Research And Practice Of Model Construction In Senior Physics Exercises Teaching

The knowledge structure of physics plays an important role in the selection of majors and the training of scientific thinking for students in university.As a result,the education sector is placing increasing emphasis on students' physical studies in high school.According to the Requirements for Selected Subjects for Majors(Classes)to be Enrolled in Ordinary Colleges and Universities in Beijing in 2020 released in May2018,it can be seen that the number of majors that must be selected for physics has greatly increased.In recent years,as the new reform of college entrance examination is gradually covering all provinces and regions,more and more candidates are about to take the "3+1+2" mode of examination.Physics,as "1" in the "3+1+2" model,is a compulsory subject,which shows the irreplaceable status of physics in high school and the teaching of physics exercise is particularly important.This paper will discuss the application of model construction in the teaching of physics exercise in high school from the following aspects.First of all,the research background and significance of the thesis are described based on the question trend of the new college entrance examination.By consulting a large number of literatures on physical model construction,the research status of model construction at home and abroad in recent years is summarized.In the study of the teaching case of physics exercise teaching in high school,it is found that there is no novelty or uniqueness.Therefore,this paper thinks that it is necessary to study the combination of model construction and exercise teaching.By determining the research direction and consulting a large number of relevant literatures,the relevant theoretical basis is determined,which provides an important theoretical basis for the research on model construction in the physics exercise teaching of high school.Secondly,through interviews with teachers,the current teaching methods and forms of teachers in the exercise teaching are learned.And the questions of the questionnaire are determined by understanding the process of key teachers guiding students to answer the exercises,and summarizing and analyzing the situation of model construction in the physics exercises teaching of high school.In addition,according to the results of the questionnaires filled in by the students,the students' problem-solving situation is analyzed to pave the way for the application of physical model construction in the practice teaching.Finally,taking the exercise class "Application of Newton's Law of Motion" as a teaching case,the teacher classifies and summarizes eight physical models related to Newton's second law,and explained the model construction method and the problem solving process to the students one by one.The students in the same class are tested before and after learning the physical model,by comparing the two scores and problem-solving situations,the influence of model construction on problem-solving ability is analyzed.In conclusion,the paper summarizes the practical value of physical model construction in physics exercise class of high school.In teaching practice,the author deeply realizes that students lack problem-solving ability.For students,however,not only grades are important,but also thinking skills.Therefore,in order to improve students' thinking ability and thus improve their physical performance,this paper introduces the physical model into the exercise teaching.The author preliminarily studies the teaching methods in the exercise teaching,applies the research results to future teaching,and provides some references for front-line teachers to introduce physical models in the exercise teaching.
