在数学教学中,应着力培养学生的自学能力。常见的培养自学能力的方法之一是:在讲解新课之前,印发阅读提纲,指出阅读的重点和思考问题,给学生安排阅读和辅导的时间;在讲解新课时,先检查学生独立阅读的效果,再针对存在的疑难问题加以讲解。以初中数学三册《勾股定理》一节为例。课前印发阅读提纲,提出下列思考问题:1.勾股定理的条件是什么?结论是什么?用式子如何表示?用语言怎样叙述?2.表示勾股定理结论式子能写出几个?3.课本上证明勾股定理有几个主要步骤?(提示:参照证明过程的分段——每一
In mathematics teaching, we should cultivate students' self-learning ability. One of the common ways to cultivate self-learning ability is to print a reading syllabus before pointing out a new lesson, point out the key points of reading and thinking, and arrange the reading and counseling time for students. In explaining the new lesson, check the effect of independent reading , And then explain the problems that exist. Take junior high school mathematics three volumes “Pythagorean Theorem” section as an example. What is the condition of the Pythagorean Theorem? What is the meaning of the expression? How to express the expression? How to describe in the language? 2. The Pythagorean Theorem The conclusion formula can write a few 3. What are the main steps in proving the Pythagorean Theorem in the textbook? (Hint: refer to the subdivision of the proof process - each
