在教学改革运动中,我們对立体几何的教学进行了改革。現在把我們的初步体会写在下面,请同志們指正。 1.大胆改革教材是提高效率提高質量的先决条件原教材是用公理法,以直接度量的方法推出长方体的体积计算公式,然后在这个基础上逐一地推出棱柱、棱錐和棱台的体积計算公式来。按照这个系統,讲授既費时間,学生又不易接受。因此我們用增加公理数目的办法来簡化証明。这样既节約了时間,又保証了学生的学习貭量。公理法是数学基础中的重要內容之一,高等数学中它也有重要的应用,在中学給予适当地訓练是必要
In the teaching reform movement, we have reformed the teaching of three-dimensional geometry. Now let’s write down our preliminary experience. Please ask the comrades to correct me. 1. The bold reform of textbooks is a prerequisite for improving efficiency and quality. The original textbook uses the axiom method to derive the volumetric formula of rectangular solids using a direct measurement method. Then, on this basis, the volume calculation formulae for prisms, pyramids, and prisms are introduced one by one. Come. According to this system, teaching is time-consuming and students are not easy to accept. Therefore, we simplify the proof by increasing the number of axioms. This will not only save time, but also ensure that the student’s learning capacity. The axiomatic method is one of the important contents of mathematics. It also has important applications in higher mathematics. It is necessary to give proper training in secondary schools.
