Application Of Self-made Teaching Aids In Middle School Physics Teaching

Physics is a subject based on experiment.Experiment plays an irreplaceable role in Physics Teaching in middle school.However,in practical teaching,experimental teaching is often affected by instruments,venues,environment and other factors,so it is difficult to play its due role.Therefore,teachers can design self-made teaching aids to solve these problems and improve the efficiency of experimental teaching.Combined with the theoretical basis of self-made teaching aids,the experience of participating in the competition and the cases of self-made teaching aids,the author understands the application of self-made teaching aids in senior high school physics teaching through questionnaire survey,and finally designs three cases of applying self-made teaching aids to teaching practice.The first chapter is the introduction,which consists of three parts: the first part is the research background and significance,which introduces the new requirements for Physics Teaching under the background of the new curriculum reform,as well as the changes of experimental teaching in the old and new physics curriculum standards for senior high schools,and expounds the research background,purpose and significance.The second part is the research status at home and abroad.By comparing the similarities and differences of research trends and research directions at home and abroad,it is found that there are some problems in domestic research,such as insufficient depth,insufficient comprehensiveness,unbalanced and imperfect development and so on.The third part lists the research methods used in this paper,mainly including literature analysis,questionnaire,software analysis and interview.The second chapter is the production and design cases of self-made teaching aids.Based on constructivist learning theory and Dell's "Tower of experience" theory,this study expounds the principles,requirements,material selection and methods of self-made teaching aids.Combined with the theoretical basis,this paper introduces the design cases of self-made teaching aids and combines theory with practice.The third chapter introduces the application of self-made teaching aids in high school physics teaching at the present stage,analyzes the survey results through teacher interviews and student questionnaires,combined with SPSS,provides data proof for this study,and analyzes the reasons.The fourth chapter is the case study of self-made teaching aids used in physics teaching.It selects "Newton's first law","overweight and weightlessness" and "prevention and application of static electricity" for teaching design,and integrates self-made teaching aids inertial demonstrator,overweight weightlessness demonstrator,electrostatic shielding mobile phone,electrostatic precipitator and electrostatic copier into teaching,so as to provide reference for the integration of self-made teaching aids into classroom teaching.The fifth chapter is the research conclusion and prospect.
