五一年夏于某部授数学课并编数学教材,工作中遭遇到很多问题,作过一些努力;(?)对编写初中平面几何方面摘述一些不算成熟的意见,就正于从事中等数学教育的同志们,希望大家共同讨论,俾使这些问题都能得到更好的处理。Ⅰ.初中平面几何里的材料的组织问题。我们主要地取直线形部分的材料为例。编排初中平面几何教材时,总得照顾以下两点:第一是逻辑顺序,简单浅显的在前,复杂深涩的在后;第二是内容的系统,同类的材料(注一)就尽可能予以集中。但这两
In the summer of the first year of the year, he taught mathematics classes and compiled mathematics textbooks. During the work, he encountered many problems and made some efforts. (?) Summarized some not-so-professional opinions on the preparation of junior middle school plane geometry, and he was engaged in medium-term. The comrades of mathematics education hope that we can discuss together so that these problems can be better handled. I. The organization of materials in the plane geometry of junior high school. We mainly take the material of the linear section as an example. When compiling junior middle school plane geometry textbooks, it is necessary to take care of the following two points: The first is the logical sequence, which is simple and straightforward; the second is the system of content, and the same kind of material (Note 1) is used as much as possible. concentrated. But these two
