Microteaching is a teacher training technique that involves teaching a single concept for a short time to a small group of students while focusing on a specific teaching skill. The goal is to help teacher trainees learn and master teaching skills. The microteaching cycle involves planning a lesson, teaching it while applying a skill, getting feedback, re-planning based on feedback, re-teaching, and getting additional feedback to improve. This cycle can repeat multiple times until the skill is adequately mastered. Microteaching has benefits like developing teaching efficiency, focusing on teaching behaviors, and allowing increased control and feedback, but it also has limitations such as potentially reducing creativity and being time-consuming.
