Before High School Physics Concepts Into Strategy

Physics concepts are a summary and description of the characteristic attributes of physical phenomenons and process, is the fundamental form. They are the basis and important part of physics. The teaching of physics concepts is not only emphasis but also difficult in middle school physics teaching. It is has been realized that the effect of student's wrong ,unsuitable, uncompleted physics preconception on construction, acceptance, comprehension and application of the physics concepts, is one of the reasons that the physics concept is hard to teach and study. The research to middle School physics concepts has become an important subject of physics education research both at home and abroad.This thesis founded on the former achievements and guided by pedagogic, cognition, philosophy and the theory of Structural Curriculum. in reference to the phenomenon's that plenty of preconception in student's minds are disadvent in constructing, accepting and understanding. Combining with my several years' teaching experiences, done a careful research with the middle school physics concept teaching, raised a teaching mode tested in practice that is convenient for teacher to operate, and discussed the advantages of this method in converting physics preconception to scientific physics concept compared with traditional teaching methods.Main researches as followed:1) Through questionnaires and interview, the investigation, analysis of composition and contributing factor were gained.2) Through the statistics of the "physics preconception test" exercises, we proved that physics preconception exist commonly and there are differences between different grades., pointed out that traditional teaching methods hadn't converted physics preconception to scientific physics concept successfully3) Based on former physics concept teaching mode, we suggested before class and in class teaching methods that could converted physics preconception to scientific physics concept by view of "Interactive—Engagement method", and made a teaching test, got some a positive conclusions.
