在数学教学中,课题引入需要情境,解题教学需要情境,培养学生的思维能力也需要情境。实际上,问题情境创设得好,能够充分调动学生参与课堂教学活动的积极性,使学生进行经历、观察、分析、类比、联想、归纳、抽象、概括、推广等思维活动,从而探索规律,得出新的数学知识,使学生体验到数学知识的产生过程,提高他们对数学的认识水平,掌握数学思想方法,培养数学能力。下面,略谈几点我在课堂教学中创设问题情境的尝试。
In mathematics teaching, the subject needs to be introduced into the situation, problem-solving teaching needs situations, and training students’ thinking ability also needs situation. In fact, the problem situation is well established, which can fully mobilize the enthusiasm of students to participate in classroom teaching activities so as to enable students to think through experiences, observation, analysis, analogy, association, induction, abstraction, generalization and promotion to explore laws The new mathematical knowledge enables students to experience the production of mathematical knowledge, improve their understanding of mathematics, grasp mathematical thinking and methods, and develop mathematical ability. Below, I will briefly talk about some of my attempts to create a problem situation in the classroom teaching.
