Good teaching does not just happen during classroom instruction. The instructional design practices teachers participate in outside of instruction can have impact on potential learning opportunities that take place during class time. Lesson planning is one of those practices that can improve a teacher’s instruction; however, it needs to be supported. Although there are a plethora of lesson plan models to assist teachers, there are no concrete strategies to help principals, teacher educators and mentors give constructive feedback on lesson plans that can impact teachers’ content, pedagogy or classroom management. This book addresses it, and provides specific strategies that supervisors can use. The goal is to use lesson plans as an educative tool.
