Four types of multiple classroom teaching are discussed: 1. Using instructional aids like blackboards, wall charts and pictures to maintain student interest and involve different senses to aid learning. The content and availability of materials should be considered. 2. Using questioning techniques to actively involve students, arouse curiosity, focus on concepts, and encourage students to ask questions. 3. Responding to learners by answering their questions and providing feedback. 4. Adjusting responses based on learners' needs.
