Research On The Improvement Of Demonstration Experiment In The Classes Of High School Physics Concept And Law

Physics demonstration experiment is an important part of physics experiment teaching in Senior High School.It can make students feel wonderful and rich physics experiment class and help students understand abstract and difficult physics concepts and laws.So I choose the improvement of demonstration experiment in High School Physics Concept and Law Class as the research topic.In this thesis,by compiling the questionnaire and educational investigation,the following deficiencies have been found in the demonstration experiment teaching of physics concepts and laws in Yueyanglou District of Yueyang City: Teachers and students do not pay enough attention to the demonstration experiment in senior high school physics concept and law classes.The degree of participation and satisfaction of students in the demonstration experiment are low.Teachers lack of research and innovation consciousness in demonstration experiment teaching.The teaching effect of demonstration experiment is affected by experimental equipment,experimental phenomena and experimental conditions.There is a lack of excellent teaching design of demonstration experiment in senior high school physics concept and law classes.The evaluation system of demonstration experiment teaching effect need to be further improved.On the basis of investigation and literature research,I put forward four strategies to improve the demonstration experiment in physics concept and Law Class in senior high school,which are:(1)creative improving the demonstration experiment so that students can "see" or "hear" or "experience" the existence of the corresponding physical knowledge,and It has been greatly improved students' participation and interest in learning physics for increasing student activities in the instructional design;(2)a series of physics teaching AIDS with simple structure,easy operation,obvious phenomenon,durable and low cost have been made by using the familiar objects in students' life,the physics teaching AIDS can greatly improve the teaching effect in the high school physics concept and the Law Education;(3)increasing the demonstration experiment and inquiry experiment of mechanics part appropriately for helping students master the essence of physical concepts and laws;(4)optimizing the design of demonstration experiments for cultivating students' learning interest and practical innovation ability.(5)in a creative way,proposing to understand Lenz's law by using the laws of energy conversion and conservation,distance inertia and magnetic flux inertia,in the design of the demonstration experiment in the LENZ's law,at the same time,the teaching method of analogy being used to cultivate the students' creative thinking ability.It is hoped that this thesis can provide some useful references for the further improvement of physics teaching in senior high school,and thus promote the active exploration of senior high school physics teachers to improve the demonstration experiment,so as to better play the teaching function of demonstration experiment.
