在我们平时教学中,批改学生作业和辅导学生综合练习时,常常发现学生在“归纳”或“应用公式”过程中,有忽视题设隐含的特定条件,忽视公式的特例,忽视定义、定理、公式或已知条件的适用范围等情况,也有丢掉了一些应有的结果,或是增加了不符合题意条件的结论的情况。如果对这些问题不处理好,就会在学生中产生对数学
In our usual teaching, when marking students’ homework and coaching students’ comprehensive exercises, they often find that students have specific conditions that are ignored in the course of “induction” or “applying formulas,” ignoring the special cases of formulas, ignoring definitions, theorems. , Formulas, or the scope of application of known conditions, etc., have also lost some of the results they deserve, or have added findings that do not meet the conditions of the questions. If you do not deal with these problems well, you will have mathematics in the students.
