1、如何正确进行初中物理复习课的教学单位：江苏省淮安市淮安区茭陵乡初级中学。邮编：223001 姓名：王伟华摘要：复习是教学中的一个重要环节，在平时的教学中，常会发现部分学生新课教学时掌握得还可以，但是一到复习时，好多平时强调的注意点都忘了没有复习到位，复习课效率不高。尤其是九年级老师要有效地开展中考复习工作，复习时既要掌握基础知识和基本概念，又要梳理初中物理知识结构，找出知识点之间的内在联系，形成一个由点到面的知识结构。使整个复习具有系统性、综合性、实效性。因此，如何全面地、高效地提高物理复习课的效率？是我们每一位物理教师值得探讨的话题。我国古代教育家孔子说：“学而时习之，不亦悦乎。”就是说“学

2、”需要时时温习。复习的意义，不仅仅是为了巩固知识，还有其积极的意义，“温故而知新”反映了复习的积极意义。因此复习不是简单的重复而是一个知新的过程，复习课尤其是中考前的总复习几乎是占整个教学时间的一半，要取得满意的复习效果，必须开展有效复习，全面提升复习质量，因此研究复习课的种类及方法十分重要。复习的种类和方法：一、复习的种类：可分为平时复习和阶段复习。（一）平时复习平时复习主要包括引入新课的复习，巩固新课的当堂复习，以及学生课后复习等。1.引入新课的复习新课教学开始，一般要引导学生复习有关的旧知识，这是因为新旧知识之间往往有着密切的联系，旧知识是理解新知识的基础，而新知识往往又是旧知识的扩展、

3、深化、更高的概括或旧知识在新情况下的具体运用。例如在学新课液体压强时，首先复习固体压强的公式、意义和运用，然后再引导到液体压强上来。经常结合新教材复习旧知识，不仅可以强化旧知识，而且可以把新旧知识有机地联系起来，使每节课的新知识置于整个学科体系之中。通过复习，回忆与新教材紧密联系的旧知识，排除其中的疑问，这就为新知识的教学打下良好的基础。同时，在复习旧教材的基础上提出一些有待探索的问题而引入新课，这有助于激发学生的学习兴趣和发展学生的逻辑思维能力。2.巩固新课的复习根据遗忘“先快后慢”的特点，知识的初步巩固应当在头脑里建立新的联系之后立即进行。所以，在讲授新知识的课中，当堂进行复习巩固是十分必

4、要的，它可以起到事半功倍的作用。心理学研究表明：意义识记的效果大大优于机械记忆，因为意义识记是理解为基础的，因此它的效果好，保持持久，且易于回忆。因此，当堂复习巩固，首先要使学生加深理解新的概念、规律和公式的意义，而不是从形式上机械地记忆定义、定律或公式。其次，要把新课内容跟过去学过的有关知识作比较，找出它们的异同，发现它们之间的联系，在知识的对比、联系中，加深理解和记忆，并把新课内容纳入学科知识的总体结构中去。最后，用学到的知识解决实际问题，可以使学到的知识从应用中得到加深和巩固。也可以通过应用来检验学生对知识的掌握程度，比如学生在学过“二力平衡”后，让学生讨论：“起重机将 2000N的物体

12、难点，使学生对概念有了进一步认识。所以，通过当堂分析典型例题或让学生做适当的练习，也可以起到良好的复习巩固作用。平时复习中，有时还采用边学边复习的方式。在学习较难时或层次较多的新知识的教学进程中，对于所涉及的旧知识随时加以复习；或者采取“步步为营”的方式，在新课进行的各个阶段，分段进行复习巩固。3 课后复习。当前中学物理教学中存在着片面重视解题的倾向，学生课后不去复习和钻研学过的基本知识就去做题，结果基本概念不清，基本规律没有理解，势必造成死套公式、应付作业的现象。为此，老师要教育学生，课后要先复习学过的基本知识，后做习题。课后复习应首先阅读课本，边思考：本课主要认识了那些新的物理现象，学到了

13、什么概念或规律；概念的定义是怎样表述的，它的意义是什么；规律是怎么得出来的，它的内容是什么，应用时需要注意些什么等等。课后做练习作业，它是巩固知识的有效途径之一。为此，教师要精选适量的作业，并教育学生为巩固知识、运用知识而认真独立地完成。但应避免作业过多过重过难。（二）阶段复习在教学中，只有平时复习是不够的，为了把知识系统化，掌握知识文档编码:CV3Y6M9Y9S5 HY6Q4L1A7O6 ZX5S2J4H10H1文档编码:CV3Y6M9Y9S5 HY6Q4L1A7O6 ZX5S2J4H10H1文档编码:CV3Y6M9Y9S5 HY6Q4L1A7O6 ZX5S2J4H10H1文档编码:CV3Y

20、CV3Y6M9Y9S5 HY6Q4L1A7O6 ZX5S2J4H10H1结构，有必要在教材的一个单元、一个阶段的学习之后，系统地复习这些教材，在学期和学年末，往往应对教材进行全面的总结性复习。阶段复习主要包括单元复习、期中复习与期末复习和总复习等。由于阶段复习涉及的内容多、范围广，往往需要用整节课或连续若干节课的时间，这些课就是复习课。由于复习教学的内容是学生学习过的，如果复习时再简单地重复和讲解学过的知识和做过的练习，既不能引起学生的兴趣，又不能深化学生的认识和解决学生学习中存在的问题。所以，在复习课进行之前，教师首先要钻研教材和有关的资料，把前后教材联系起来分析，尽可能清晰地理出教材的线索

21、和内在联系，掌握教材的知识结构；另一方面，要深入了解学生的学习情况，掌握学生存在的问题，分析存在这些问题的原因，以便有针对性地进行复习，帮助学生把教材结构变成自己的认知结构，补足或纠正那些在教学中出现的不足。在进行阶段复习时：（1）突出重点，狠抓关键。阶段复习内容多，范围广，不能平均使用力量，必须突出重点，要向学生明确指出那些是必须掌握的重点知识，那些是关键性问题，在重点和关键的地方要针对学生的模糊概念和模糊认识进行讲解或讨论，使学生准确掌握基本知识，获得深刻印象，要从不同的角度抓住教材的线索和内在联系，尽可能地进行分析和比较使学生能够得到新的收获和体会，有助于学生对知识的理解和记忆。有利于知

38、测量原理、步骤、方法。物理知识最重要是学以致用，任何知识只有通过实际运用才能加深理解和熟练掌握，并得到进一步的发展。引导学生善于运用所学的物理知识去解释物理现象、解决实际问题，尤其是日常生活中的一些实际问题，从而激发学生的学习兴趣，提高复习的效率。运用实验进行复习的方式也是多种多样的。例如：将课本上的演示实验让学生重做，同时提出问题让学生回忆和进一步思考；变换实验部件或条件，讨论实验成败的关键及现象之间的因果联系；采用与课本上不同的方法进行演示实验，边演示、边思考、边提问、边复习；举办实验仪器和装置陈列展览，等等。如在初三复习密度这一章节后，可以做如下实验：在下列器材中，量筒、天平、密度计、盐

39、水、弹簧秤、金属块、细线以及一定量的水从中选取合适器材要求学生设计出多种测定盐水密度的方法，从这个实验中可以培养出学生动手实验能力、发散思维能力、理论联系实际和归纳创新能力。再例如，凸透镜成像实验，大部分学生对像与物的变化关系分析容易混淆，文档编码:CV3Y6M9Y9S5 HY6Q4L1A7O6 ZX5S2J4H10H1文档编码:CV3Y6M9Y9S5 HY6Q4L1A7O6 ZX5S2J4H10H1文档编码:CV3Y6M9Y9S5 HY6Q4L1A7O6 ZX5S2J4H10H1文档编码:CV3Y6M9Y9S5 HY6Q4L1A7O6 ZX5S2J4H10H1文档编码:CV3Y6M9Y9S5

46、物近像远像变大，物远像近像变小”，这样规律，实践证明，这些内容通过实验，比单纯的利用理论讲解复习效果要好得多3，合理运用各种现代教学媒体，构建有效复习课堂。比如讲解凸透镜成像这节内容时，为了让学生正确掌握凸透镜成像规律，运用FLASH 物理教学软件，将凸透镜成像跟物体位置有机地结合起来，学生易学易懂，记忆深刻，突破了教学的难点，提高了课堂复习的效率。同时在开展有效的课堂复习中应注意到：能让学生观察的尽量让学生观察；能让学生思考的尽量让学生思考；能让学生总结的尽量让学生总结；能让学生自学的尽量让学生自学；能让学生动手的尽量让学生动手；在复习过程中，最大的优点是能够节省时间和直观性强，同时也能够调

47、动学生的参与意识和创造性，利用多媒体教学复习还可以将所学知识结构通过图表形式进行综合复习，也可对作图题和实验题目的过程步骤进行剖析。以上几种复习方法我们是分开来谈的，在进行具体教材的复习时，也可以采取其中的一种方法，有时也需要将几种方法配合起来。总之，无论是平时复习还是阶段性复习，都不能离开教学大纲的要求和学生的实际情况，在复习方法上更要力求实效，真正实现复习的目的，提高学生综合运用知识的能力和归纳概括的能力。使学生对所学的学科基本知识和基本技能加以巩固、总结，使之系统化、条理化。通过复习可以弥补和纠正学生认识上的错误与缺陷，使学生对知识的理解更深刻、更全面。文档编码:CV3Y6M9Y9S5
