Strategy Research On Solving The Problem Of Movement And Force With Physical Model In Senior High School

When students enter the high school,there is a large "transition" in the learning content and the task.High school physics is significantly different from the junior middle school,not only in the scope of exponential knowledge expansion,but also in depth,which requires learners to pay more attention to the use of abstract thinking.Physics is also a subject that is difficult for high school students to learn.The traditional physics teaching model,which focuses only on knowledge spreading,is becoming more and more challenging.In recent years,as the model has attracted much more attention in physics teaching of senior high school.A large amount of theoretical research has been conducted by scholars at home and abroad.However,there are not so much research on strategical combination of specific examples and physical models.When referred,only a few examples are offered and few physical models are classified according to the physical knowledge module in high school.Also,few studies have been conducted on how a physical model used in specific module.First of all,based on the consulting of a large number of domestic and foreign literature,this paper induces and organizes the achievements and teaching research of physical models in senior school.This paper also defines the concept of physical models,analyzes and summarizes the characteristics of physical models,classification standard and the meaning of physical models applied in physics teaching research.Secondly,this paper classifies,analyzes and summarizes the senior one kinematic statistic of physical models and the strategy of using physical model to solve the problem of motion and mechanics of senior one is preliminarily worked out.Finally,this paper designs the physical model to solve the kinematics problems involving different physical models and put it into practice;this paper also testifies the effect of the model.By observing the application of the model in the class,this paper shows that two students in different levels can be selected to track the situation of model homework.Self-evaluation,peer evaluation,students evaluation and investigation of students’ application rate and accuracy of the physical model can be seen as the basis for evaluation.Based on the above results,the preliminary strategies and practical results of using physics model to solve the high-level movement and mechanics problems are finally obtained.Finally,the strategy of using physical model to solve the problems of motion and force is finally drawn out:the main factors are set up to establish the physical model strategy,analyze the problem to find out the physical model Strategy,a problem multi-mode problem solving strategy.According to the above strategy,the paper puts forward the teaching suggestions of model application:emphasize the importance of physical model,train students ’ability of finding out physical model,strengthen students’ability of model transfer and simplify complex physical model.
