This unit introduces reflection and its significance for teachers. Reflection is defined as systematically reviewing experiences to improve teaching and maximize student learning. It involves analyzing lessons to consider new approaches and tailor instruction to students. The benefits of reflection include improving practice, responding to issues, developing strategies, and understanding the broader context of teaching. Reflection is a cycle of teaching, self-assessing the impact on learning, considering improvements, implementing changes, and repeating the process. It allows teachers to consciously learn from experiences.
