物理错题反思方法作者:刘怀敏来源:《新课程·中旬》2016年第03期赵凯华先生曾说过:“学习物理,不做习题是不行的。
但做习题不在于多,而在于精。
习题做完了,不要对一下答案或交给老师批改就完事。
自己应该想一想,答案的数量级是否对头?所反映的物理过程是否合理?能否从别的角度判断自己的答案是否正确?”学生在高中学习物理时当然要做题,但是不能为了做题而做题,正如上文所说的“对一下答案”就完事了。
题目做完后还要进一步思考总结自己的得失,特别是对于做错的题目更需要好好反思。
那么对于做错了的题目应怎样处理呢?对于错题并不能简单地改正,它里面隐藏着大量的有用信息,值得大家好好反思。
反思可以从以下几个方面入手。
一、题意理解的反思题意理解的反思可以从两方面进行:准确度和理解度。
准确度指的是对题目的准确把握。
题目做完,对完答案后应反思自己对题目的条件是不是准确把握到位了。
常有学生考试或是练习中看多或是漏看了题目的条件。
出现这类问题的原因很可能是习惯,即审题习惯马虎大意。
有的学生做题时只是追求数量,总是想着多做几题,审题时一目十行。
此时教师应要求学生沉下心来,认真把每一道题看好、做好。
切不可只是盲目地追求解题的数量,应关注训练的质量和效果。
高三时,有部分学生由于做过一定的练习,形成思维定式,碰到较为熟悉的情景就误以为和做过的练习完全相同,套用已有结论。
此时应指导学生克服思维定式,特别是要注意题目中的蛛丝马迹。
也有可能有的学生平时做练习时情况效果良好,而到了考试时就老是看错题目,比如水平看成竖直,粗糙看成光滑。
越想着要小心越是出错。
还有是应试心理的问题,这类问题应该加强平时的应试心态的调整,比如把平时的练习当成考试来处理。
端正对考试的态度,把每次考试当成一次对自己的检测,适当降低考试的期望值,做到对考试适当的“脱敏”。
理解度指的是对题目所描述的物理情景再现的完整和深入程度。
高考物理注重将基本概念、规律与科学研究进展、生产实践、生活实际紧密联系起来,试题通过对实际问题的合理简化,建立中学物理知识所能解决的模型,考查学生运用物理知识解决实际问题的能力。
