18、在课堂上标出来，下课时，在老师还未离开教室的时候，要主动请老师讲解清楚。如果老师已经离开教室，也可以向同学请教，及时消除疑难问题。做到当堂知识，当堂解决。二、补笔记 上课时，如果有些东西没有记下来，不要因为惦记着漏了的笔记而影响记下面的内容，可以在笔记本上留下一定的空间。下课后，再从头到尾阅读一遍自己写的笔记，既可以起到复习的作用，又可以检查笔记中的遗漏和错误。遗漏之处要补全，错别字要纠正，过于潦草的字要写清楚。同时，将自己对讲课内容的理解、自己的收获和感想，用自己的话写在笔记本的空白处。这样，可以使笔记变的更加完整、充实。三、课后“静思2分钟”大有学问 我们还要注意课后的及时思考。利用课间休息时间，在心中快速把刚才上课时刚讲过的一些关键思路理一遍，把老师讲解的题目从题意到解答整个过程详细审视一遍，这样，不仅可以加深知识的理解和记忆，还可以轻而易举地掌握一些关键的解题技巧。所以，2分钟的课后静思等于同一学科知识的课后复习30分钟。2022-11-7精选最新中小学教学课件thank you!2022-11-7精选最新中小学教学课件
