Background: The study of emotions in engineering education (EEE) has increased in recent years, but this emerging, multidisciplinary body of research is dispersed and not well consolidated. This paper reports on the first systematic review of EEE research and scholarship. Purpose: The review aimed to critically assess how researchers and scholars in engineering education have conceptualized emotions and how those conceptualizations have been used to frame and conduct EEE research and scholarship. Scope/Method: The systematic review followed the procedures of a configurative meta-synthesis, mapping emotion theories and concepts, research purposes and methods, and citation patterns in the EEE literature. The review proceeded through five stages: (i) scoping and database searching; (ii) abstract screening, full text sifting, and full text review; (iii) pearling; (iv) scoping review, and (v) in-depth analysis for the meta-synthesis review. Two hundred and thirteen publications were included in the final analysis. Results: The results show that the EEE literature has not extensively engaged with the wide range of conceptualizations of emotion available in the educational, psychological, and sociological literature. Further, the focus on emotion often seems to have been unintentional and of secondary importance in studies whose primary goals were to study other phenomena. Conclusions: More research adopting intentional, theorized approaches to emotions will be crucial in further developing the field. To do justice to complex emotional phenomena in teaching and learning, future EEE research will also need to engage a broader range of conceptualizations of emotion and research methods, drawing on diverse disciplinary traditions.
