an inadequate understanding of the connotations of festival values, which led to difficulties in reading comprehension, as they struggled to extract the main ideas of paragraphs and texts accurately. In response, John immediately adjusted the teaching task during class. He chose to adopt a teaching strategy of building &#x201C;scaffolding&#x201D; for students, guiding them to read the main sentences of paragraphs and prompting them to focus on the first or last sentences to answer questions, thereby helping them obtain key information to understand the text&#x2019;s cultural concepts. After class, he reflected that it would actually be possible for students to express their own opinions during the class, although it might take up more classroom time. Through the collision of thoughts from all students, the main ideas of the text and paragraphs could also ultimately be derived.</p>

<label>6.2</label>
<title>Factors influencing the use of cultural content</title>
<p>Teachers do not use curriculum materials in a vacuum. A multitude of factors shape their use of curriculum materials, including teachers&#x2019; personal knowledge of cultural content and students&#x2019; competence, features of the cultural content of the reading text, students&#x2019; issues, and contextual factors. Further elaboration on these factors, together with supporting evidence, is presented below.</p>
<sec id="sec22">
<label>6.2.1</label>
<title>Teachers&#x2019; personal knowledge of cultural content</title>
<p>In this study, teachers&#x2019; personal knowledge of cultural content influenced their use of cultural content. In the interview, both teachers mentioned that the cultural content in reading texts serves as a means of cultural knowledge, constructing a content scaffold to facilitate the achievement of cultural teaching objectives for teachers. By integrating cultural content into the teaching of linguistic knowledge, teachers advance the goals of cultural teaching while promoting language instruction.</p>
<p>Based on her understanding of the drama Hamlet, Alice decided to adopt an additive and supplementary strategy in her teaching. First, she incorporated and supplemented audiovisual materials from the Western drama Hamlet and the Peking opera The Prince&#x2019;s Revenge during the introductory session to help students intuitively experience and appreciate the distinct artistic expressions of Chinese and Western cultures. This approach helped them understand that the drama <italic>The Prince&#x2019;s Revenge</italic> in the text is a Western play presented in Chinese theatrical form, while retaining the essence of <italic>Hamlet</italic>, serving as an example of cultural integration between the East and West. Second, she introduced role-play exercises to help students grasp the ideological depth of Hamlet through character enactment.</p>
<p>John, based on his understanding and comprehension of the theme of festivals as well as his knowledge and recognition of the cultural customs and values associated with festivals across different cultures, decided to adopt a strategy of supplementing and adjusting the cultural content of coursebooks to develop his teaching plan. Specifically, he examined the historical origins and development of Halloween and the European Harvest Festival to compare the cultural practices embodied in these festivals and gain a profound understanding of their connotations. As illustrated in his interviews:</p>
<disp-quote>
<p>
<italic>In formulating and implementing the teaching plans, I used cultural knowledge in the reading texts as a basis for designing tasks and activities to advance the teaching of cultural concepts, guide students in absorbing cultural knowledge, and develop cultural literacy throughout the learning process.</italic>
</p>
</disp-quote>
<p>Moreover, John noted that the text&#x2019;s existing cultural knowledge still requires supplementary materials to fully discuss the festival&#x2019;s thematic connotations. This is because the ideological essence of festivals is abstract and embedded in their cultural symbols. Without thorough preparation of rich materials and the design of relevant questions, extracting the main ideas from the text is difficult. John conducted an additional search of the text&#x2019;s cultural content to supplement the teaching materials (teaching plan analysis).</p>
</sec>
<sec id="sec23">
<label>6.2.2</label>
<title>Knowledge of students&#x2019; competence</title>
<p>Teachers&#x2019; knowledge of students&#x2019; competence is also an important factor influencing how they utilize the cultural content of coursebooks in their teaching. The overall learning atmosphere in John&#x2019;s class was positive. Based on the core literacy requirements of English, John combined the characteristics of the reading text content, structure, and language to analyze students&#x2019; learning conditions in terms of their language ability and cultural awareness. Prior to this lesson, students had already attained proficiency in English expressions for festival introductions; however, they had not yet developed a strong ability to infer and analyze the author&#x2019;s intentions through detailed examples. Therefore, the teacher incorporated questions requiring students to identify the main ideas of paragraphs in the teaching plan, aiming to train their summarizing and generalizing abilities.</p>
<p>In the post-lesson interview, John stated that his students were familiar with the unit theme, Festivals and Celebrations. The unit text mainly draws on famous traditional festivals in China and abroad, which are closely related to students&#x2019; daily lives. However, students rarely consider <italic>why we celebrate festivals</italic>, which is quite a broad question. Therefore, it is difficult for students to generalize their personal feelings about festival culture into clear answers to the question.</p>
<p>During the interview, Alice, like John, noted that her students exhibit a strong grasp of English, active critical thinking skills, a keen interest in learning the language, and effective collaboration with instructors during daily lessons. Nonetheless, she observed a deficiency in their vocabulary, particularly regarding traditional Chinese culture and the arts, resulting in a lack of pertinent knowledge. Consequently, Alice tailored her instructional approach by curating and augmenting cultural resources pertinent to the course material to address these learning gaps.</p>
</sec>
<sec id="sec24">
<label>6.2.3</label>
<title>Features of the cultural content of reading text</title>
<p>The cultural content embedded in reading text plays a crucial role in shaping teachers&#x2019; use. In interviews, both teachers highlighted that the cultural components in reading texts are instrumental in fulfilling the cultural awareness objectives specified in the English curriculum standards. These cultural elements in reading texts serve as the primary conduit for delivering cultural instruction and facilitating the attainment of cultural awareness goals.</p>
<p>For instance, John&#x2019;s teaching plan focuses on exploring the significance of festivals. The reading text is structured around various forms of festivals, each paragraph systematically presenting distinct aspects. John strategically aligns his teaching with the text&#x2019;s core themes, which elaborate on the global prevalence of festivals, the ubiquity of harvest festivals across cultures, the evolution of traditional festival customs, the commercialization of festivals, and their integral role in social interactions. By leveraging the text&#x2019;s organizational framework, John devises instructional activities that facilitate students&#x2019; comprehension of the central theme, thereby enhancing their engagement with the cultural content.</p>
</sec>
<sec id="sec25">
<label>6.2.4</label>
<title>Students&#x2019; issues</title>
<p>Both teachers tailored their incorporation of the coursebook&#x2019;s cultural content to suit their respective classes. John, for instance, opted to remove original activities when students encountered difficulties in grasping key concepts from paragraphs and texts during reading sessions. He then transformed this approach into a teaching method that directed students to concentrate on the initial sentences, thereby enabling them to respond to questions effectively.</p>
<p>Alice, like John, adjusts her pre-designed teaching tasks as she uses the textbook&#x2019;s cultural content. Alice observed that students were having difficulty to compare and compare Chinese Peking Opera and Western drama using still images and knowledge. She changed the task to ask students to choose an option from the provided images, simplifying it, encouraging students to expand their knowledge of the subject, and fostering active participation in the classroom.</p>
</sec>
<sec id="sec26">
<label>6.2.5</label>
<title>Contextual factors</title>
<p>The educational context significantly shapes teachers&#x2019; integration of cultural content from coursebooks. In China, English coursebooks are meticulously designed in alignment with government-mandated curriculum standards. Consequently, teachers&#x2019; incorporation of cultural content closely aligns with the prescribed objectives of these coursebooks. Notably, two high school English teachers adhered strictly to the original cultural content presented in the reading passages, eschewing any modifications. Their pedagogical approach prioritized adherence to the coursebooks to ensure students&#x2019; proficiency in the requisite examinable knowledge. This study diverges from prior research by revealing that English teachers opted to enrich the existing cultural content in coursebooks through supplementary materials and adjust other cultural materials, rather than altering them.</p>

<label>7.1</label>
<title>Teachers&#x2019; flexible use of coursebooks&#x2019; cultural content</title>
<p>In using the coursebooks&#x2019; cultural content, teachers demonstrate flexible, timely adaptation. This aligns with the theoretical perspective proposed by <xref ref-type="bibr" rid="ref34">Remillard (2005)</xref>, who posited that teachers&#x2019; enactment of curriculum materials constitutes a participatory, interactive relationship. Analysis of various research data reveals that this process primarily involves four approaches: reading on and clarifying objectives, evaluating cultural content, adapting, and reflecting on cultural content use. Teachers&#x2019; use of cultural content concurs with previous research (<xref ref-type="bibr" rid="ref9001">Ball et al., 2011</xref>; <xref ref-type="bibr" rid="ref20">Li and Xu, 2020</xref>), which concludes that teachers&#x2019; enactment of materials is dynamic and interactive. In particular, two teachers adapted the material, which concurs with existing research (<xref ref-type="bibr" rid="ref3">Brown, 2009</xref>). When using cultural content, the teacher adapts the coursebook flexibly based on their understanding of it. It can be said that the coursebook&#x2019;s cultural content and teachers&#x2019; personal knowledge of cultural content influence how students perceive and teach it.</p>
<p>In addition, teachers prioritize clarifying cultural goals and take cultivating cultural awareness as the core starting point, perhaps because coursebook compilation in China primarily follows the curriculum structure and standards promulgated by the central government as guiding blueprints. This aligns with the perspective of <xref ref-type="bibr" rid="ref16">Guerrettaz and Johnston (2013)</xref>, who viewed teaching materials in ESL classrooms as embodiments of the curriculum. Conducting training sessions on the use of new coursebooks for English teachers is one way to help teachers fully understand and effectively use the cultural content of the coursebooks. Although there is no direct dialog between teachers and the compilers of the coursebook, China organized relevant training activities for teachers after the promulgation of the new coursebooks to transfer the underlying compilation philosophy to English teachers.</p>
<p>Furthermore, although the use of coursebook exhibits a degree of uniformity, teachers demonstrate considerable flexibility in their use. While advancing the curriculum objectives outlined in the course standards, two teachers adapted the cultural content of coursebooks to varying degrees. This demonstrates that, in implementing cultural awareness competency objectives, teachers have played a relatively comprehensive role in transforming the written curriculum into taught and learned curricula. In this process, teachers&#x2019; use of the coursebook&#x2019;s cultural content is guided by curriculum objectives and influenced by teaching contexts and students. To be specific, despite the coursebook&#x2019;s mandatory role, teachers demonstrated significant potential to use materials more flexibly, consistent with previous research (<xref ref-type="bibr" rid="ref45">Zhang et al., 2022</xref>; <xref ref-type="bibr" rid="ref26">Menkabu and Harwood, 2021</xref>). Generally, both teachers primarily employed two categories of usage strategies for coursebook cultural content: supplementing and adjusting, while keeping an eye on the general requirements of the English syllabus. But unlike prior research (<xref ref-type="bibr" rid="ref3">Brown, 2009</xref>; <xref ref-type="bibr" rid="ref38">Sherin and Drake, 2009</xref>), two teachers refrained from altering the coursebook&#x2019;s cultural content.</p>
</sec>
<sec id="sec29">
<label>7.2</label>
<title>Factors influencing teachers&#x2019; use of coursebooks&#x2019; cultural content</title>
<p>The study revealed that five factors influenced Chinese senior high English teachers&#x2019; use of cultural content in the coursebook. Influencing factors include teachers&#x2019; personal knowledge of cultural content and students&#x2019; competence; the features of the cultural content in the reading text; students&#x2019; issues; and contextual factors. In other words, the process of using cultural content in a coursebook has not been simple or linear. Teachers&#x2019; use of coursebooks&#x2019; cultural content is not merely a singular adherence to the prescribed material, but stems from their own cognitive understanding and interpretation of instructional cultural content. This aligns with the theoretical perspective proposed by <xref ref-type="bibr" rid="ref34">Remillard (2005)</xref>, which holds that multiple factors influence teachers&#x2019; use of curriculum materials. To be specific, the flexible strategies teachers employ in using the coursebook&#x2019;s cultural content demonstrate that its use is influenced by the textual characteristics of the content and by teachers&#x2019; understanding and knowledge of it. This aligns with previous research indicating that curriculum materials influence how teachers use them (<xref ref-type="bibr" rid="ref20">Li and Xu, 2020</xref>; <xref ref-type="bibr" rid="ref45">Zhang et al., 2022</xref>).</p>
<p>Teachers&#x2019; personal knowledge of cultural content and students&#x2019; competence are influencing factors, and the coursebook&#x2019;s cultural content use in this study reflects a &#x201C;collaboration&#x201D; between teachers and the coursebook&#x2019;s cultural elements, jointly shaping teaching strategies that align with students&#x2019; learning contexts and classroom responses. This also concurs with Brown&#x2019;s research findings (<xref ref-type="bibr" rid="ref3">Brown, 2009</xref>), indicating that during the process of using materials, the teacher has the pedagogical design capacity to perceive and mobilize existing resources to craft instructional episodes.</p>
<p>Furthermore, two teachers&#x2019; use of cultural content showed a distinctive characteristic that previous research has also paid much attention to (<xref ref-type="bibr" rid="ref32">Rathert and Cabaro&#x011F;lu, 2021</xref>; <xref ref-type="bibr" rid="ref34">Remillard, 2005</xref>). Their use of cultural content employed a student-centered approach. This approach is clearly demonstrated through the implementation of a variety of flexible usage strategies. By prioritizing students&#x2019; individual needs and backgrounds, two teachers noticed students&#x2019; reactions during classroom instruction, adjusted their learning activities accordingly, and enhanced students&#x2019; learning experience.</p>

<title>Conclusion and limitations</title>
<p>This study found that teachers emphasize cultivating cultural awareness goals in the new round of curriculum reform when using textbook cultural content, while also paying attention to students&#x2019; learning conditions, reflecting a student-centered approach to textbook use. From the research findings, it can be observed that although teachers consciously align the cultural content of teaching with curriculum objectives and strive to implement the goal of cultural awareness in their teaching practices, they pay insufficient attention to the implicit ideological connotations and value systems embedded in these materials. This results in a relatively superficial teaching of the coursebook&#x2019;s cultural content.</p>
<p>While comprehensively examining the process of implementing the cultural awareness curriculum goals in education in the latest round of English curriculum reform in China, this study effectively addressed the research questions; however, it should be noted that it is inherently small-scale, with a limited scope and a focused approach. The results have inherent limitations, as they cannot be generalized to all language teachers across contexts and educational settings. While insightful and valuable to some extent, the findings should be cautiously interpreted, recognizing that they may not reflect standard practices of all EFL cultural content teaching.</p>

<title>Implications and significance</title>
<p>The findings of this study have several implications for teachers&#x2019; professional development. To achieve the goals of educational reform, it is essential to foster teachers&#x2019; competency in using curriculum materials effectively. Competence in effectively utilizing the coursebook&#x2019;s cultural content can be fostered at the instructional and institutional levels.</p>
<p>First, for the instructional level, before using the coursebook&#x2019;s cultural content to develop a teaching plan, teachers should more consciously understand it, enriching their understanding, to help students learn it better. During this process, they should effectively utilize the course book&#x2019;s cultural content in conjunction with students&#x2019; learning situations. Teachers should continuously reflect on and summarize their teaching experiences with the coursebook&#x2019;s cultural content and students&#x2019; classroom participation. This process helps teachers continually refine their use of the coursebook, enhancing their pedagogical design abilities (<xref ref-type="bibr" rid="ref3">Brown, 2009</xref>). Second, at the institutional level, through collective lesson planning or discussion activities organized by schools and teacher preparation groups, teachers are given opportunities to communicate and engage in intellectual exchange about the use of cultural content. By participating in group discussions, teachers can gather more ideas and approaches for using cultural content. For example, the school can host discussions on key points of the cultural content during collective lesson preparation. Additionally, targeted workshops focused on cultivating cultural awareness can be organized to provide platforms for communication and discussion on developing teachers&#x2019; specialized skills during coursebook use.</p>
<p>The study is essential in two main ways. First, it helps fill a significant gap in research on language teachers&#x2019; use of cultural content in coursebooks in the material-based English Language Education (ELE) setting. Second, it introduces a new way of understanding how language teachers interact with prescribed curriculum materials. The results can serve as practical tools to help teachers make informed choices about incorporating best practices and adapting textbook content to achieve their teaching goals and address their students&#x2019; diverse needs.</p>
