Research On Development And Application Of Self-made Teaching AIDS In Physics Electromagnetism Of Senior Middle School

The reform of basic education in our country aims to improve the core accomplishment of students.Physics education plays an important role in enhancing students' scientific literacy and ability.Physics experiment is not only a necessary way of teaching and learning in physics teaching.It is also an important way to promote the reform of physics teaching in middle schools and to practice the idea of new curriculum standard.Experimental teaching aid is an important measure and means in physics experimental teaching.The application of self-made teaching aids in physics teaching in senior high school can not only make up for the deficiency of experimental teaching,but also effectively promote students' understanding of their knowledge.In order to cultivate students' operation skills and creative consciousness and develop students' ability in all aspects,the use of self-made teaching aids can better meet the needs of physics teaching in senior high schools.By consulting relevant literature,this paper combs the current domestic and foreign research on the teaching of home-made physics teaching aids in middle schools.The author finds that many countries pay more attention to home-made teaching aids and low-cost experiments through foreign research.Through domestic research,it is found that there are more general and broad studies on self-made teaching aids,and less systematic research on each specific part of physics.In order to further understand the current situation of the use of home-made physics teaching aids in senior high school and the teaching situation of electromagnetics part,through investigation and research,we know that the experimental equipment 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 have little understanding of the meaning of homemade teaching aids.On the basis of investigation,some teachers are interviewed in depth.Through the interviews,it is found that some first-line teachers are powerless about self-made teaching aids,and have their own original ideas and opinions,but give up making because of the lack of methods and experience of making.On the basis of investigation and research,combined with the author's teaching aid development experience,theteaching aid guidance teacher's idea and the experience exchange with the first line teachers,this paper further summarizes the principles,methods and flow chart of the development and manufacture of some self-made teaching aids in senior high school physics electromagnetism.On this basis,the author made a case study on the making and use of electromagnetic teaching aids under the guidance of teacher Wang Defa,such as the demonstration instrument for exploring the magnitude of magnetic induction intensity and the demonstration instrument for exploring the conditions for the generation of inductive current.The background,mode,application in physics class and characteristics of teaching aids are described.I selected two classes in a high school in Yantai.In one class,I applied self-made teaching aids to teaching,and used traditional teaching mode to teach in control class.By comparing the in-class test,academic achievement,classroom performance and communication and feedback with the students in the experimental class and the control class after a semester of practical application,it is found that the incorporation of self-made teaching aids in physics teaching can improve the students' learning effect.Students' interest and attitude in physics learning have achieved remarkable results.It is hoped that through the research of this subject,it can provide some references for the development and use of homemade teaching aids in physics teaching for the majority of senior high school physics teachers,and can make homemade teaching aids play their greatest value in physics teaching in senior high schools.Improve the effectiveness of physics teaching in senior high school.
