Early childhood and elementary preservice teachers often fear mathematics, find it irrelevant, have mathematics anxiety, hold negative self-perceptions, and have low mathematics achievement. This study investigates the influence of an identity exploration intervention on preservice teachers' mathematics identities during a college Algebra course specifically designed for education majors. Results provide insight into the patterns of change in identity and motivation. Data was analyzed following a theoretical framework on role identity that highlights the interaction between self-perceptions, beliefs, goals, and action possibilities. Analysis identified patterns of change in student identities. Themes across cases highlight the differences in change amongst participants, the influence of initial identity, and the impact of perceived relevance on identity exploration.
