相信不少数学教师遭遇过这种现象:学生在回答问题中或演板中或作业中或试卷中,看似不合逻辑甚至感觉明显错误的解法但答案(指最后的结果)却又是正确的!也许教师立即断言:“这种解法是错误的,至于结果正确纯属巧合而已.”然后继续表演着自己早就既定的后续教学内容.今天笔者想说:“老师,先别轻易下结论,请您三思而后言.”本文通过对四个看似错误却是正确的真实案例的剖析,并指出其中蕴涵
I believe many math teachers have encountered such a phenomenon: the students in the answer to the question or board or work or papers, seemingly illogical or even obvious wrong solution but the answer (referring to the final result) is correct Perhaps the teacher immediately asserted: “This solution is wrong, as the result is purely coincidental. ” And then continue to perform their own established follow-up teaching content. Today I want to say: “Teacher, do not easily Come to the conclusion, please think twice: ”This article through the analysis of four seemingly wrong real case is correct and pointed out that the implication
