正确組織系統复习旧教材是更好地掌握教材的最重要的一个条件。在我們看来复习要符合下列的要求: 1.复习不应該和新学一样;复习用的問題不应該是千篇一律的,因为这样会养成学生墨守陈规,不思考、不钻研的坏习慣。 2.复习应該是对旧教材系統整理,概括和加深;要使学生能在已經学过的教材中,发現新的东西;找出新旧教材间的邏輯关系。 3.应該选择能发展学生数学思維的材料。使学生学会看图、讀公式并能发現它們的数学本貭。 4.应該解这样一些类型的題目:1)分解复合图形,2)加輔助綫以作出新的图形,3)把某图形割补成另外的图形(这类題目可以发展学生的构造能力)。通过多种多样的工作引起学生的兴趣,巩固地建
Correctly organizing the system to review old textbooks is the most important condition for better mastering the textbooks. It seems to us that the review should meet the following requirements: 1. The review should not be the same as the new school; the problem of review should not be stereotyped, because it will develop students who stick to stereotypes, do not think or study bad habits. used. 2. The review should be a sorting, summarizing and deepening of the old textbook system; students should be able to find new things in the textbooks they have already learned; and find out the logical relationship between the old and new textbooks. 3. Should choose materials that can develop students’ mathematical thinking. Let students learn to read pictures, read formulas, and discover their mathematical principles. 4. The following types of questions should be solved: 1) Decompose composite figures, 2) Add auxiliary lines to make new figures, 3) Cut a figure into additional figures (such questions can develop students’ constructive ability) . Through a variety of jobs to arouse the interest of students and consolidate construction
