This document discusses reflective journals for teachers. It defines reflective journals as a teacher's written response to teaching events that allows them to reflect on experiences and trigger insights. Reflective journals are used to study language learning and teacher cognition. Keeping a reflective journal involves regularly writing entries that include the date, events of the day, a focus on one or two episodes, and analysis/evaluation. Teachers can focus journal entries with reflection questions on their teaching, student behavior, and professional development. Journal data can then be analyzed for patterns and significant events.
