| Physics is an important subject in high school.In recent years,new curriculum reform is being carried out gradually in the country.The core accomplishment of physical discipline,which was officially issued in the new curriculum standard of 2017,consists of four aspects: "physical concept","scientific thinking","scientific inquiry" and "scientific attitude and responsibility".Physical discipline plays an irreplaceable role in the process of cultivating and developing students’ core qualities and enabling them to gradually form correct values,necessary characters and key abilities.However,after the students enter the high school,the content of physics study increases greatly,and the methods of study also undergo a qualitative change.This makes it difficult for many students to study physics in high school.How to make students master efficient learning methods is the problem that the front-line physics teachers always puzzle out.The physical(brain)development of high school students tends to be complete,and the psychological level is close to that of adults in many aspects.The intelligence level initially completes the transition mainly from the concrete,the iconic,the intuitive perceptual thinking to the abstract rational thinking,but often needs the intuitive perceptual experience to support the active thinking.Physics,in turn,is an abstraction hidden in practice.Many laws of physics abstract the actual research object or physical process into an idealized physical model,and then study the physical quantities involved in the physical model and their mutual relations.Helping students to build physical models plays an important role in cultivating students’ physical concepts and scientific thinking.Based on writer’s teaching experience,this paper summarizes the classification of physical models,characteristics of various physical models and the theory of model teaching based on the systematic research of related physical model teaching literature.In addition,this paper takes students in the physics teaching of middle school as the research objects,and investigates the understanding of physics modeling and the status of modeling ability of high school students through questionnaire.The research shows that the physical modeling ability of ordinary high school students is relatively low;the ability of abstract physical model is weak in actual situation.They’re not good at using models to solve practical problems,not so well as seeing through the nature of phenomena;High level students are better than low level students in modeling etc.Secondly,this paper analyzes the reasons for the weak modeling ability of students: 1.Ability factor: high school students are not good enough in abstract thinking and do not understand the concept of physical model;2.Psychological factor: inadequate understanding of the importance of physical models;3.Education factor: schools and teachers do not pay attention to the cultivation of students’ model thinking ability for a long time.Finally,this paper puts forward several suggestions on cultivating students’ modeling ability and building a complete physical system: 1.Cultivate students’ awareness of building physical models.2.Use multimedia to demonstrate physical models to deepen students’ impression and understanding.3.Cultivate students’ observation ability and abstract thinking ability.4.Summarize the characteristics of each physical model;cultivate students’ summarizing ability and so on.Physical models abstract physical phenomena in reality,and then present them to students with an ideal structure model.By observing and exploring the physical model,students can simplify complex problems,which can make abstract physical problems more intuitive to show,and then enable students to master the law of phenomenon prototype easily.In the study of high school physics,the effective establishment of physical model can guide students to understand the objective world more efficiently and learn physics knowledge.Therefore,teachers must carry out physical modeling more effectively and truly improve the quality of physics teaching. |
