Research On Improvement Of Wave Optics Experiment Teaching In High School Physics

Experimental teaching plays an important role in high school physics teaching.In wave optics teaching,the phenomenal experience is more important than other physics teaching course.So the value of experiments teaching are more prominent than other course.In recent years,many scholars work on the improvement of wave optics experiment teaching,but these works can not fully match with the equipment conditions in the present high school often.In the new version textbook of high school physics.the teaching and experimental contents of wave optics are adjusted.However,the experiment in the textbook can not be implemented because of they use the expensive and frangible devices.Therefore,we need systematic and easy solutions to high school physics wave optics teaching content design and equipment production.Firstly,the current situation of the use of experimental instruments in the teaching of wave optics in high school is investigated and analyzed.At the same time,we refer to the literature on the improvement of wave optics experiment,and learn the experiences in the development and improvement.Secondly,the content of wave optics experiment in the new and old version textbooks is compared,and the reasons for the adjustment are analyzed.Through interviews with senior high school physics teachers,the teachers’ views on the rationality of the experimental content arrangement in the new and old high school physics textbooks and the using of wave optics experimental instruments are understood.Then the problems in the current teaching of wave optics experiment in senior high school physics are analyzed.Finally,by considering of the reasons for the text book content adjustment and the problems in the experimental teaching,some teaching experiments contents are innovated based on using of low equipment cost and low skill requirements.There are seven teaching experimental contents are improved,including double slit interference;thin film interference;single slit diffraction,circular aperture diffraction,disk diffraction,grating diffraction;light polarization.
