日本有句教育谚语:“教室就是出错的地方。”我国著名的科学家钱学森也曾说过:“正确的结果往往都是从大量的错误中得出来的;如果没有这些错误作台阶,就登不上最后正确结果的高峰。”在小学数学教学中,很多时候学生的错误也是一种值得利用的教学资源。因此,教师在小学数学课堂中应该充分利用小学生的错误,将错误转化为资源,从而构建精彩的数学课堂。这样,让学生在错误中汲取经验,并不断地从错误中获得进步。一、巧用学生错误,调动学生学习积极性 There is an education proverb in Japan: “The classroom is the place where something goes wrong.” “Qian Xuesen, a famous scientist in China, once said:” Correct results often come from a great deal of mistakes. If these mistakes are not made, It will not be able to reach the peak of the final correct result. "In primary school mathematics teaching, often the mistake of the students is also a worthy teaching resource. Therefore, teachers in primary school mathematics classroom should take full advantage of the errors of primary students, the error into resources to build a wonderful math class. In this way, students are taught to learn from mistakes and constantly make progress from mistakes. First, clever use of student errors, mobilize students to learn motivation
