Let’s cross the bridge when we come to it. 船到桥头自然直。

? 老师上课都有一定的思路,抓住老师的思路就能取得良好的学习效果。在上一小节中已经提及听课中要跟随老师的思路,这里再进一步论述听课时如何 抓住老师的思路。
? ① 根据课堂提问抓住老师的思路。老师在讲课过程中往往会提出一些问题,有的要求回答,有的则是自问自答。一般来说,老师在课堂上提出的问 题都是学习中的关键,若能抓住老师提出的问题深入思考,就可以抓住老师的思路。
? ② 根据自己预习时理解过的逻辑结构抓住老师的思路。老师讲课在多数情况下是根据教材本身的知识结构展开的,若把自己预习时所理解过的知识 逻辑结构与老师的讲解过程进行比较,便可以抓住老师的思路。
? ③ 根据老师的提示抓住老师的思路。老师在教学中经常有一些提示用语,如“请注意”、“我再重复一遍”、“这个问题的关键是····”等等,这些 用语往往体现了老师的思路。来自:学习方法网
? ④ 紧跟老师的推导过程抓住老师的思路。老师在课堂上讲解某一结论时,一般有一个推导过程,如数学问题的来龙去脉、物理概念的抽象归纳、语 文课的分析等。感悟和理解推导过程是一个投入思维、感悟方法的过程,这有助于理解记忆结论,也有助于提高分析问题和运用知识的能力。
? ⑤ 搁置问题抓住老师的思路。碰到自己还没有完全理解老师所讲内容的时候,最好是做个记号,姑且先把这个问题放在一边,继续听老师讲后面的 内容,以免顾此失彼。来自:学习方法网
? ⑥ 利用笔记抓住老师的思路。记笔记不仅有利于理解和记忆,而且有利于抓住老师的思路。
