数学概念的正确建立,对掌握基础知识、提高运算能力和解题技巧很有帮助。这就要求教师要重视概念教学,关注概念形成的每一个步骤,让学生经历概念形成的过程,帮助学生形成良好的概念网络。然而,由于许多教师常以解题训练为重点,忽视了概念理解的深刻性对解题效率的直接影响,导致学生产生了一个又一个学习障碍。本文结合教学实例,以概念教学的“原点”“节点”“漏点”“接点”为切入口,结合概念学习的“引入”“建立”“巩固”“发展”四个环节,开展对数学概念教学的研究,切实促进知识间的融合互通,使学生深刻理解知识本质,学懂、学透概念。
The correct establishment of mathematical concepts, to master the basics, improve computing power and problem solving skills helpful. This requires that teachers should pay attention to the concept of teaching, attention to each step of the concept of formation, so that students experience the concept of the formation process to help students form a good conceptual network. However, since many teachers often focus on solving problem-solving exercises, they neglect the direct influence of the profoundness of concept understanding on the problem-solving efficiency, which leads to one after another students’ learning disabilities. Based on the teaching example, taking the teaching of “origin” “” “” Consolidate “” development "four links, to carry out the concept of mathematics teaching research, and effectively promote the integration of knowledge exchange, so that students a profound understanding of the nature of knowledge, learn, learn concepts.
