“学起源思 ,思起源疑” .数学教学中 ,如果教师有意识地设疑问、立障碍、布迷局、揭矛盾 ,那么 ,就能使学生对数学知识处于“心欲求而未得 ,口欲言而不能”的状态 ,从而引动学生探究 ,达到激发思维的目的 .这一教学策略的本质就是通过创设问题情境来激发学生的学习动机 .所 “Thinking about origins and thinking about the origins of thinking.” In mathematics teaching, if the teacher consciously sets up questions, sets up obstacles, confuses the game, and exposes contradictions, then students will be left with a “mind of desire and lust for mathematics”. The state of being unable to speak can lead students to explore and achieve the purpose of inspiring thinking. The essence of this teaching strategy is to stimulate students’ learning motivation by creating problem situations.
