物理概念是物理学习的核心,对物理概念的理解正确或是偏差直接影响着学生的物理学习.在正式学习某一物理概念之前,学生往往对相关的物理现象已经有了自己的认识,并形成了一些观点,我们称之为“前概念”.前概念曾一度受到人们的高度关注,正确的前概念对学生的学习有积极的促进作用,能帮助学生更好的理解概念,实现认知结构的同化;而有些物理现象的本质常被物理表象所遮掩,凭直觉认为是正确的前概念却往往是片面或者是 The concept of physics is the core of physics learning. Understanding or correcting the concept of physics directly affects students’ physics learning. Before formal learning of a certain physics concept, students often have their own understanding of relevant physical phenomena and form a Some viewpoints, we call it “preconceptual”. The former concept was once highly concerned by people. The correct former concept has a positive effect on students’ learning and can help students better understand concepts and achieve recognition. Assimilation of the structure of knowledge; and the nature of some physical phenomena is often obscured by physical representations. Intuition is considered to be correct. The former concept is often one-sided or
