怎样有效地组织和引导学生进行数学总复习,这是广大数学教师极为关注的问题。众所周知,一堂课的前5分钟的教学情况如伺,直接影响着整堂复习课教学成败。笔者在毕业班数学复习课教学中,采用课堂前5分钟“小题”(指填空题、选择题,下同)引路,通过以解“小题”为手段来复习,收到了很好的复习效果,现介绍如下, 一、“小题”引路的必要性。 目前,对于复习课开头的5分钟,大多数教师推崇的做法都是归纳成条文或罗列成图袭来概括这一节课要复习的知识点,例如,一位教师复习“比和比例”这个知识点时,是这样引入的:同学们,今天我们复习“比和比例”这一章节,知识点提要是:
How to effectively organize and guide students in the overall review of mathematics is a matter of great concern for mathematics teachers. As we all know, the first five minutes of teaching in a class, such as watching, directly affect the success or failure of the entire review class teaching. In the graduating class mathematics review class, the author used the first 5 minutes of the class to “trove small questions” (referring to fill in the blanks, multiple choice questions, the same below) to guide the way and to review them by solving the “small questions” as a means to receive a good review. The results are as follows: 1. The necessity of the “small topic” approach. At present, for the first 5 minutes of the review class, most teachers adore the practice is summarized as a clause or listed as a map to summarize the knowledge points to be reviewed in this lesson, for example, a teacher review the “ratio and proportion” When it came to knowledge, it was introduced in this way: Students, today we review the chapter of “ratio and proportion”. The main points of knowledge are:
