Case Study On The Development And Application Of Self-Made Teaching Aids In Middle School Physics

In the aspect of basic education,our country pays more and more attention to training students' core discipline literacy and promoting students' all-round and lifelong development.Through the demonstration experiment of teachers and students' hands-on experiment,the teaching contents in the classroom can be made lively,the interest of students in physics learning can be aroused,the students' practical ability can be improved,the spirit of exploration and innovation of students can be cultivated,and the students' all-round development can be promoted.According to the standard of physics curriculum for senior high school(2017 edition,revised in 2020),the physics curriculum for senior high school should help students to understand and understand nature from the perspective of physics on the basis of physics curriculum for compulsory education,and construct relevant physical scenarios.In physics learning,we should pay attention to guiding students to carry out scientific inquiry and experience the process and relevant methods of scientific inquiry,Cultivate students' scientific thinking and enhance their innovative consciousness and practical ability.Using self-made teaching aid in middle school physics teaching is just in line with the recommendations of compulsory education physics curriculum standards and high school physics curriculum standards.It can also solve the problem that the conventional experimental instruments in school laboratory can not promote students' interest in learning.By combing the literature about the research results of self-made teaching aid at home and abroad,it is found that the domestic research on the application of self-made teaching aid in middle school physics teaching is increasing,but most of them discuss the role of self-made teaching aid in physics teaching,covering a wide range,few of them focus on a certain part of the specific content,and most of them are only in theory,There is no specific experimental data support.In many developed countries and regions,self-made teaching aid are paid more attention,and many physics teachers have been committed to the development and application of self-made teaching aid.In order to understand the current use of self-made teaching aid in middle school physics teaching,this study takes the electromagnetics part of high school physics as an example to conduct a questionnaire survey on students,and interviews with front-line high school physics teachers.Through the survey and interviews,it is found that many high school physics teachers almost do not use self-made teaching aid for teaching,Even the basic experimental teaching is mostly replaced by the theoretical explanation on the blackboard.On the basis of investigation and analysis,according to the collation of literature and the author's previous experience of self-made teaching aid,the principle,method and process of self-made teaching aid are summarized,and "electrostatic shielding bag","wind power generator","liquid Lorentz force demonstrator","Electromagnetic induction demonstrator","ampere molecular current hypothesis verifier" are made "Electromagnetic damping demonstrator" and other high school physics electromagnetics related teaching aid.Based on the relevant theories of pedagogy and psychology,this study selected two classes in the practice school to study the role of self-made teaching aid in middle school physics teaching,one as the experimental class and the other as the control class.With the help of the original teacher,the experimental class was taught with self-made teaching aid for one semester,and the control class was taught according to the conventional teaching mode,Before the experiment,the results of the two classes were tested by independent sample t test,and there was no significant difference between the two classes.After a semester of teaching,this study selects three classes to carry out a summary test.Through the students' performance and test results,it is found that there is significant difference between the experimental class and the control class,and then shows that the self-made teaching aid have a significant effect in physical teaching.Hope that the research of this topic can provide reference for the physics teachers in the first-line middle school,and promote the better development of middle school physics teaching.
