在初中数学中,有一类题目需要按“先设后求”的常规思路来解答,但有时按其常规,反而使题目变得复杂起来,遇到这种情况,教师要引导学生另辟蹊径,利用题目中条件的内在联系,采用“设而不求”特殊思路解答问题,这样既能简化解题步骤,又能拓展学生的思维,激发学生的解题情趣,培养学生的创新精神和研究能力。 In junior high school mathematics, there is a class of questions that need to be answered according to the conventional idea of ​​“setting first and then seeking”, but sometimes it complicates the subject according to its conventions. In such a situation, teachers should guide students to find another way, Using the internal relations of the conditions in the subject, adopting the special ideas of “not seeking”, we can not only simplify the steps of solving problems, but also expand the thinking of students, arouse students ’interest in solving problems and cultivate students’ innovative spirit. Research capacity.
