Emotions such as pleasure, anger, and sadness are innate in human being, which means it is regular for psychological and social actions of people to be influenced by emotions, and education is no exception (Ge et al., 2019). Emotions are at the center of language education, and within previous decades, there is an emergent attentiveness in emotion inquiries in language teaching (Dewaele et al., 2019; Dewaele and Li, 2020). Emotions can affect learning on the whole (Pekrun et al., 2002), and language learning particularly (MacIntyre and Gregersen, 2012). Although emotions are particular, multifarious, and challenging to understand, they are important in boosting influential teaching and learning (Shao et al., 2019). The position of emotions in language education has been significantly renowned by scholars (Saito et al., 2018; Bigelow, 2019), but it has relatively received little consideration in language learning (MacIntyre, 2002; Dewaele, 2015) due to the fact that a growing concentration on emotions in teaching has lately appeared in the research literature, considering this investigation domain from different perceptions or methods that have generated supportive perceptions into the active, complex, and sophisticated nature of human emotions (Agudo, 2018). Moreover, another considerable justification of the ignorance of emotions is that they are innately very personal and irrational, and accordingly, they are neither simply visible nor assessable (Ross, 2015). While several scholars accredited the significant function of emotion in the language process (e.g., Dewaele, 2005; Swain, 2013), investigations of emotion and language learning are dropping back the swiftly developing arena of emotion in psychology and learning (Goetz et al., 2010; Pekrun et al., 2019). Concerning the issue, Benesch (2012) pinpointed that emotions have been undoubtedly disregarded in the literature because they have been hard to capture.

It is just about the previous four decades that emotions have concentrated principally on negative emotions such as anxiety (Daubney et al., 2017) and boredom in language learning (Pawlak et al., 2020; Derakhshan et al., 2021; Zawodniak et al., 2021), and it is approved that students experience a massive collection of different emotions all through their learning development (Mercer and Kostoulas, 2018; Li, 2020; Zhang and Tsung, 2021). Emotions are not only a cogent activity but also a societal one that occurs in individuals meeting in a societal context, in which feelings affect the educational experience of teachers and their reaction to the involvement of education and learning (Dörnyei, 2005). Applied linguists may have undervalued the applicability of feelings lately, owing to the power of intellectual and the untruthful belief that reviewing emotion is someway unsystematic (Sharwood Smith, 2017).

Undoubtedly, the condition has reformed with the arrival of positive psychology (PP) as researchers stimulated by the PP movement have stated that not all types of emotions are negative, and they have attempted to boost eudemonic well-being (Ergün and Dewaele, 2021), so the consideration of scholars in the language education, instructors and teachers have been moved into positive emotions (MacIntyre and Mercer, 2014; MacIntyre et al., 2016). The launch of PP in language education has developed indulgent of the array of emotions, educators and students confronted and predominantly the function that positive emotions can perform in helping education (Dewaele and Alfawzan, 2018; Dewaele and Li, 2020; Wang et al., 2021), subsequently, emotions have a central role in education progression and success (Derakhshan et al., 2020; Li, 2020).

Both students and teachers similarly encounter various kinds of emotions alternating from constructive to destructive ones (King and Chen, 2019). In fact, Fried et al. (2015) declared that studies in the emotion realm have frequently concentrated on the emotions of students on the one hand. Emotions inspire the awareness of learners and activate the learning route that governs what is achieved and what is recalled. Several studies in different realms such as neuroscience, teaching, and psychology have demonstrated that emotions are dominant in education (Seli et al., 2016; Tyng et al., 2017). On the other hand, above and beyond the prominence of emotions in the learning, it is viewed as the central element of operational education (Hosotani and Imai-Matsumura, 2011) and an essential element of teaching quality (Day and Qing, 2009; Hosotani and Imai-Matsumura, 2011), and a large body of investigations in recent times have focused on the emotions of teachers, as well (Keller et al., 2014; Taxer and Frenzel, 2015).

Emotions, for students, have been defined as the dynamic powers of inspiration and enthusiasm in education (Dörnyei, 2005). White (2018) pinpointed that positive emotion in this field functions to boost the capability of being conscious of and notify things in the situation and increase mindfulness of language materials. Other scholars (e.g., Fredrickson and Losada, 2005; Dewaele et al., 2017) maintained that progressive emotions inspire interest, willingness to communicate, and support self-directed learning educational achievement, while lack of success may provoke lots of diverse emotions in learners, which consequently may influence their presentation and manage their forthcoming guidelines (Pekrun and Perry, 2014).

In addition, teachers play a significant role in EFL classrooms in providing materials to learners, observing their progress, organizing interaction among learners, providing feedback, and evaluating their success (Derakhshan et al., 2019; Pishghadam et al., 2021a). However, the place of teacher in the language process is more than that as they are responsible for handling the emotive sense of the classroom, building a constructive setting in the language learning classes, making social rapports among classmates, and preferably, instruction with pleasure, and confidence (Dewaele, 2018). Regardless of the anger and apprehension that teachers occasionally had in the classroom, for most individuals, teaching is regarded as a foundation of positive emotions, and these support their attentiveness for teaching within the classroom (Richards, 2020). Indeed, inquiries have indicated that while in the classroom, teachers undergo different emotions, for example, pleasure, burnout, superiority, anger, frustration, and apprehension (Chang, 2009; Frenzel et al., 2009; Sutton and Harper, 2009; Beilock et al., 2010; Fathi et al., 2021). The emotions of educators can form their perception, enthusiasm, and interactions with learners (Sutton and Wheatley, 2003); influence teaching efficacy, well-being, and work engagement of teachers regarding intellectual and motivational encouragement, classroom supervision, and support, that result in the success and accomplishment of learners (Frenzel et al., 2009; Greenier et al., 2021). Hagenauer and Volet (2014), and it plays a vital role in shaping the sense of proficient characteristics, assurance, success, and well-being of educators (Day and Qing, 2009; Li et al., 2019). Additionally, there is a significant correlation between the emotions of educators and learners as learners are regularly conscious and inclined by the emotions of instructors (Postareff and Lindblom-Ylänne, 2011).

The foremost roles of both positive and negative kinds of emotions that exist in language education have been discriminated as “broadening” and “narrowing” (MacIntyre and Gregersen, 2012; Dewaele and MacIntyre, 2014), academically based on the “Broaden-and-Build Theory” (Fredrickson, 2003). In Fredrickson’s theory, she discriminates the roles of both types of emotions, asserting that the positive types can expand temporary thought-action collections of societies and shape their permanent individual foundations, fluctuating from behavioral and academic bases to societal and emotional properties, while negative ones are reversed, triggering simple persistence manners. Likewise, the other theory in this regard is the “Control-Value Theory” defining that human affection is utilized to differentiate kinds of emotions, that is to say, valence (pleasant vs. unpleasant) and activation (stimulating vs. disengaging). The control value theory perceives emotions as ranges of interconnected emotional developments, by which emotional, intellectual, motivational, and physical mechanisms are at prominence. This theory arranges for an integrative method for scrutinizing several types of emotions experienced in achievement settings, containing academic situations along with achievement circumstances in other life realms (Ismail, 2015).

Using these proportions concentrates four extensive sets of emotions: positive stimulating (e.g., satisfaction, confidence), positive motivating (e.g., enjoyment, comfort), negative motivating (e.g., nervousness, embarrassment), and destructive aspects (e.g., tediousness, boredom) (Pekrun et al., 2017). The theory suggests that these emotions impact intellectual bases, enthusiasm to study, and use of learning approaches of learners, and techniques and consequently affecting their success (Pekrun and Linnenbink-Garcia, 2012).

To sum up, the emotions of students have been deliberated recurrently in the literature (Gkonou et al., 2020), while the emotions of teachers have stayed in the shades of study and theory. It is frequently supposed that the educators are the utmost significant figures on the academic prospect (Pishghadam et al., 2021a), and their role to a large degree regulates the final achievement of both scholars and the teaching organization (Mercer and Dörnyei, 2020). However, to the best of the information of a researcher, the way both learners and their teachers react to emotions should be taken into account as it seems that they may impact the teaching of students in ways that may afterward turn into their intellectual growth. Consequently, extending the information on emotions undergone in the classroom by both teachers and learners is worth investigating on the one hand and their effects on language success and achievement on the other hand.

Emotions can impact an individual in determining to study a language and to do activities in a classroom (Méndez Lopez and Pea Aguilar, 2013) and they added that both types of emotions, namely positive and negative, can have noteworthy effects on the enthusiasm of students. They declared that negative feelings such as anxiety and depression can boost learning, and they can also be regarded as constructive in the procedure of language education. Benesch (2017) preserved that language courses are incorporating both destructive and constructive emotions; the former hindering effective education and the latter nurturing them. Additionally, due to the interactional nature of the educator-learners relationship, they entail the incorporation of individually significant content and distinctiveness, which are simplified through relation of teachers and emotive considerations of students (Xie and Derakhshan, 2021).

The existing review of literature has acknowledged the function of emotions of teachers concerning various features of learning, namely teacher, education, learner, and scholarship. Primarily, it is extensively documented that emotion of teachers influences their teaching. The emotion of a teacher interweaves with the intellect of educators and impetus that is correlated with their teaching manners (Uitto et al., 2015). It is acknowledged that the emotion of a teacher impacts numerous facets of the perceptive procedures of teachers. For instance, they can stimulus their consideration, recall, and thoughtfulness (Golombek and Doran, 2014). In addition, other results demonstrated that the emotion of a teacher is connected to other features such as teacher identity, helplessness, individual and professional lives, and well-being (Schutz and Zembylas, 2009; Kelchtermans, 2011; Lee et al., 2013; Yin et al., 2017; Greenier et al., 2021). Certainly, emotions had a momentous effect on teacher growth in the instruction career (Fried et al., 2015). Furthermore, studies also have proved that emotions of teachers influence many parts of time of students in the class together with feelings of learners, learner-teacher relationships, engagement, stress, and enthusiasm (Becker et al., 2014; Van Uden et al., 2014; Fathi and Derakhshan, 2019; Kruk, 2021; Wang and Derakhshan, 2021).

Empirical studies specified that the rapport between educators and learners is a perilous “emotive filter” (Zembylas, 2014). Nevertheless, it is suggested that educators want proper maintenance to progress a noble learner-teacher rapport in which a range of emotive determinations is restricted (Newberry, 2010). It is believed that educators with destructive feelings are prone to diminish the probabilities that learners will employ a higher degree of intellectual learning methods (Linnenbrink-Garcia and Pekrun, 2011). Teaching spaces that determine constructive emotions are more about generating a superior educational atmosphere that preserves the success and development of learners (Yan et al., 2011; Pishghadam et al., 2021b).

The arrival of PP in language education and the specific domain of feeling and language learning resonates with a difference in attitude among language specialists, moving from a destructive concentration to a more positive, adjusted methodology for examining language education. PP is considered to be an interesting theme to bring into the investigation of feelings and language learning since it incorporates aspects like positive foundations, attributes, and emotions, all of which are among essential pertinence to the assessment and development of advantageous effective encounters in language classes. The review introduced in this study stresses the requirement for the investigation of feelings to have a more focal situation in principle, exploration, and practice in language learning. While the comprehension and administration of feelings are significant components of information and capacity of an educator, for students, feelings are significant in terms of how they explore and process their education. The present paper can familiarize language scholars, experts, teachers, and students with the main values of emotions and their use in language education.

The present review has significant implications for language instruction as well future inquiries in second language acquisition (SLA) research. The organization of emotions is a central element of awareness and capability of a teacher, while for students, they are fundamental to how they direct and develop their education. In the language setting, developing positive emotions and reducing negative feelings of both educators and students could enhance inspiration, engagement, and achievement.

Learners inclined to positive emotions might encounter undeniable degrees of accomplishment mostly in light of the fact that such feelings are related to high-quality connections with friends and educators. Presently, the emotion of an educator is considered as a crucial research focus for several reasons that assume a critical and essential part in language learning and the well-being of learners (Fried et al., 2015). At present, educators are established to practice more negative than positive emotions (Thompson, 2014; Hassard et al., 2016) and educators have hurt from the same problematic and challenging issues that have been even worse recently (Yang et al., 2019). The emotion of a teacher has been acknowledged to affect the passionate situation in a classroom; thanks to its effects on learner-educator communications and teaching space manners (Schroeder, 2006). This burden has not facilitated the prevailing emotive state of educators (Thompson, 2014). In the same vein, the emotions of teachers affect their individual and proficient lives and eventually govern teacher efficiency (Schutz and Zembylas, 2009). Similarly, it can be asserted that the nature of education learners receive is likewise impacted by the feelings of their educators. Scholastic quality is worse among educators who show negative feelings and disappointment in instructing as opposed to those who exhibit more constructive emotions (Frenzel et al., 2011; Postareff and Lindblom-Ylänne, 2011). First, regardless of whether positive or negative, the feelings of educators have a specific impact on their enthusiasm (Sutton and Wheatley, 2003). Positive emotions are a significant, but not an entirely enveloping, component of intrinsic motivation. Notwithstanding, the intrinsic motivational level of the educator is often lowered by negative emotions (Sutton and Wheatley, 2003). Second, the teaching approach is closely connected to the accomplishment of education of learners, which is firmly identified with the feelings of the educator (Mohammadjani and Tonkaboni, 2015).

The underlying empirical proof created in this review paper is delivering new thoughts, information, and experiences for L2 emotion researchers (Lee, 2014) and suggesting useful proposals for educators (Shao et al., 2019). The new advancement of investigations on emotions in psychology and teaching gives L2 teachers invigorating potential outcomes. Concerning language educators, they are prescribed to acquire information on psychology and get to know the significant ideas and segments of feelings of educators and to attempt to show their insight in their practice and states of mind and to invigorate the improvement of perspectives of students on the accomplishment of educators in the language classes. Furthermore, by teaching to determine personal aims, educators can motivate learners. They can urge students to attain self-satisfaction in completing an assignment effectively. The educators can practice making light of the negative emotions, since it is perilous to concentrate a lot on negative emotions because showing such impeding factors in the classes will have a bad effect on some learners. The incorporation of emotion paradigms into the language learning field not only helps to control current shortfalls in language inquiries, for example, procedural matters and assessment difficulties, but also to provide new chances for the research populations of learning and psychology.

Regarding the language learners, they are recommended to concentrate on their emotions of educators and captivate the types of emotions, namely, pleasure in the educational field and a sensation of pleasure, and do not allow the destructive emotions to impact their fulfillment of learning a language and comprehend the ways wherein they are pursuing to grasp their scholastic proficiencies and for teachers especially to disclose the method in which students follow their language learning capabilities in the educational setting.

Syllabus designers should think through employing teaching techniques and strategies and utilizing mediation tasks and activities that nurture opinions of control of learners on their learning package to uphold their success both through increasing views of control, and by enlightening positive feelings and decreasing negative ones (Hamm et al., 2017). They are supposed to plan tasks based on desires, emotional states, and well-being of students that focus on the roles of emotions of educators and how the learners deduce their feelings, and the special effects of opinions of learners in the educational process. Since it is believed that achievement from emotion investigation in psychology and learning knowledge can support fundamental awareness into language achievement. It may function as a new stimulus in language education to plan further research for inspecting the emotive features of success.

Finally, future scholars can conduct some research incorporating the views of diverse participants in this respect; therefore, enthusiastic researchers are suggested to study these constructs regarding other factors such as optimism, pleasure, engagement, and social behaviors such as intelligibility, credibility, and immediacy (Derakhshan, 2021). In particular, some empirical studies embedded in the theoretical rational aforementioned can be done to add the fresh and nutritious food to the emotional studies of SLA. As has been indicated, emotional factors in language education have not been equally investigated (Wang et al., 2021). In view of this, it is advocated that EFL teachers of the globe and applied linguists should put their effort into doing the related studies to flourish the emotional studies. Aside from this, a large body of research is quantitative rather than qualitative studies. The main reason for this may be due to the fact that it is less challenging for language educators to collect their research data. As is known, it is pretty time-consuming to collect and codify the interview protocols as well as reflective journals. Therefore, it is suggested that more qualitative studies be conducted in the near future. Last but not least, cross-cultural or cross-national studies should also be done because the variables of emotion-based education will, to some great extent, be influenced by the identity of participants.
