加速度是学生进入高中后所遇到的第一个在初中没有接触过的概念,是学生进入学习物理“台阶现象”的开始.因此,对加速度概念的认知和建构对高中物理学习具有重要意义.本文通过编制测试试题对学生进行测试,进而对影响加速度概念认知的相关因素进行了分析讨论.1物理概念及前概念概念是反映客观事物本质的思维形式,物理概念是反映物理现象和物理过程的本质属性的思维方式,是物理事实的抽象,它是在大量观察、实验的基础上,运用逻辑思维的方法,把一些事物本质的共同特征集 Acceleration is the first concept that students encounter in junior high school after entering high school and is the beginning of students' learning physics “step phenomenon ” Therefore, the cognition and construction of acceleration concept have Significance.This paper tests the students through the preparation of test questions, and then analyzes the related factors that affect the conceptual understanding of acceleration.1 Physical concepts and preconceptions are the forms of thinking that reflect the essence of objective things, and the physical concepts reflect the physical phenomena And the nature of the physical process of thinking is a physical factual abstraction, it is based on a large number of observations, experiments, the use of logical thinking method, the essence of some things common feature set
