中学代数課在工農速成中学里,連續地進行了五个学期,到畢業前总复習的时候,同学們感到不少困难,这是因为:第一,代数課講的材料多,單元划分又很零乱,教材之間缺少系統性。第二,代数課內容大部分都是些抽象的定义、定理、公式、法則,缺少直观形象,因此难以巩固知識,大部分学生复習代数只是背誦一些公式,看看作業就算完事,因为复習的时候沒有把所学得的代数知識形成一个完整的系統的巩固的概念,所以过后不久就又忘記了,作業也就又發生了困难,針对这种情况,我觉得学生首先应該完整的直观地掌握代数課的主要系統,然后学生們才能够有所遵循地独立地進行全面复習。於是我繪制了一套中学代数复習圖表,对学生進行了代数課的复習展覽,下面就是关於这方面的一些体会。
The middle school algebra class was continuously implemented for five semesters in the Workers’ and Farmers’ High Schools. When they were reviewed before graduating, the students felt a lot of difficulties because: First, there are many materials in the algebra class, and the unit is very divided. Confusion, lack of systematic materials. Second, the content of algebra lessons is mostly abstract definitions, theorems, formulas, and rules. It lacks an intuitive image. Therefore, it is difficult to consolidate knowledge. Most students review algebra simply by memorizing some formulas. The concept of consolidation of the learned algebraic knowledge was not formed into a complete system, so soon afterwards it was forgotten and the operation was again difficult. In view of this situation, I felt that the students should first of all be completely intuitive. Master the main system of algebra class, and then students can conduct a comprehensive review independently and in a consistent manner. So I drew up a set of secondary school algebra review charts and conducted a review of algebra lessons for students. Here are some of the experiences in this area.
