Microteaching involves teaching short lessons (5-7 minutes) to small groups of students (6-10) to practice and improve teaching skills. The microteaching cycle includes planning a micro lesson, teaching it, receiving peer feedback, revising the lesson, reteaching to another group, and getting additional feedback. This allows pre-service and in-service teachers to develop skills like introducing topics, questioning techniques, explanations, and engaging students. Microteaching helps teachers identify strengths and weaknesses to continuously improve their teaching abilities.
