深入钻研教材,是教师必备的基本功。中师数学教学应当充分利用教材教会学生如何钻研,促使学生加深对教材的理解,养成钻研教材的良好习惯,以利在日后的工作中不断学习、不断补充和提高。在教学实践中,为了引导学生钻研教材,我采用了以下几种方法: 一,设问。要求学生在自学指定教材的过程叶,每深入一步都要问一个为什么,弄清楚这一步是在什么概念上建立起来的,应用了哪一条定理、性质,为什么这样处理,等等。例如让学生自学《几何》中“两条直线夹 In-depth study of teaching materials, teachers essential basic skills. Teachers mathematics teaching should make full use of textbooks to teach students how to teach students to deepen their understanding of teaching materials, develop good habits of textbooks, in order to facilitate continuous learning in the future, continue to add and improve. In teaching practice, in order to guide students to study textbooks, I used the following methods: First, ask questions. Students are asked to specify what the step is in terms of what is the concept, what kind of theorem is applied, why and why, and so on. For example, let the students self-study “geometry” in the "two straight clip
