我们常把物理学比喻为一座宏伟的大厦,那么物理概念无疑是这座大厦的基础。由于前概念的负作用,导致大多数学生的概念基石并不牢固,常常表现出“错误概念屡教不改”的现象。本文的目的是通过对前概念的形成、特点进行分析,结合教育心理学原理,找到由前概念向科学概念转变的教学策略。 We often compare physics to a magnificent building, so the concept of physics is undoubtedly the foundation of this building. Due to the negative effect of the preconceptions, most of the students have a weak foundation of the concept and often show the phenomenon of “the wrong concept of infuriation”. The purpose of this paper is to find out the teaching strategy of changing from preconception to scientific conception by analyzing the formation and characteristics of preconception and combining educational psychology principle.
