15、边听边想。为讲明一个定理，推出一个公式，老师讲解顺序是怎样的，为什么这么安排？两个例题之间又有什么相同点和不同之处？特别要从中学习理科思维的方法，如观察、比较、分析、综合、归纳、演绎等。作为实验科学的物理、化学和生物，就要特别重视实验和观察，并在获得感性知识的基础上，进一步通过思考来掌握科学的概念和规律，等等。二、听文科课要注重在理解中记忆 文科多以记忆为主，比如政治，要注意哪些是观点，哪些是事例，哪些是用观点解释社会现象。听历史课时，首先要弄清楚本节教材的主要观点，然后，弄清教材为了说明这一观点引用了哪些史实，这些史料涉及的时间、地点、人物、事件。最后，也是关键的一环，看你是否真正弄懂观点与史料间的关系。最好还能进一步思索：这些史料能不能充分说明观点？是否还可以补充新的史料？有无相反的史料证明原观点不正确。三、听英语课要注重实践 英语课老师往往讲得不太多，在大部分的时间里，进行的师生之间、学生之间的大量语言实践练习。因此，要上好英语课，就应积极参加语言实践活动，珍惜课堂上的每一个练习机会。2022-10-22最新中小学教学课件21thank you!2022-10-22最新中小学教学课件22
