The Practical Research On Improving And Making Teaching Tools For Physical Electrical Demonstration Experiment In Junior High School

The physics is a natural science based on various experiments.In the junior middle school,the teaching tools of the traditional demonstrative experiment are important for the students in the acquisition of basic physical conceptual knowledge,they also play an important role for students in experiencing the process of scientific inquiry,cultivating students' observation and operational ability.In recent years,the new curriculum standards for junior high school physics emphasizes that physics course should be close to the real life,let the students gain the perceptual experience,and enhance their learning interest.Teachers should not only use the teaching tools of traditional demonstration experiment well,but also make further modification for the shortage of the teaching tools of demonstration experiment or make the tools by themselves.Teachers should also be able to play a greater role by improving the existing teaching tools,and can make some simple demonstration teaching tools to make up for the shortage of existing teaching tools.In this article,it discusses about the improvement and manufacture of the electricity demonstration experiment teaching tools for junior high school.First,using literature research method reviews and analyzes the physics experiment teaching tools with some literatures at home and abroad,it also uses the research method and statistical analysis method to make two questionnaires for students and teachers,the data was analyzed by rigorous scientific attitude,gathering the main problems existing in the teaching of physics demonstration experiment,and getting a collection of attitudes and perceptions of teachers and students for the physics demonstration experiment teaching,and then investigating and analyzing the status of junior middle school physics experiment's teaching tools.Secondly,this article introduces the educational theories related to the junior high school physics demonstration experiment's teaching tools,which mainly include humanistic learning theory,situational teaching theory,constructivism theory,and the theory of experience tower.On the basis of it,it further theorizes that the junior high school physics demonstration experimental's teaching tools should follow the improvable and self-made principles,including the main principles of science,interest,economy,effectiveness,interaction,repeatability.Then,combining the improvable and self-made principles of junior middle school physics demonstration experiment's teaching tools,it introduces the specific methods and procedures of junior middle school physics demonstration experiment's teaching tools,and it also enumerates some examples of the improvement and self-made of the teaching tools,combining my teaching experience.Besides,it also gives two application cases of the "phenomena" and "electric road's connection" by selecting two same level classes to do comparative test.Through 5 weeks' study,it shows that the learning enthusiasm and the grade of the experimental class are better than the comparative class,so it has a better teaching effect.In the end,this artical summarizs the improvement and production of physics demonstration experiment teaching tools in junior middle school,and the problems to be further studied are also discussed.
