复习課的教学是根据复习的目的来决定的。一般來說,复习的目的是使学生系統而牢固的掌握已学过的知識;同吋适当的加深对知識的理解提高解題能力,也就是說一方面要学生巩固已經学过的概念如定义公理、定理、公式;另一方面要加强学生的应用能力。但是采取怎样的复习方式,才能在有限的时間內发揮复习课最大的效果,这是一个值得研究的問題。过去我們会采用了首先对基础知識作系統的归納、概括,然后再安排一些有关的范例。当然,这种方法在形式上是无可非議的。因为沒有概括就难以使学生把所学过的知識系統化;沒有范例的讲解,就难以巩固已学过的知識及提高学生的解題能力。但是这种方法的前半部往往不受学生欢迎,有时甚至觉得枯燥乏味,以致学生的思想不易集中从而印象不深。根据我在教学实践中的摸索,我认为通过典型的范例来概括基础知識,不仅是可能,而且是行之有效的。如果我們有意義地通过典型范例来复习基本概 The teaching of the review class is based on the purpose of the review. In general, the purpose of the review is to enable students to systematically and firmly master the knowledge they have learned; to improve the problem-solving abilities by properly deepening the understanding of knowledge, that is, to consolidate the concepts that have been learned, such as the definition of axioms, on the one hand. , theorems, and formulas; on the other hand, students’ application ability must be strengthened. However, what kind of review methods can be used to achieve the maximum effect of the review class within a limited period of time is a question worthy of study. In the past, we used the first systematic induction and generalization of basic knowledge, and then arranged some relevant examples. Of course, this method is formally irreproachable. Because there is no generalization, it is difficult for students to systematize what they have learned; without the paradigm explanation, it is difficult to consolidate the knowledge that has been learned and to improve students’ ability to solve problems. However, the first half of this method is often not welcomed by students, and sometimes even boring, so that the students’ thoughts are not easy to focus and the impression is not deep. Based on my explorations in teaching practice, I think that summarizing the basic knowledge through typical examples is not only possible but also effective. If we meaningfully review the basics through typical examples
