This document discusses the use of reflective lesson plans to help improve teaching. It explains that reflective lesson plans involve writing notes after each class about what worked and how the next class could be improved. This allows the teacher to test changes and learn through a process of trial and error. The document also notes that reflective lesson plans help teachers be more efficient with their time by reducing extra activities like journals or surveys. Overall, reflective lesson plans form a continuous cycle of reflection, planning, teaching and observing that can help move teachers from novice to professional levels of practice.
