例题是数学课课堂教学的一个主要内容。例题教学不仅可以让学生在掌握旧知识的基础上构建新的认知结构,而且可以通过思维能力的锤炼不断地培养学生分析问题和解决问题的能力。因此,加强例题教学的研究是当前优化数学课堂教学途径中的一个重要课题。依笔者之见,例题教学主要应从如下几方面入手: 一、直观演示,突破教学难点。
Example is a major part of mathematics classroom teaching. Example teaching not only allows students to build a new cognitive structure based on the old knowledge, but also constantly cultivates students' ability of analyzing and solving problems through the training of thinking ability. Therefore, to strengthen the study of case teaching is an important issue in the current optimization of classroom teaching of mathematics. According to the author's opinion, the teaching of examples should mainly start from the following aspects: First, visual demonstration, breakthrough teaching difficulties.
