Editorial: Teacher Emotions Matter—Nature, Antecedents, and Effects

Along with increasing recognition of the varied aspects of education, research on teacher emotions has blossomed recently after being unacknowledged for decades. The statistics from Scopus indicate that the number of journal articles published on teacher emotions in the past 5 years is 497, comprising the largest proportion (61%) of the 812 total article corpus on the topic over the past 35 years1. Despite this notable growth, the field is still in a pre-mature developmental stage as it lacks a full consideration of the complexities of teacher emotions, and a balanced coverage of research foci and methodologies (Frenzel, 2014; Fried et al., 2015; Chen, 2019, 2020; Yin et al., 2019). In particular, Fried et al. (2015) have argued that “the study of teacher emotion is in need of conceptual clarity” (p. 415). Likewise, Chen (2019) identified a clear need for advancing mixedmethod and longitudinal studies on the topic as the existing literature on teacher emotions largely relies on self-report data and cross-sectional research designs. Although interest in the field has been growing since the first special issue by Nias (1996) in the Cambridge Journal of Education, teacher emotions have previously been addressed in only one single virtual special issue which focused on articles published in Teaching and Teacher Education by Uitto et al. (2015). The present Research Topic in Frontiers in Psychology thus aims to provide a platform for showcasing the latest research on teacher emotions, to acknowledge its increasingly important scientific impact. Inspired by the reciprocal model of teacher emotions proposed by Frenzel (2014), the current Research Topic is entitled “Teacher Emotions Matter: Nature, Antecedents, and Effects.” It was designed to spark the publication of new empirical evidence about potential reciprocal linkages between teacher emotions and other constructs, and thus contribute to the conceptual framework within the teacher emotion literature. Furthermore, this Research Topic sought to embrace a corpus of robust research covering various research foci and innovativemethodologies, aiming at maturing the evolving conceptual understanding of teacher emotions. The 16 papers which comprise this Research Topic in many ways achieve this claim, even though again, there is a predominance of cross-sectional designs and self-report-based methods of inquiry. The collection of papers consists of two parts. Part 1 explicitly covers teachers’ emotional and affective experiences, with papers one through four addressing the nature of teacher emotions, papers five through seven focusing on antecedents, papers eight and nine focusing on effects, and papers 10 and 11 focusing on reciprocal linkages. Part 2 addresses teachers’ emotion regulation and emotional competence (papers 12 through 16). Table 1 provides an overview of all 16 papers’ focal emotional variables and their

conceptualization, methodological approach, and samples. Below, we highlight key findings from each paper.
Within Part 1 of this collection of papers, which explicitly covers teachers' emotional and affective experiences, the first paper from Chen et al. examines the complexity of teacher emotions by exploring, through computational text analysis, around one million teachers' online posts from 2007 through 2018. The results evidence the multi-dimensionality characteristic of emotions, as the authors identify multiple categories of emotions and various degrees of sentiment polarity of teachers. They also emphasize the dynamic nature of teacher emotions, and report that teacher emotions vary between their workplace and their personal lives, and over time. The second paper, by Chen et al., investigates two highly experienced, award-winning teachers' trajectories of emotional experiences and their emotional labor strategies across their career, using a case-study approach. The findings demonstrate a dynamic pattern of emotions and emotional labor, as teachers transit from one career stage to another. The third paper from Cross Francis et al. focuses both on the nature of teacher emotions and on how they are managed in the act of teaching, using qualitative data from seven primary teachers in USA, asking them to report about the emotions they felt in anticipation of teaching, and during teaching retrospectively. The authors identified six emotion categories (positive, negative, neutral, blended-positive, blended-negative, and mixed), while mixed emotions (co-occurrence of positive and negative emotions) are the most dominant. The fourth paper (Tsang) takes a sociological perspective, using interview data from 21 teachers at Hong Kong secondary schools as well as policy documents and newspaper articles from the education reform era of 1980-2011, to investigate the social construction of teacher emotions by drawing on the emergent sociological concept/idea of inhabited institutionalism. The author concludes that teachers' emotions can be regarded as an interactional-institutional construction resulting from the negotiation of meaning under the institutional logics and interactions in the context of the school organizations that they inhabit.
Next, Yoo and Rho explore predictors of teacher job satisfaction via the machine learning technique Group Mnet, using data from 2,933 Korean middle school teachers and 177 principals who participated in the OECD 2013 Teaching and Learning International Survey (TALIS). The analysis of this fifth paper identifies 18 predictors of teacher satisfaction, including different school climates, teacher self-efficacy, teacher feedback, and perceived barriers to professional development. The sixth paper by Büssing et al. provides evidence on the topic-specificity of teacher enjoyment, using self-report data from 189 German biology pre-service teachers. The results show that pre-service teachers' anticipated enjoyment of teaching certain topics is differentially predicted by various values, e.g., the value of universalism predicted enjoyment for teaching about the return of wolves, and the value of benevolence predicted enjoyment for teaching about preimplantation genetic diagnosis. The seventh paper by Rinas et al. examines the relationship between achievement goals on discrete emotions, using self-report data from 439 instructors from German and Austrian universities. Results reveal that achievement goals are differentially and meaningfully associated with discrete positive and negative emotions including enjoyment, pride, anger, anxiety, shame, and boredom. For example, learning approach goals are positively related to enjoyment and negatively related to anger and boredom, while learning avoidance goals are positively related to anger.
The eighth paper, a paper by Huang et al. identifies systematic links between teacher enjoyment, anxiety and anger and teachers' engagement in informal teacher learning (learning through media, colleague interaction, stakeholder interaction, student interaction, and individual reflection), using self-report data from 2.880 primary teachers from China. The ninth paper from Rusu and Colomeischi investigates the link between the positive to negative emotion ratio and work engagement and well-being, using self-report data from 1,335 teachers from Romania. The results show teachers with a higher ratio of positive to negative emotions report more engagement and in consequence, higher levels of subjective well-being.
Based on Frenzel (2014) reciprocal model of teacher emotions, the tenth paper by Frenzel et al. identifies the relevance of goal attainment appraisals for teachers' emotions both on a between-person and a within-person level through single-and two-level multivariate multiple regression analyses, using selfreport data from 244 German secondary teachers. One of their key results is that teacher-student relationship quality attainment shows particularly strong links with teacher enjoyment, anger, and anxiety, on both levels of analysis. The eleventh paper, by Burić et al. explicitly tests the reciprocal relations between teacher emotions and self-efficacy, using self-report data from 3,010 Croatian teachers in a longitudinal study based on a full panel design with three measurement points and time lags of ∼6 months. Results show that the association between teacher emotions and self-efficacy is not bidirectional, but asymmetrical: higher levels of TSE beliefs predict higher levels of positive emotions of joy and pride, while higher levels of teachers' negative emotions of anger, exhaustion, and hopelessness predict lower levels of teachers' self-efficacy beliefs.
Furthermore, in Part 2, this collection of papers contains five papers that address teachers' emotion regulation and emotional competence. The first one of them, paper twelve, by Aldrup et al. from Germany is a methodological paper providing validation data for a newly developed situational judgment test measuring teachers' emotion regulation and relationship management capacities (Test of Regulation in and Understanding of Social Situations in Teaching: TRUST), using both in-service and pre-service teacher samples. They provide evidence of the new instrument's internal consistency, as well as its validity as teachers' emotion regulation and relationship management capacity scores show meaningful relations between teachers' emotional intelligence, Big Five personality traits, occupational well-being, and job satisfaction. The thirteenth paper by Han et al. examines the relationships between job characteristics of university teaching, emotion regulation strategies, and wellbeing using self-report data from 643 university teachers in China. Their results indicate that emotional job demands and teaching support are positively linked with university teachers' use of reappraisal strategies and well-being. In turn, suppression strategies are negatively linked with teachers' well-being. These Job satisfaction in terms of "the sense of fulfillment and gratification from working in a specific occupation"; specifically, the role and work of a teacher, as well as satisfaction with the school environment." Self-report questionnaires (OECD TALIS), cross-sectional design Emotion regulation in terms of cognitive reappraisal vs. expressive suppression and emotional exhaustion as central aspect of burnout Implicit attitude assessment for emotion regulation preference (Emotion Regulation-IAT, Mauss et al., 2006) and self-report questionnaires for emotional exhaustion (from MBI, Maslach et al., 1996) and typical emotion regulation strategy use (ERQ, Gross and John, 2003), cross-sectional design Secondary and vocational teachers, and perservice secondary teachers Chang A15. Emotion display rules, emotion regulation, and teacher burnout Emotion display rules in terms of "principles that guide us to make decisions (…) to express or not to express our emotions," Emotion regulation in terms of cognitive reappraisal vs. expressive suppression, and Teacher Burnout in terms of the composite of emotional exhaustion, depersonalization, and reduced personal accomplishment Self-report questionnaires (self-developed scale on display rules, ERQ, Gross and John, 2003, and modified teacher burnout scale by Schaufeli and Salanova, 2007) findings support the mediation role of emotion regulation, and evidence the applicability of the Job Demands-Resources model to a higher education context. The 14 paper by Donker et al. is one of the few papers within this Research Topic which moves beyond pure questionnaire-based self-report by including a computer-based implicit measure of teachers' attitudes toward emotion regulation indicating their preference for regulation over expression, in addition to self-report questionnaires for emotional exhaustion and typical emotion regulation strategy use. Sampling 94 secondary and vocational teachers, as well as preservice secondary teachers from the Netherlands, they find no direct links between teachers' implicit attitude toward emotion regulation and their emotional exhaustion or self-reported strategy use. However, teachers' implicit attitudes toward emotion regulation did moderate the relationship between the use of emotion regulation strategies and emotional exhaustion in the subsample of more experienced teachers. The fifteenth paper of this collection, Chang also addresses teachers' emotion regulation, proposing that it could function as a mediator between emotional labor and burnout as a longer-term emotional outcome. Indeed, this study could show that teachers' display rules are closely positively linked with expressive suppression, which in turn is positively linked with all three dimensions of burnout in a cohort of 561 teachers in the USA. Further, use of cognitive reappraisals is negatively associated with all three dimensions of burnout. Finally, the sixteenth paper of this collection by Zheng et al. also proposes that teacher emotional variables (here: emotional labor in terms of deep vs. surface acting) function as psychological mediators, in this case between principals' leadership behaviors and teachers' commitment. Using self-report data from a sample of 419 primary teachers from China, they could indeed show that deep acting is a positive mediator, and surface acting is a negative mediator between principals' authoritarian vs. benevolent leadership and teachers' commitment both to the profession and to the school. To sum up, the collection of papers in this Research Topic provides important findings on the complex nature and correlates of teacher emotions. It assembles 16 empirical articles sampled from nine nations namely Australia, Chinese mainland, Croatia, Germany, Hong Kong, Korea, Romania, the Netherlands, and the USA. It thus represents a truly international and inter-cultural mix of data sources and perspectives on the topic. The articles cover various, mostly impressively large samples, from primary to tertiary levels. Moreover, this collection grounds a wide range of theoretical approaches, conceptual frameworks and methods of inquiry, which allows for highly diverse and nuanced findings regarding teacher emotions as well as related emotional variables, specifically teacher emotion regulation. We hope that the contributions from this Research Topic will spark further scientific scholarly work on the topic, and inspire and serve policymakers and practitioners.
