初中数学课时设计的初衷是,均匀分布知识点,齐头并进,逐步提高层次。让学生在短时间内,了解各个角度的知识,同时加大平面之间的联系,这是学时和应试制度的客观要求。然而这样容易使知识无法形成系统,且不容易关联。我们的目的就是通过适度的链接,初步形成知识体系模块,便于思考把握,以下将通过几个简单例子简要说明。 Junior high school mathematics class designed the original intention is to evenly distribute knowledge points, go hand in hand, and gradually raise the level. It is an objective requirement of the time and examining system to let the students know the knowledge from all angles in a short period of time and increase the contact between the planes. However, this makes it easy to make knowledge can not form a system, and not easy to associate. Our aim is to form a knowledge system module by means of appropriate links so as to be easy to think and grasp. A few simple examples will be briefly introduced below.
