The document discusses various skills involved in effective teaching such as introducing a lesson, using teaching aids, questioning techniques, reinforcement, stimulus variation, and illustration. It describes the components and best practices for each skill. For example, it states that introducing a lesson should include securing attention, assessing motivation, and linking to past experiences. Reinforcement involves both positive reinforcement for correct responses as well as addressing incorrect responses. Microteaching allows pre-service teachers to develop these skills in a structured yet reduced-complexity environment compared to a full classroom.
