A Study On The Physics Life Language Of Junior High School Students Based On The Perspective Of Conceptual Change

Language is the carrier of thinking and expression. Points out by the Theory Of Conceptual Change, the sign of the conceptual change is that students can use their own language to describe and explain the concept exactly, in addition, the students' preconcepts can be reflected by the language of life. From this point of view, the conceptual change is the transition of an expression from life language to language of science. But teachers often ignore this factor, inadvertently form a one?way indoctrination of teaching, which weakens the teaching effectiveness, and the current research about students' life language is still relatively little, especially for physics. So the investigation and study of students' physical life language can contribute to the understanding of students on physical concepts, tracking the process of forming and developing the idea, and help bridge the gap between the life language and scientific language, promote conceptual change, whether in theory or in practice are of great significance.In this study, took "melting" "work" "current" three concepts as examples, surveyed eight grade students in Ji'ning Canal Experimental Middle School by self?designed anonymous questionnaire, then based on the questionnaire results interviewed 8 students. By using the Concept Enumeration Method, the exploration results were analyzed according to the structure of language and the contents of language. The study results are these as follow: in the "melting" concept, the students' original expression of perceptual knowledge are lively and vivid, they are happy to use sentences to express, ignoring object etc. Performance in the "work" concept, the word of "work" is strange to students but with the words of are familiar, "work accumulation in the distance" is strange, characteristics of language content diversity influence the students summary. Performance in the "current", electric limitations on franklinism, familiar with the electrical things, concise classification, good description for characteristics of current appearance etc. In the end, based on the results of the exploration, teaching strategies are given.
