初中几何知识已经不再简单形象,相对而言更加抽象,学生在学习的过程中往往会觉得更加的吃力,这是因为学生以往学习到的仅仅是数学知识,而并没有掌握正确的数学思维方式。正是因为几何知识的抽象性,所以教师在教学过程中应该注重学生数学思维的培养,几何教学中运用习题变式可以让发散自己的思维开动自己的脑筋,从而培养学生的数学思维。
Junior high school geometry knowledge is no longer a simple image, is relatively more abstract, students tend to feel more difficult in the process of learning, because students learned in the past is only mathematical knowledge, and did not master the correct mathematical thinking . It is precisely because of the abstraction of geometric knowledge, so teachers should pay attention to the cultivation of students ’mathematical thinking in the process of teaching. The use of exercises in geometry teaching can change their minds so that they can start their own brains and cultivate students’ mathematical thinking.
