Investigation And Research On The Application Of Physical Model Of Ssenior Three Students

Scientific thinking,as one of the four key themes of physics discipline core literacy,includes model construction,scientific reasoning,scientific argumentation,questioning innovation.Physical model plays an important role in the process of solving students' physical problems.The solution of physics problem is usually the main content for senior three students to review physics.The rational application of physics model to solve problems is helpful for students to consolidate and transfer physics knowledge and promote the improvement of students' core literacy level in physics.On the basis of combing the existing research,this study analyzes the inevitable requirements in the physics teaching of senior three,and completes the questionnaire survey and teacher interview survey of senior three students through the design of investigation tools.The “present” situation of the application of physical model of senior three students is obtained.The questionnaire of the current situation of physical model application in physics review in senior three is constructed and designed from four dimensions: Physical Review,physical model identification,physical model cognition,and physical model application consciousness.After the preliminary survey questionnaire was revised and perfected,a formal questionnaire was formed and implemented the investigation.The results show that the consistency coefficient of the questionnaire is 0.947,the Kaiser-Meyer-Olkin Measure of Sampling Adequacy(KMO)is 0.942.The questionnaire has good reliability and validity,which can better reflect the current situation of application and existing problems of the physical models in the physics review of the third year of high school.The results found that the senior three students did not have enough understanding of the basic physical model,and lack of the consciousness of constructing physical model;The scientific thinking of physical models in teaching is easy to be ignored;and there are difficulties in the application of students' physical model transfer.Moreover,there are certain differences between students applying physical model in gender and school,and there is a positive correlation between student physical learning satisfaction and students can apply physical model to solve physical problems.According to the problems existing in the application of physical model in the review of physics in senior three,the countermeasures put forward in this study are as follows:(1)guiding senior three students to sum up the physics model involved in senior high school;(2)guiding students to construct physical model independently;(3)cultivating students' scientific thinking of solving problems by applying typical physical model;(4)making physical model situational in physics model teaching.According to the above strategies,this study has carried out "inclined plane model"," locomotive start problem"," law of gravity and its application" and other content of physics teaching design cases of senior three,respectively from different angles to guide students to use physical model to solve problems,can be used for teachers in the three review process reference practice.
