在高中数学教学过程中,例题的讲解是个很重要的环节。通过例题的设计与讲解,能加深学生对知识的理解、掌握解题的方法,形成数学的基本思想。另外,通过示范例题的解题过程,也能使学生了解解题的书写格式和表述方法。学生在学习新知识的同时掌握了一定的解题方法,但是也容易形成心理定式,缺乏对知识与思想方法的再认识,造成思维僵化。因此,在高三复习的过程中,要注意对课本中的例题进行挖掘与纵横拓展,不妨变通性设计例题,一题多变,让学生能多角度、
In the mathematics teaching process of high school, the explanation of the examples is an important part. Through the design and explanation of examples, students can deepen their understanding of knowledge, master the method of solving problems, and form the basic idea of mathematics. In addition, through the problem-solving process of demonstration examples, students can also understand the writing format and presentation method of problem solving. While learning new knowledge, students master certain problem-solving methods, but they are also prone to form psychological patterns. They lack knowledge of thoughts and methods of thinking, resulting in rigid thinking. Therefore, in the process of reviewing the third year, it is necessary to pay attention to the excavation and vertical and horizontal expansion of the examples in textbooks. It may be a flexible design example, a changeable topic, so that students can be multi-angle,
