First, the guiding ideology and theoretical basis Energy concept is the core concept of the concept of chemistry, is a general understanding of all kinds of energy and the law of transformation, the difference of energy is an important reason for the form of material existence and mutual transformation . At present, there is a more unified understanding of the teaching of concept construction that internalization of the basic connotation of the core concepts in the development of knowledge analysis, analysis of academic situation, teaching objectives, and explicit use of teaching design and teaching strategies make teachers clear A teaching session is designed to help students translate specific conceptual knowledge into a student's chemistry.
