由一本20世纪20年代的中国初中平面几何教材引发的思考

Thinking on A Plane Geometry Textbook for Junior High Schools in the 20’s of the Last Century

一本20世纪20年代的中国初中平面几何教材具有以下特点：开门见山、直入主题，语言简洁明了；逻辑严密，注重内容的系统性；体现理论和实际相结合；适当体现“数”与“量”、“动”与“静”的结合。从这些特点出发，引发我们进行以下思考：1．教学方法的选择影响到教材的实施；2．教材的变化要结合时代背景，考虑实施对象；3．要在传承的基础上发展教材。

Based on the analysis of a plane geometry textbooks for junior high schools of China in the 20＇s of the last century in detail, we find that they are characterized by the concise and clear language, the rigorous logic, the systemic content and the suitably combination of theory and practice, etc. From these, the article puts forward three points about mathematics textbook writing and design. First, the selection of the teaching methods may influence the implementation of the textbooks; second, the change of the textbook should refer to the background of the times and the students; lastly, we should carry through the change of the textbook based on the thoroughly experiment.
