广义的前概念是指学生在正式学习或接受某个具体的科学概念以前,头脑中就已经形成的与此概念相关的知识和理解,前概念并非完全正确或错误,因而对物理学科的学习可能有积极的作用,也可能有消极的作用.大概念高度关注知识的生活价值,最终目的是让学生通过知识的迁移解决真实情境中的问题,形成专家思维.笔者基于大概念教学与前概念的研究背景,探究利用大概念教学激活或转化学生的前概念的有效途径.
The generalised pre-concept refers to the knowledge and understanding related to the concept formed in the mind of students before formally learning or accepting a specific scientific concept.The pre-concept is not completely correct or wrong,so it may have a positive or negative effect on the study of physics.The big concept highly focusses on the life value of knowledge.The ultimate goal is to let students solve problems in the real situation through the transfer of knowledge and form expert thinking.Based on the research background of big concept teaching and pre-concepts,this article explores effective ways to use big concept teaching to activate or transform students'pre-concepts.
