It lists 12 components: lesson plan, timetable fit, aims, assumptions, materials and resources, class profile, anticipated problems and solutions, evaluation, procedure, interaction pattern, timing, and aids. It then provides descriptions for each component to help match them correctly. The components cover questions about the learners, objectives, structure, timing, resources, and potential issues to consider when designing an effective lesson.
