近年来的中学教学工作感到在几何方面最为困难,学生的几何知识水平因而也是不高的。值得注意的是要减轻学生负担决不可从进一步精简教材上来着想。在革命前以及革命后至今的历年经验的总结基础上已经把现在的几何教材精简到最小限度的内容了。如果再度删去某些章节可能会损害教学法的基本原则:科学性原则和循序渐进的原则。
In recent years, the teaching work in middle schools has felt the most difficult in terms of geometry, and the students’ level of knowledge in geometry is therefore not high. It is worth noting that the burden on students should not be reduced from the further streamlining of textbooks. Based on the summary of the experiences of the past years before and after the revolution, the current geometry textbook has been reduced to the minimum content. The deletion of certain chapters again may undermine the basic principles of pedagogy: the principle of science and the principle of gradual and orderly progress.
