例题教学是数学学习链中一个不可或缺的环节,缺少这一环节,学生将只能获得一堆零碎、杂乱、干瘪的数学知识,难以建构知识体系,解决数学问题.基于此,我们对教材中部分习题的教学过程进行了重点研究,充分认识课本习题的作用,挖掘习题中潜在的教学资源,发展学生的数学思维.现以《苏科版数学七年级下册》29页例2的教学为例,展示部分流程.1.第一次教学本节课的基本内容是:《苏科版数学七年级下册》第七章
Example teaching is an indispensable link in the chain of mathematics learning. Without this link, students will only get a bunch of piecemeal, cluttered and shriveled maths, which will make it difficult to construct a knowledge system and solve math problems. Based on this, Part of the exercises in the process of focusing on the study, fully aware of the role of textbook exercises, mining exercises in the potential of teaching resources, the development of mathematical thinking of students.Currently “Su Ke edition of Mathematics, Volume VII,” 29 cases of teaching 2 As an example, show part of the process .1. The first teaching The basic content of this lesson is: “Su Ke edition of Mathematics seventh grade” Chapter VII
