The document discusses two teaching methods: the type study method and the expository method. The type study method involves studying a single representative case to understand a broader topic. For example, studying the Pasig River to understand river systems. It involves selecting a typical topic, motivating students, stating the case, studying details, comparing to a model, and generalizing. The expository method is used to explain concepts to students. It involves three steps: setting up the lesson by recalling past experiences, presenting the material while relating it to students' experiences and using devices like analogies, and applying the lesson through activities to check understanding.
