Case Analysis Of Pre-concept Diagnosis And Transformation Of High School Physics

Pre-concept is a very important element in the field of middle school education,and it is also a problem that middle school education must face and solve."Physical concept" is the foundation of the core accomplishment of physics discipline,and it is the sublimation of physical concepts and laws in thinking.Understanding the preconcept of physics of middle school students can make the teaching of physical concepts have a target,which is conducive to the cultivation of core accomplishment.Physics concept is a basic and important part of physics knowledge.Students' learning of physics concept is the foundation and key of physics learning.The grasp and understanding of concepts will directly affect students' learning of other physics knowledge.In the traditional physics concept teaching,teachers always treat the students' mind as a "whiteboard" consciously or unconsciously,and instill physics concepts into the students through cramming teaching method,but ignore the students' active construction of learning process,and also ignore the students' own pre-concept.The author consults the relevant theories of pre-concept,studies the literature at home and abroad,and introduces what is pre-concept,the characteristics,causes,functions and influences of pre-concept.Exists in our country to some former hinder physical science concepts in the mind to build,accepting,understanding,diagnosis test system based on mechanics and electromagnetism concept test and domestic mechanics,electromagnetism examination key design about concept questionnaire before high school mechanics,electromagnetism,four middle school in Shanghai as samples,adopts the combination of questionnaire and interview survey before the concept of mechanics,electromagnetism situation of middle school students.Using the method of statistics to analyze the data,the correlation analysis between the former concept and gender,and the correlation analysis between the former concept and student foundation were carried out.It is concluded that the preconcept is universal and has no significant correlation with gender and student basic level.Based on the relevant pedagogy theory and the guiding ideology of the new curriculum standard,the paper summarizes some strategies and methods to transform the former wrong concepts of high school students.A combination of various effective strategies is adopted to stimulate the contradiction between students' old and new thinking,so that students will have cognitive conflict,so as to change or correctly apply the pre-concept,and finally construct new knowledge to form scientific concept.According to the wrong pre-concept diagnosed by the questionnaire survey and the preconcept transformation strategy put forward,a case of targeted instructional design was developed.For the pre-concept,a lot of related research achievements have been made at home and abroad,and the pre-concept transformation theory is becoming mature.Due to the difference of time background,living environment and so on,students acquire different pre-concept through different ways and channels.The samples of this preconceptual diagnostic survey are selected from several middle schools in Shanghai,which,although not representative,are of reference significance to students in Shanghai.It is hoped that this research can provide some references for teachers in Shanghai.
