高中生如何养成良好的学习习惯
高中学习是一个系统的过程,它不像初中的课程,可以凭借小聪明在考试前 突击一下就把成绩提上去,对于难度更大、覆盖面更广的高中内容来说,预习、听课、复习、作业、笔记等等都是必不可少的环节,不但这样,还有一些习惯性的做 法需要培养。高中生如何养成良好的学习习惯,需要学校和官网共同努力。有那些好的学习习惯呢?
1.专心听课的习惯
如果课前没有一个“必须当堂掌握”的决心,会直接影响到听讲的效果,如果在每节课 前,学生都能自觉要求自己“必须当 堂掌握”,那么上课的效率一定会大大提高。实际上,有相当多的学生认为,上课听不懂没有关系,反正有书,课下可以看书。抱有这种想法的学生,听课时往往不 求甚解,或者稍遇听课障碍,就不想听了,结果浪费了上课的宝贵时间,增加了课下的学习负担,这大概正是一部分学生学习负担的重要原因。
集中 注意力听课是非常重要的,心理学告诉我们注意是心理活动对一定对象的指向和集中,它是心理过程的动力特 征。注意的指向性,可使人的心理活动在每一瞬间都能有选择的反映事物;注意的集中性,可使事物在人脑中获得清晰和深刻的反映。正因为注意拥有指向性和集中 性两个重要的特征,所以,注意具有选择、保持以及对活动的调节和监督的功能。思路就是思考问题的线索。上课听讲一定要理清思路。要把老师在讲课时运用的思 维形式、思维规律和思维方法理解清楚。目的是向老师学习如何科学地思考问题,以便使自己思维能力的发展建立在科学的基础上,使知识的领会进入更高级的境 界。分心是注意的反面,分心不是没有注意,只是没有把注意指向和集中在当前的学习任务上,心不在焉,必定“视而不见、听而不闻、食而不知其味”。
2.认真预习的习惯
很多同学只重视课堂上认真听讲,课后完成作业,而忽视课前预习,有的同学根本没有预习,其中最主要的原因不是因为没 有时间,而是因为没有认识到期预习的重要性。那么预习有什么样好处呢?课前预习也是学习的重要环节,预习可以扫除课堂学习的知识障碍,提高听课效果;还能 够复习、巩固已学的知识,最重要的是能发展学生的自学能力,减少对老师的依赖,增强独立性;预习可以加强记课堂笔记的针对性,改变学习的被动局面。在预习 时,要做到:了解教材的大概内容与前面已学的知识框架;找出本章或本课内容与前面已学知识的联系,找出所需的旧知识,并补习此时的知识;找出本课的难点和 重点(作为听课的重点);对重点问题和自己不理解的问题,用笔划或记入预习笔记。
3.独立完成作业的习惯
明确做作业是为了及时检查学习的效果,经过预习、上课、课后复习,知识究竟有没有领 会,有没有记住,记到什 么程度,知识能否应用,应用的能力有多强,这些学习效果问题,单凭自我感受是不准确的。真正懂没懂,记住没记住,会不会应用,要在做作业时通过对知识的应 用才能得到及时的检验。做作业可以加深对知识的理解和记忆;实际上,不少学生正是通过做作业,把容易混淆的概念区别开来,对事物之间的关系了解得更清楚, 公式的变换更灵活。可以说做作业促进了知识的“消化”过程,使知识的掌握进入到应用的高级阶段。做作业可以提高思维能力;面对作业中出现的问题,就会引起 积极的思考,在分析和解决问题的过程中,不仅使新学的知识得到了应用,面且得到了“思维的锻炼”,使思维能力在解答作业问题的过程中,迅速得到提高。做作 业可以为复习积累资料;作业题一般都是经过精选的,有很强的代表性、典型性。因此就是做过的习题也不应一扔了事,而应当定期进行分类整理,作为复习时的参 考资料。
