The Study Of Junior School Students' Representations In Physics Problem

"From physics to life, from physics to the community" is the basic concept of physics curriculum. One of the ultimate goal of physics education is to improve students'abilities of applying knowledge and solving practical problems, which become the Physics Teaching reform trend.The real situation physical problem, which comes from the real subject of physical environment, the physical phenomena or the physical facts, is different from that of physical exercises. The content is basically visible, tangible, familiar and related with students. It is very helpful for students to apply their knowledge to resolve the practical problems.Representation of the problem is a central part of problem solving, a growing number of researchers on cognitive psychology to solve the problem of discipline problems in the introduction.20 Grade 9 students were selected at random for verbal protocol. Test content is a simple answer problem. Verbal protocol material is in accordance with the basic definition of Larkin to collate. Verbal protocol of the study results show the relationship between native representation and sientific representation and influencing factors of native representation. 200 Grade 9 students were selected at random for group testing. The text group material is in accordance with the basic definition of Larkin to collate. Research shows that junior school students apply knowledge in simple and complex problem representation of the different characteristics. Study further shows the influencing factors of the native representation of the real situation problem. The paper also points out factors affecting external representation as well as the interaction mechanism between the external problem representation and internal problem representation in the junior real situation problem representation.This thesis offers a deeper discussion on the representation of the physical sciences and gives a more detailed supplement for relevant theories. Based on the results, some implications for physics teaching in junior middle school were provided, so that the students'abilities of solving practical problems can be well improved.
