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”的特殊思路解答问题,这样能简化解题步骤,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 in accordance with the conventional thinking of “preparing and seeking after”. However, sometimes, according to its conventional rules, the subject becomes complicated. In such a situation, the teacher should guide the student in another way. Use the internal connection of the conditions in the topic and use the special thinking of “design without seeking” to answer the questions. This simplifies the problem-solving steps, expands the students’ thinking, stimulates the students’ problem-solving taste, and cultivates the students’ spirit of innovation and research ability. .
