袁隆平先生中学时期在学习有理数乘法时对“负负得正”不解,于是问老师．老师告诉他:“你记着就是了．”这个回答使袁隆平认为“数学是不讲道理的”,渐渐地这位未来的“杂交水稻之父”对数学失去了兴趣．袁先生的这一经历值得每一位教育工作者认真反思．学起于思,思源于疑．一个学生能够提出问题,说明他的思维是积极的、主动的,说明他对所提的问题是感兴趣的．然而在实际教学中,教师在处理学生的提问时往往也会犯简单粗暴的毛病,挫伤了学生的积极性．实际上,有时学生的提问是极具创造性的,教师只要真诚地面对,勤奋地付出,就会有意想不到的收获．
Mr. Yuan Longping asked the teacher when he learned rational number multiplication during the middle school period. The teacher told him: “You remember it.” This answer makes Yuan Longping think that “math is unreasonable”, and gradually the future “father of hybrid rice” lost interest in mathematics. Mr. Yuan’s experience deserves serious reflection from every educator. Learning from thinking, thinking from the suspect. A student can ask a question to show that his thinking is positive and active, indicating that he is interested in the questions raised. However, in practical teaching, teachers often make simple and crude problems when dealing with students’ questions, which dampen their enthusiasm. In fact, sometimes students’ questions are highly creative. Teachers need to be honest and face to face and diligently pay, and they will have unexpected gains.
