高一数学有没有学习技巧?如何高效地预习?

高中数学 08-10 浏览量: 分享:

高一数学知识点多,难度加大,不仅需要学生掌握单一的知识点,更考验学生的融会贯通,综合应用的能力。如果学习不得法,很难吃透知识点,考试受到打击,也是很正常的事情了。因此,提前预习非常有必要,高一数学到底怎么预习呢?下面是三好网小编给大家带来的高一数学高一数学预习方法,希望可以解决学生所遇到的相关问题。

 


一、明确意义是学会预习的动力源泉

学会学习是现代人的基本素质。预习意义有以下三点:1.培养良好的学习习惯。学会自主学习,掌握自学的方法,为终身学习打下基础;2.预习有助了解下一节要学习的知识点、难点,为上课扫除部分知识障碍,通过补缺,建立新旧知识间联系,从而有利于知识系统化;3.有助于提高听课效果。预习中不懂的问题,上课老师讲解这部分知识时,目标明确,态度积极,注意集中,容易将不懂问题搞懂,同时通过预习有助听课笔记的记录与使用,课本上有的内容可不记,这样挤出时间,认真听课,认真分析,提高效率。

二、读、划、写、查是预习的基本步骤:

1.读先粗读一遍,以领会教材的大意。根据学科特点,然后细读。数学课本可分为概念,规律(包括法则、定理、推论、性质、公式等)、图形、例题、习题等逐条阅读。例如,看例题时要求学生做到①分清解题步骤,指出关键所在;②弄清各步的依据,养成每步必问为什么,步步有依据的习惯;③比较同一节例题的特点,尽量去体会选例意图;④分析例题的解题规范格式,并按例题格式做练习题。

2.划即划层次、划重点。将一节内容划分成几个层次,分别标出序号。对每层中重点用★,对重点字、词下面加,对疑难问题旁边加?,对各层次间关系用=表示等等,划时要有重点,切勿面面俱到,符号太多。
 
 
 

3.写即将自己的看法、体会写在书眉或书边。

(1)写段意:每一段在书边上写出段意;(2)写小结:一要概括本书内容,二要反映本节各内容之间的并列与从属关系;(3)例题:在书边说明各主要步骤的依据,在题后空白处用符号或几个字,写出本例特点,体现编者选例意图;(4)变式:对优秀生要求对例题条件、结论变化,由特殊向一般转倾,将有关知识进行横向联系,纵向发展。

4.查即自我检查预习的效果。

①合上书本思考下节课老师要讲的内容大意,哪些内容已看懂,哪些内容模糊,哪些内容不懂,需要在什么地方再提高;②对照自学辅导或老师课前拟订的自学提纲,揭露知识的内涵,挖掘知识的本质,沟通知识的联系。简要地用语言能加以表达;③根据课本的练习,做几道具有代表性的习题,检查预习的效果。

三、处理几个关系是预习取得成效的关键

1.数学学科与其它学科的关系:预习时要花费较多的时间,高中阶段有八九门课,门门都预习不可能,可选择1-2门薄弱学科进行试点,有一定经验后再全面展开。

2.预习与听课的关系:预习是听课高效的准备,听课能解决预习中不懂的问题,可以巩固需学知识,千万不可认为预习已懂,上课不认真听讲做其他事,浪费课堂宝贵时间,影响学习效果,总之要使预习在听课中发挥最大效益,否则失去预习的作用。
