一、进行预习指导的缘由1.预则立,不预则废预习是学好数学的有效渠道,为培养学生的自主学习能力,发散思维,增强学生的自信心提供了理想的途径。2.从学情出发现在的教学中,大部分老师知识基于表面,不做思索地阅读教材,简单地做几个书后练习题的现象比较多,造成学生习惯性记住书本中的结论,探索形成结论的过程实在太少。学生随便打开书看一看,走马观花,预习完毕。这样的预习对学习新课没有多少用处。所以教师必须学会预习 First, the reasons for the preview guide 1. Pre-rule, not pre-waste pre-learning is an effective channel to learn mathematics, to develop students ’ability to learn independently, divergent thinking, and enhance students’ self-confidence provides an ideal way. 2. Learning from the conditions of the present teaching, most of the teachers based on the surface of the knowledge, without thinking to read the textbook, simply do a few book exercises after the phenomenon more, causing students to habitually remember the conclusions of the book to explore The process of forming a conclusion is too small. Students just open the book to see, cursory, preview is completed. Such a preview is not useful for learning a new lesson. So teachers must learn to preview
