一、创设情境,激发兴趣兴趣是最好的老师。浓厚的学习兴趣,能有效地诱发学习动机,促进学生自觉地集中注意力,全身心的投入学习活动中去探索,去发现,让学生从中体验到成功的喜悦和快乐。特别是对于那些后进生而言,习题课一定注意不能磨掉他们的兴趣。二、重现知识形成的过程,培养学生用数学的意识数学概念和数学规律大多数是由实际问题抽象出来的,因而在进行数学概念和数学规律的教学中,我们不应当只是单纯地向学生传授知识,而忽视对其原型的分析和抽象。在七年级下册的最后一章体 First, create the situation, to stimulate interest is the best teacher interest. Strong interest in learning, can effectively induce motivation to learn, to promote students to consciously focus their attention and devoted themselves to learning activities to explore, to discover, let students experience the joy and joy of success. In particular, for those backward students, the exercise class must be careful not to obliterate their interests. Second, to reproduce the process of knowledge formation, training students to use mathematical concepts and mathematical laws of mathematics most of the rules are abstracted from the actual problems, and therefore in the teaching of mathematical concepts and mathematical laws, we should not simply to the students Impart knowledge, ignoring the analysis and abstraction of its prototypes. In the seventh grade the last chapter volume
