This document discusses concept teaching, which refers to teaching specific concepts, the nature of concepts, and developing logical reasoning. There are two approaches to concept teaching - inductive and deductive. The inductive approach presents examples first before broader generalizations, while the deductive approach works from general theories to specific examples. Both approaches proceed through four primary phases: clarifying goals, illustrating examples, having students provide their own examples, and guiding self-reflection. The document provides guidance on selecting a concept and approach and engaging students throughout the process.
