概念是物理基础知识的根基,如定律、原理、公式和定则等都以概念为“细胞”组成,离开了概念,所有的基础知识都成了无源之水,无本之木;如果没有物理概念,就无法形成物理学体系。因此,《义务教育物理课程标准》(2011版)重视概念的教学问题。“课标”指出:“物理概念和规律是课程内容中科学内容的重要部分……应重视学生建立物理概念、学习物理规律的过程。”
Concept is the foundation of the basic knowledge of physics, such as laws, principles, formulas and rules are all concepts of “cells ”, leaving the concept of all the basic knowledge has become a passive water, woodless; Without a physical concept, it is impossible to form a physical system. As a result, Compulsory Education Physics Curriculum Standard (2011 Edition) places emphasis on conceptual teaching. “Class standard ” pointed out: “The concept and law of physics is an important part of the content of science in curriculum content ... Students should attach importance to the establishment of the concept of physics and the study of the laws of physics.” "
