Teaching, like other caring professions, is emotional. These emotions tend to emerge as teachers' goals, standards, and beliefs transact with other classroom stakeholders during everyday school activities. As such, for teachers, the classroom context involves both the extreme happiness and joy from a lesson that goes as planned to the intense frustration of working with a challenging student. These academic emotions have garnered the attention of a growing number of researchers, and will be the focus of this article. More specifically, my goal is to summarize and extend our thoughts about the nature of research and our program of research related to teacher emotion.
