Research On The Construction Of Physics Experiment Images For High School Students

At present,the requirements of social development for physical experiments are increasing.However,in the teaching of physics in high schools,the status of physics experiments is generally low.For the image method of data processing,most students do not know the data processing principles behind these steps.This teaching status is disconnected from the actual subject requirements and social development requirements.Therefore,it is imperative to investigate the degree of understanding and application of image method by high school students in the context of physical experiments,put forward feasible teaching suggestions,and improve students’ ability to process data and construct images in physics experiments.In this study,we preliminarily construct an image evaluation system suitable for high school students.Taking the physics students selected by three classes of a high school in Shanghai as the research object,sixty-six questionnaires were collected and some students were interviewed.The students’ ability to apply image methods in physics experiments was evaluated from seven dimensions.The confusion and misunderstandings existing in the process of constructing images were summarized,and the three aspects of knowledge and skills,teaching and psychology were summarized.Corresponding teaching suggestions were given.The conclusions of this study are as follows: First,the questionnaire and evaluation criteria for high school students’ ability to construct physical experiment images are effective.Second,students’ ability to build models and connect with theory needs to be improved.Third,most senior two students have a relatively good grasp of voltammetry,while the mastery of volt-resistance method and ampere-resistance method is relatively weak,mainly because of the high consistency of knowledge,less teaching reinforcement and the fact that students are mostly at the single point structure and multi-point structure levels in SOLO classification theory.Based on the current research conclusions,this paper puts forward some suggestions on the teaching of physics image method in senior high school: First,we should pay attention to the coherence and subject integration of image method teaching.Second,we should improve students’ participation in the experiment.Third,we should emphasize the cultivation of students’ ability to solve practical problems.
