| Under the theoretical guidance of psychology, ecology and physics,and with foreign and domestic related theory as the foundation, We summed up the source materials of junior high school the original physical problems, teasing out the method of junior middle school original physical preparation, Working out the compiling principle of original physical problems, And based on original compiled the junior high school physics problem scale is used for empirical research. Through data processing and analysis, proving that the measuring tool not only has good reliability and validity, and can comprehensively reflect the students’ ability to solve the problem of physical。Finally, according to the result of research putting forward the corresponding teaching Suggestions. In this paper, the main content is divided into five parts:The first part, introducing the background of the original physical problems. Theoretical research which in both inland and abroad showed that, to develop successfully the creative talents who can cope with the challenge of new century, is bound to break the worse situation of physical exercises teaching unify the whole country。By introducing the original physical problems into the teaching and examination evaluation, to improve students’ability to Satisfied with the demands of the rapid development of society。The second part, introduced mainly involves the relevant theoretical basis in this paper, including ecology theory, this part focuses on relationship between the phenomenon of physics and physics, and the comparison of the original problem and problem sets。At the same time, on the basis of the theory according to the situation of junior middle school students, to formulate the original physical problems based on source of measurement tools, To compile methods and principles.Through the analysis of the pros and cons of SOLO and PTA evaluation standard, we put forward "to make subjective test question, must make the evaluation standard of subjective questions objective", and based on the self-organization theory of characterization, the corresponding source for students to solve problems of characterization phase for the primitive physical problems measuring tool to formulate the appropriate criteria. The fourth part is the practical research part of this study. Using the previously proposed criteria, to quantify the paper processing。 Test data appears to be intuitive in tables and charts and so on, Through the analysis of the data further again, Junior high school, the original physical problems scale reliability, difficulty, degree of differentiation and structure validity indexoThe fifth part, research conclusions were reviewed in this paper, the work done, putting forward the corresponding suggestions to the current physics teaching, Finally in the deep the inadequacies of the research of ruminant, raising the issues worthy of further discussion. |
