Teaching Experiment Research On Model Construction In High School Physics Exercises

Traditional concept of education holds the view that the primary goal of teaching is to teach students knowledge while rarely involved in learning strategic knowledge. Currently, in High School physical exercise, the established model will be presented directly to students in terms of application of model. In practical teaching, due to lack of the guiding process which can help students build physical model, students hardly have flexibility to build a physical model when they encounter real problems. Hence, "one seemingly understands while does wrongly in real exercise" sounds no weird. Therefore, it's necessary to improve students'ability of analyzing and generalizing important physical model, and the ability of answering applied physical model exercises.Considering that, the author reads a lot of literature at home and abroad, and summarizes the existing research results and the shortage. It has some practical significance to study the model building in physical exercises teaching of high school.Based on the Problem Solving Theory, the Cognitive Learning Theory, and the Construction-ism Theory, this article elaborates the knowledge related on the physical model. In the process of teaching practice, based on the strategical analysis of answering the physical exercises and building model, the author chooses the "part of physical model of force and motion" as the case, During internship, the author selects two parallel classes as the research object. Through testing and interviewing some students, the author finds out the problem existing in the application of physical model among students. According to the current circumstance of students building model, the author makes the appropriate instructional design, explains how the physical model apply to exercise teaching in detail.and makes it to teaching practice.In the course of teaching, the specific designed teaching was carried out on the experimental class, great importance was attached to cultivate students' consciousness of modeling, while the traditional teaching methods was used in comparative class. After about five months'experiment, the author gives the same tests for the two classes, the results show that the students in experimental class doing much better than those in comparative class.The main results of this research as follows:(1) Putting forward the strategies of constructing the model and making the analysis in physical exercises of senior middle school(2)Taking "Elementary Education Curriculum Reform Outline (try out) "and "Ordinary High School Physics Course Standard (experiment)" as the theoretical basis, and clearing up the model of the content of "force and movement" in physics of senior middle school.(3)Concluding that the application of physical model to teaching courses has certain practical significance through a semester of practical teaching and study.(4)Summing up several suggestions when the author combined with experimental study and his own experience, which aiming to help students improve their abilities of building physical model, and providing a reference for teachers.
