最近,我们在中曹学区小学数学教研活动中听了两节比武课,其中一节是三年级上册的《可能性》,另一节是一年级上册的《分类》。这两节课有一个共性,都是实验操作课,都需要学生用大部分时间动手实验操作。这两节课,反映了这类课教学的一些普遍问题。剖析这两节课,有几个关系值得老师们探讨。希望我们的数学老师,特别是年轻教师,在实验操作课中正确处理以下几个关系。一、成熟课与挑战课成熟课,是指那些课被许多专家和教师所演绎,已经成为了经典的课例。今天的这两节课应该都是成熟课。在我们的心中,这些课已经形成了基本的教学套
Recently, we heard two martial arts classes in the mathematics teaching and research activities of the Cao Xue District Primary School, one of which is the “Possibility” of the third grade, and the other is the “classification” of the first grade. There is a commonality between the two classes, all of which are experimental operations, which require students to spend most of their time experimenting. These two classes reflect some of the common problems in the teaching of these classes. Analysis of these two classes, there are several relationships worthy of discussion. We hope that our math teachers, especially young teachers, will correctly handle the following relationships in the experimental course. First, mature class and challenge class Mature class, refers to those classes are many experts and teachers deduced, has become a classic lesson. Today, these two classes should all be mature classes. In our hearts, these classes have formed the basic teaching set
