Emotion research in teaching and education more generally is a well-developed field of inquiry, offering suggestions for initial teacher education course development and practical suggestions for improving the working lives of teachers and schoolchildren. In contrast, emotion research in teacher education is an emergent and expanding area of inquiry. Preservice teachers, or university teacher education students, have unique emotional demands given that their teacher identities may still be in formative stages and their school-based practicum may not present the full complement of emotional experiences that full-time teachers encounter daily and for extended periods of time. Some specific objectives of past research in teacher education include explorations of preservice teachers’ emotions; preparing preservice teachers for the emotional demands of the job; developing understandings about the interplay between teacher–student relationships or social bonds, emotions, and learning; and addressing the strong emotions associated with practicum for preservice teachers, school-based teacher educators, and university-based teacher educators. A diverse range of theories are available for investigating emotion in preservice teacher education. This range presents different ways of conceptualizing what emotions are considered to be, stemming from disciplines including sociology, philosophy, psychology, critical studies, cultural studies, anthropology, and neuroscience. In addition to canvassing theories and traditions, dominant approaches to the study of preservice teacher emotions are addressed including early investigations, which relied on single self-report research methods to the more complex and dynamic multimethod and multitheoretical studies that have emerged in recent years. Suggestions are made for fruitful future lines of inquiry of preservice teachers’ emotional experiences and needs. Teacher attrition and burnout, particularly in the early years, continue to be vexing international problems. Research into preservice teacher emotions and emotion management are two important areas of inquiry that could address the related problems of burnout and attrition. Emotion management is also linked to social bonds, and better understandings of these connections are needed in the context of preservice teachers’ experiences and learning during practicums and within university courses. A focus on enacted classroom and staffroom interactions offers great scope for novel research contributions. Better understandings of structural conditions affecting emotions and preservice teachers’ learning are needed that include the bridging of macrosocial structural factors influencing work conditions with microsocial interactions in classrooms, staffrooms, and during parent-teacher interactions. New research adopting contemporary theories of emotion and methods is needed to explore preservice teacher identities. Combining this focus with the aforementioned lines of investigation into burnout, attrition, social bonds, and connections between macrostructural and microinteractional aspects of teaching and learning presents a third line of novel research. Guiding questions to prompt these and other lines of investigation are offered.
