The document discusses microteaching, which is a technique used to train teachers. Microteaching involves teaching a small group of students (6-10) for a short time (5-10 minutes) while focusing on one teaching skill at a time. It follows a cycle of planning, teaching, receiving feedback, re-planning, re-teaching, and getting further feedback. Some key skills practiced in microteaching are introduction, questioning, explanation, stimulus variation, and blackboard writing. Microteaching allows teachers to improve their skills in a controlled environment with immediate feedback.
