中学生物理前概念的成因及转化研究

摘要

前概念的普遍存在对中学生的物理学习既有积极的作用又有消极的影响。为把物理前概念转变为科学概念，论文在分析前概念的成因及其特点的基础上，提出了创设物理学习情境，引发认知冲突；因势利导，搭建“脚手架”；建构概念图，强化科学概念等转化策略。%The former concept is common .It has not only the positive effect but also the negative effect on students .To transfer the former concept to the scientific concept ,the passage based on the cau‐ses and characteristics of the former concept ,proposes the creation of physic learning for students ,cogni‐tive conflict ,the strategy of learning students and building the “scaffolding transformation” ,to construct concept maps ,strengthen the conception of science .
