Research On Using The Primitive Physics Problems To Improve Students' Ability To Establish Physics Model

With the continuous deepening of the curriculum reform, the original physical problem which focuses on science, technology, and social ties has become more and more important in secondary schools physics teaching . But educates validity is still not entirely satisfying as desired, in which the most prominent aspect is that the students master the book knowledge exactly, but when they experience the original physical problem they can not correctly analyze the physical processes, form the corresponding physical picture, and then build the physical model appropriate to solve physical problems, just simply use the concept in their mind.The primitive physics problems are those physics problems without abstract processing in nature, social life and industry. It comes from the physical phenomenon in objective reality, only the objective and inornate description to the nature or social appearance. The primitive problems also can be called practical problem, which opposed by the abstract problem. Compared to the abstract problem, the primitive problems have the feature of inimitable openness, practicability and exploration, which are more helpful to the emerge of the thinking process. Physical new course require the physical teaching must press close to the real life and actual production, and contact social, science and technology. So, inducing the original problems to the physical teaching could promote the implement of the curriculum innovation more effectively and in favor of the realization of the new curriculum objective.In the resolve process of the primitive physics problems, students must link the physical knowledge to the real physical phenomenon, catch the principal factor, ignore the secondary cause and exclude the irrelevant factor based on the requirement, further construct the ideal object, i. e., abstract the reasonable physical model.Physics model is the support of the whole physics, which play a significant role in the development of the physics. Proper identify, construct and use the model method correctively are the basic quality which should be processed by the students. The primitive problems are the precious resources to cultivate the ability of construct the physics model for the students. Model the primitive problems is an innovative process. The resolve process is just proceed from the reality, proceed from the prototype, reproduce the construct process of the physical model, which cultivate the custom of exercise scientific methods and multiple ideation ability of the students. Introduce the original physical problems to the teaching process accord with the thinking level of the students, which further make the students realize the real meaning, inspire the aspiration to knowledge and learning interest of the students, strengthen the ability of acknowledge, exteriorization and construction, so it play an active function to the students to understand the physical model and model method.Therefore, we propose to carry out the new curriculum teaching idea, start from the origin of physical model and introduce the original physical problems into the physics teaching, giving timely introduction to the students, in order to make the students real realize the construction process and the realistic meaning of the physical model, elevating the modeling ability.Adopt the primitive physics problems to the experimental research of experimental teaching, explore the effect of the primitive physics problems teaching to the conscious and ability of construct the physical model; taken the questionnaire and interview to diagnose the diversity of the meanings of physics model, the meaning of studying the physical knowledge and the difficulties to solve the problem impersonality and truly to the students in these two classes.Select the two keystone classes in one grade of Hebei Normal University attached senior high middle school as the experimental research object, aims to validate the basic hypothesis: Introducing the primitive physics problems into the physics teaching timely could elevate the modeling ability.Through the clinic testing and analyze the statistical data and interview results of the students in these two classes, it certify the basic hypothesis proposed by this study, affirm the feasibility of the experimental program. Some research conclusion can be summarized as: first, introducing the primitive physics problems into the physics teaching timely could preferably advance the development of the modeling ability of the students; second, it can elevate the ability to make a solution of the students; then, introducing the original physical problems into the physics teaching make different teaching effect to the students with different thing ability; last, along with the deeper of the study, taking the original physical problems into the teaching will has a more notable effect.
