中学数学教材是学生在中学里学习数学的主要书籍,它里面的例题、习题都是经过精选、具有一定代表性的。因此,不论在平时教学中,还是在总复习中,都必须重视课本的作用,做到“以大纲为纲,以课本为本”,大面积提高教学质量。那么,如何最大限度地发挥教材的作用呢?如何利用教材中的例题、习题来指导学生的数学学习,提高学生的探索创造能力与求知欲望呢?本人在教学中,采用了“四不妨”:即:对有些公式、结论不妨来一个追根寻源;对有些解题方法不妨来个类比使用;对有些特例不妨探寻一下一
High school mathematics textbooks are the main books for students to study mathematics in secondary schools. The examples and exercises in them are selected and representative. Therefore, whether in the ordinary teaching or in the overall review, we must attach importance to the role of textbooks, so that we can “take the outline as the guideline and take the textbook as the basis” to improve teaching quality in large areas. Then, how to maximize the use of teaching materials? How to use examples of textbooks, exercises to guide students’ mathematics learning, improve students’ exploration and creativity and desire for knowledge? I used in the teaching, “four may wish to”: That is: for some formulas, conclusions may wish to come from a root-seeking source; for some problem-solving methods may wish to use an analogy; for some special cases may wish to explore a
