许多学生在初次接触化学时潜意识中认为化学概念非常难懂、难学,在认知行为上有所排斥和恐惧,教师在对基础化学概念进行教学时也很难形象生动地解释这些化学概念.这些问题的产生就是因为学生潜意识中的迷思概念在作祟,也就是把将生活经验与化学概念混为一谈,并产生与科学概念不一样的理解.本文从首先阐述了迷思概念的定义和特定,研究了其形成原因,并探索了高中化学中转变迷思概念实现有效教学的策略. Many students think that the concept of chemistry is very difficult to understand, hard to learn and repel and fear in cognitive behavior when they first touch on chemistry. It is also difficult for teachers to vividly explain these concepts when teaching basic concepts of chemistry. These problems arise because the concept of myths in students’ subconscious is causing trouble, that is, to confuse life experience with chemical concepts and produce different understandings from scientific concepts.This paper first elaborates the definition and specific, Studied its formation reasons, and explored the strategy of changing myths in high school chemistry to realize effective teaching.
