The Research Of The Former Concept(Mechanics) About Physical Of Junior High School

Concept is the foundation of physics, is the guarantee of students’learning, grasp of the concept of physics for students is extremely important. In nanning city in guangxi zhuang autonomous region, a total of 474 four high school students as the research object, the openness of the questionnaire was designed as a survey tool. Research students before there is no system of physics study, about gravity, elastic, friction in physical and mechanical concepts such as former concept. At the same time, analysis the background of the student factors such as gender, academic interest, parents education situation, whether has been to science and technology museum factors on the influence of former concept.The results are as follows:(1) month before the students overall situation of the concept of mistake cognition.(2) the relevant knowledge points clear, but on the interpretation of the physical phenomena is not optimistic.(3) the students before the influence factors of concept formation, gender and the liberal arts branch direction and no obvious difference was found between parents culture influence, and family education before the correct concept has obvious effect on the students.(4) the residence of the city, often live together with their parents, Parents’ cultural degree is higher, and have been to science and technology museum factors obviously influence on before the correct concept.(5) the students’ awareness of gravity concept, friction condition is good, have the right concept before the number of total number of 67% and 33% respectively.(6) the concept of elasticity, the action of force is mutual, the action of force effect, the concept of cognitive situation is bad, have a correct concept of number before respectively accounted for 7%,5% and 0.6% of the total number.Before this study can enrich mechanics study of the theory of the concept, but also for first-line teachers understand a student before concept situation and improve the education idea and teaching design to provide the reference.
