The United States is facing an unprecedented teacher shortage. With many studies estimating that 17-33% of teachers leave the profession within their first five years of starting a career, something needs to change to keep new teachers in the classroom. This study evaluates the effectiveness of peer observation as a learning tool to supplement the training of preservice teachers on an elementary campus. Observational learning theory and adult learning theory created the lens through which peer observations were implemented and evaluated in this study. Specifically, this study aimed to answer the following research questions: (a) How do conversations about teaching practices evolve over time between the preservice teacher participant and the researcher within the context of discussions following peer observations? and (b) How do peer observations influence the teaching practices of preservice teachers? This study found that the preservice teachers who participated in the peer observation intervention improved in their teaching practices over the course of the semester, valued the experience of peer observation visits, and increased their ability to talk about teaching and learning in more sophisticated and complex terms.
