数学概念是数学知识的灵魂与心脏,是思维活动的核心与基础。人教社章建跃先生对目前概念教学中普遍存在“一个定义,三项注意”的现象,提出必须十分重视概念教学,尤其是核心概念的教学。笔者认为,学生习得数学概念的过程,都需要一个恰适的“问题”为载体,通过设置问题链条让学生在思维参与中体验,使概念在问题驱动下形成。下面试以一则案例谈谈数学概念教学的实践与体会。
The concept of mathematics is the soul and heart of mathematical knowledge, which is the core and foundation of thinking activity. Mr. Zhang Jianyue, a member of the Poverty Alleviation Commission, points out the common phenomenon of “one definition and three notes” in the current concept teaching. He pointed out that we must attach great importance to the teaching of concept teaching, especially the core concepts. The author believes that the process of students' acquisition of mathematical concepts requires an appropriate “problem ” as a carrier, by setting the problem chain for students to experience in the thinking of participation, the concept of the problem-driven formation. Below to try a case to talk about the concept of mathematics teaching practice and experience.
