学校心理学指出:教学上教师帮助学生形成知识系统,以便加深对已学过概念和原理的理解,并有助于理解掌握新学的概念和原理.(1)在物理课堂教学中,一般应经历“打结·建链·入网”等几个教学环节,才能形成物理知识结构网络.所谓“打结”,指对与以前学过的知识没有联系、具有知识生长点的知识点的学习;“建链”则是对知识点的深化理解,形成知识链;“入网”是将相关知识联系起来,成为知识结构网络.下面以“法拉第电磁感应定律”教学为例,谈谈我们的具体做法.
School psychology points out that teaching teachers help students form a knowledge system in order to deepen their understanding of the concepts and principles that have been learned and to help understand the concepts and principles of new learning. (1) In physics classroom teaching, The “knotting, building the chain, and accessing the Internet” and other teaching steps can form a network of physical knowledge structures. The so-called “knotting” refers to the learning of knowledge points that have no connection with knowledge that has been learned before and that have knowledge growth points; “Building a chain” is a deepening understanding of knowledge points and forming a knowledge chain. “Networking” is to link relevant knowledge and become a knowledge structure network. The following takes the teaching of “Faraday’s Law of Electromagnetic Induction” as an example to talk about our specific practices. .
