案例是数学知识内涵及内在特性有效呈现和外在反映的重要介质.一堂高质量、高效率的数学课堂教学,其“点睛之笔”和“出彩”环节应在案例教学上.本文作者结合教学实践感悟以及新课标要求,对初中数学课堂案例教学活动实施作一简要的论述. The case is an important medium for the effective presentation and external reflection of the connotation and inherent characteristics of mathematical knowledge.A high quality and efficient math classroom teaching should be put in case teaching in terms of “finishing touch” and “giving out color”. Based on the teaching practice perception and the requirements of the new curriculum standard, the author makes a brief discussion on the implementation of the case teaching activities in the mathematics classroom of junior high school.
