19、师的思路。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 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。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 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。2023-5-8最新中小学教学课件212023-5-8最新中小学教学课件22谢谢欣赏！
