Research On Teaching Of Mechanics Model Based On Original Problems

Model teaching has always been the focus of physics education.Let students know the meaning of the model,and quickly identify and skillfully use the physical model when encountering problems.It is not only the requirements of the new curriculum standard for teachers,but also the requirements of the college entrance examination for students.The high-level mechanics problem is the foundation and key of high school physics learning.It is the first step for students to learn the physical model.The original physics problem is a new form of physics practice in recent years.Due to its own characteristics,it has greatly promoted students’ modeling ability and problem solving ability.Based on the above background,this thesis explores the role of primitive physics problems in modeling teaching through literature review,questionnaire survey,teaching practice and other methods,observes students’ performance in teaching practice,and summarizes teaching strategies.This thesis is segmented into the five parts: The introduction part introduces the research status of the original physics problem and the physical model teaching at home and abroad,and summarizes the existing thesis,explains the research significance and main content.The second chapter gives the definition of the original physical problem and physical modeling.Several key mechanics models of the first stage are sorted out,and the original physical problems corresponding to them are given.combined with the constructivist theory and knowledge transfer theory in educational psychology,to provide a theoretical basis for teaching practice.The third chapter records the main processes of practice,including research preparation and teaching records.A mode of classwork based on group cooperation was proposed,and a detailed flow chart wasgiven.The fourth chapter compares and analyzes the performance of students before and after practice,and gives the specific teaching strategies to promote students’ modeling ability,and gives solutions to the thinking set.The fifth chapter summarizes the full text,sorts out the main innovations of this paper,and puts forward the prospects for the shortcomings.At present,there is almost no original physics problem to optimize the complete study of the high-level mechanical model teaching.Some of the related articles mostly stay on the validity analysis of the original physics problem for the improvement of students’ modeling ability,and the specific teaching practice and teaching strategies are involved very few.In this paper,a detailed analysis of the mechanics part of the first-stage stage is carried out,which restores the student performance in teaching practice to the greatest extent,fills in some gaps in related research,and provides some immature references for front-line teaching.The defects of this article will also be continuously improved in the future teaching.
