The document discusses the definition and purpose of a lesson plan. It defines a lesson plan as a statement of the achievements and means to attain them through daily activities guided by the teacher. This shows a change in emphasis from knowledge as an end to lessons as a means to acquire habits, attitudes, and skills for personal and social development. The focus is now on the child and their activities rather than just the subject matter, with the teacher serving as a guide in the background. A lesson plan provides a detailed description of the individual lessons a teacher plans to teach on a given day to guide instruction.
