Research On The Development And Application Of Self-made Teaching Aids For High School Physics Electromagnetics

The latest physics curriculum standard clearly states that "on the basis of compulsory education,senior high school physics teaching should further promote the formation and development of students' core physical literacy".From the concept of the new curriculum standard,it can be seen that the basic education in our country pays more and more attention to the improvement of quality education,aiming at systematical improving students' scientific literacy and promoting the development of students' comprehensive ability.Physics education plays an important role in improving the scientific quality and ability of students.Physics experiment is not only an indispensable way of teaching and learning in Physics teaching,but also an important way to promote the reform of middle school physics teaching and Practice the new curriculum concept.Experimental teaching appliance is an important measure and means in Physics experiment teaching.The application of self-made teaching appliance in senior high school physics teaching can not only make up for the lack of experimental teaching,but also effectively improve students' understanding of knowledge,cultivate students' operation skills and innovation awareness,and develop students' ability in an all-round way.Therefore,the use of self-made teaching appliance can better meet the needs of senior high school physics teaching.Through consulting relevant literature,this paper combs the research on the teaching of self-made teaching appliance in senior high school physics at home and abroad.Through the research abroad,I found that many countries attach great importance to self-made teaching appliance and low-cost experiments,and give a lot of reference and inspiration.Through the research at home,I found that there are more general and broad researches on self-made teaching appliance,and each of them is specific to physics There are few systematic researches on the sub-systems.In order to further understand the current situation of the use of self-made teaching appliance in senior high schools physics and the teaching situation of electromagnetics,through investigation and research,it is learned that the configuration of experimental instruments in some schools is aging and short,which can only meet the most basic teaching needs;with the development of multimedia,most teachers prefer to use fast and convenient multimedia to meet the teaching needs;and teachers are self-made teaching appliance There is little understanding of the significance of self-made teaching appliance.On the basis of investigation,in-depth interviews were conducted with some front-line teachers.Through interviews,it was found that some front-line teachers were powerless about self-made teaching appliance,had their own unique ideas and opinions,but gave up making due to the lack of production methods and experience.On the basis of investigation,combined with the author's experience in the development of teaching appliance,the concept of teaching appliance instructor and the experience exchange with the front-line teachers,this paper further summarizes the principles,methods and processes of the development and production of self-made teaching appliance in the Physics electromagnetics part of senior high school.On this basis,I have developed "multi-function ampere force demonstration instrument","lenz's laws demonstration instrument","mutual inductance phenomenon demonstration instrument" and some "interesting electromagnetic demonstration instrument" and other electromagnetic teaching appliance.From the teaching appliance production background,structure and production method,use method and the characteristics of the teaching appliance are described in detail.I choose two classes in a senior middle school in Chongqing.In one class,I use self-made teaching appliance in teaching,and use the traditional teaching mode in the control class.After one semester of practical application,we found that the integration of self-made teaching appliance in physics teaching has significant effect on improving students' learning effect,interest and attitude in physics learning.It is hoped that the research of this subject can provide some references for physics teachers in the development of homemade teaching appliance,and can better play the educational and teaching functions of self-made physics teaching appliance.
