The document discusses defective teaching and learning processes, microteaching, and its advantages. It notes that typical teaching involves more teacher talking and focusing on memory, with less student expression, explanation, and encouragement. Teaching also lacks planning, differentiation, and effective aid usage. Microteaching is then defined as a short lesson taught to a small group with immediate feedback. It aims to train teaching skills rather than content. Microteaching provides expert supervision, feedback, and the ability to reteach skills one at a time with confidence building.
