Abstract

With the deepening of research quality education, the cultivation of the ability to solve the problem of high school students in physical modeling and application model has attracted a high degree of attention in high school physics teacher. But how effective physical model of teaching has become the majority of teachers continue to explore the issues. Research students in the physical model to establish the terms of the status quo, to provide a reference for the formulation and implementation of teaching strategies. Literature base at home and abroad on the condition of the physical model research, this study gradually clarify the physical model concepts and common classification methods, understand the process of establishing a common physical model and method. On this basis, combined with the concept of psychological ability, given the concept of physical modeling capabilities to create a physical model of the thought process is broken down into eight indicators: physical scenario analysis, task analysis, the study determines the object of study mechanical analysis and movement analysis, to highlight the main factors and secondary factors are ignored, the model built in the early evaluation of the model to modify the model validation. On eight indicators were refined and quantified, mainly using the measurement and oral reports on the implementation of a measurement study for high school seniors. A more comprehensive understanding of the students' understanding of the physical model concerned about and usually learn the key aspects of the physical model of consciousness, and assisted questionnaires and individual interviews. Comprehensive analysis of the results of the various studies can draw the following conclusions: (1) student physical modeling method mastered relatively small, the lack of basic thinking processes to create a physical model; (2) in the face of a lack of data and off-the-shelf imitate the model of the physical problem, the analysis of the students' problems often fail to highlight the main factors secondary factors are ignored to miss the essence, and the eventual establishment of a scientific and reasonable physical model; (3) comparison of the physical contexts intuitive description of individual students do good, but there is still a problem most of the students, which also affects their physical model: (4) to grasp the characteristics of the original classic physical model is not accurate enough, especially applicable conditions are not very clear ; (5) students' physical model definition, classification and modeling meaning less well understood, which directly affects the student's ability to establish a correct and reasonable physical model; (6) The student usually not in learning special attention to the physical model of active learning even individual students to study physics modeling capability is useless; (7) can also be seen by studying the obvious positive correlation between students of physical modeling capabilities and their physical examinations.
