| Physics is a natural subject characteristic of experimental teaching.Demonstration experiment teaching can play a very important role in daily teaching,and it is highly valued all over the world.As an old revolutionary area,Yan ’an has made great achievements in physics demonstration experiment teaching in junior middle schools,but there are still many problems.The most obvious one is that the level of educational development is unbalanced.As a newly developed area in recent years,Yan ’an New District’s educational development level has advanced by leaps and bounds,the application of demonstration experiments in physics teaching is considerable,and it has achieved very good results.On the other hand,due to various reasons,the demonstration experiment teaching in Yan ’an Old Town is not satisfactory.Based on the above background,this paper mainly studies the physics demonstration experiment teaching in junior middle schools in the old urban area of Yan’an:First of all,collect and read the relevant research literature at home and abroad carefully,summarize the research achievements,identify the weak links,and provide accurate reference and enlightenment for the development of this paper.Then,the concepts of experiment,demonstration experiment and student experiment are defined,and the basic theory of this paper is established.Secondly,by means of questionnaire,structured interview and other methods,the present situation of physics demonstration experiment teaching in junior middle schools was investigated comprehensively and deeply from the perspectives of teachers and students,then the collected data were scientifically sorted out and analyzed,try to clarify the present situation of physics demonstration experiment teaching.Thirdly,in order to further see the essence through the phenomenon,this paper makes an in-depth analysis of the present situation of demonstration experiment teaching,and finds out the hidden problems and the causes of the problems.According to the present situation,existing problems and reasons of physics demonstration experiment teaching,the author thinks that if we want to reverse the bad situation as soon as possible,we must improve it from three aspects: schools,teachers and students,and put forward optimization strategies and two case analysis.Finally,the research gives a brief summarize and expectation on future work. |
