数学作业是数学教学实践的一个重要内容,但在作业批改时教师往往会发出这样的怨声:“真是气死人了!这些题型我都快讲烂了,学生怎么还是出现这么多错误!”而且在评讲作业时,教师还特别注重学生出错较多的地方重点讲解,但下次出现类似的题型学生仍然“我行我素”。这个问题可能是困扰大多数数学教师的一个难题。如何才能减少或避免这种学生屡犯错误的毛病呢?只能静下心来分析原因、了解实情,才能找到解决问题的根本办法。 Mathematics homework is an important part of math teaching practice. However, when the homework is changed, the teacher often sends out such a grudge: “I’m so mad! These questions I almost talk bad, how are students still so many mistakes! ”And in the assessment of homework, teachers also pay special attention to the students focus more on error-prone areas, but next time a similar type of questions students still . This problem can be a dilemma for most math teachers. How can we reduce or prevent this kind of student from making mistakes again and again? Only when we stop to analyze the reasons and understand the facts can we find the fundamental solution to the problem.
