This document discusses microteaching, a teacher training technique where teachers review recordings of short teaching sessions to get feedback. Microteaching was developed in 1961 at Stanford University. It involves teaching small units of content for 5-10 minutes to small groups of students. The goals are to train new teachers and improve skills of experienced teachers. Microteaching has advantages like modifying teacher behavior, developing skills, and improving practice through individualized training and feedback. However, it only focuses on skills and may not represent normal classroom teaching.
