Application And Practice Of Demonstration Experiment In Middle School Physics Teaching

Physics is a natural science based on the theoretical knowledge and experimental results.Most of the theoretical knowledge in physics experiment is a phenomenon related to the abstraction in out;at the same time,but also get a lot of support for the practice of facts.The experiment is the cornerstone of the basic theory,but also to explain the laws of physical phenomena,it has become a prominent means of physics.Physics demonstration experiment is in the process of physics teaching closely around the teaching goals and contents,mainly to teachers as the leading by way of teaching in classroom teaching to guide students to observe physical experimental phenomena.This teaching method can play to stimulate students interest in learning physics,deepen understanding and memory of the requirements of the master courses,while promoting the students take the initiative to think in order to cultivate the learning ability of the role,the physics demonstration experiment is part of the physics teaching is indispensable.Through careful observation and recording of the experimental phenomenon on the study of physics subjects can play a multiplier effect.With the new curriculum reform of physics education in secondary schools,physics experiments will also become an important part of physics teaching,but also by more and more teachers of all ages and attention.However,under the environment of the examination oriented education,there are many serious problems in middle school physics teaching.First of all,teachers lack important knowledge of physics experiment in the daily teaching process and initiative,and cannot arrange and handle the relationship between teaching practice,sometimes,in order to complete the teaching plan to catch the teaching schedule or do not direct saving demonstration experiment;secondly,because the school is the problem of education funds and can not timely the replacement of new teaching experiment device,the experimental equipment of existing dilapidated or missing,unable to carry out the comprehensive demonstration experiment teaching;finally,although some teachers are willing to carry out the demonstration experiment teaching,but based on various factors,such as inadequate preparation,the experimental method is not correct,step less skilled operation,unreasonable these factors which resulted in the demonstration experiment can not be carried out,not only the experimental effect is poor,but not expected The effect,therefore,waste a lot of time.The existence of these problems not only a serious blow to the teacher in the teaching process of demonstration experiment to carry out the initiative and enthusiasm,but not be able to full performance of the demonstration experiment in Physics Teaching in the Middle School of the real role,to improve the quality of education and teaching level produced great impact.Therefore,I will be "the application and practice of experiment in physics as a research topic.The basis for modern education and teaching idea based,according to the basic requirements of the new curriculum reform in physics education in middle school,through various channels to carefully check the status quo of the research on the physics experiment demonstration teaching in middle school,combined with my own teaching practice of physics demonstration experiment to study the theory,to rigorous scientific attitude summed up related methods in physics demonstration experiments in middle school,especially the multimedia technology into a demonstration experiment teaching,so as to improve the experimental phenomena of vivid.The practical teaching of demonstration experiment design as a case study and in-depth penetration of demonstrating experiment teaching at the same time,through theresults of the study were to assess the effectiveness of using SPSS software,and then draw a conclusion of the research.
