| Physics is an experiment-based discipline,mainly including physical theory knowledge and physical experiments.The physics demonstration experiment is an important link for teachers to conduct physics teaching,and it is also an important way and means for students to acquire physics knowledge.It also plays an important role in cultivating students' innovative practical ability and improving students' core literacy.The new curriculum standards fully condensed the core qualities of the physics discipline,further affirmed the role of physics experiments in teaching,sublimated the three-dimensional goals,and paid more attention to the embodiment of the "process and method" goal.Combined with the conversion ideas in the physics learning process,it can help students simplify complex experiments and help students understand and perceive physical phenomena more easily.This article is based on previous studies,combined with relevant literature,guided by the new curriculum reform,constructivist learning theory and Marxist theory on the comprehensive development of human beings,with the goal of improving the demonstration skills of physics teachers and combining interviews with excellent physics teachers.It is recommended that the survey understand that carrying out physics demonstration experiments in the classroom will improve students' learning enthusiasm,activate the physics classroom atmosphere,increase teachers' personal charm,and cultivate students' innovative thinking and abilities.However,on the campus,there are still some shortcomings in the effect of the physical demonstration experiment,such as low efficiency and low student motivation.Therefore,it is of great practical significance to pay attention to the research on the optimization strategy of physics demonstration experiment teaching.In this article,the author combined own teaching practice with interviews and questionnaires to investigate and study the teaching situation and learning situation of physics demonstration experiment in middle school,and analyzed the reasons for the phenomenon of valuing theory over experiment from the perspectives of school,teachers and students,and proposed and summarized some teaching strategies of physics demonstration experiment:(1)introduce new courses efficiently with physics demonstration experiment,(2)design the exploratory experiment to improve the students' ability,(3)standardize the demonstration experiment process to improve the experiment efficiency,(4)the teacher coordinated hisspeech in doing the experiment.On this basis,this article puts forward strategies and suggestions for innovative demonstration experiment teaching in combination with physics experiments:(1)add a large of interesting and inspiring experiments,(2)rational use of multimedia teaching,(3)cultivate students' independent experiment ability,(4)increase low-cost innovative physical experiments,(5)increase visual physics experiments,(6)encourage students to summarize and reflect on experimental operations,and cultivate innovation consciousness.School optimization strategy:(1)pay attention to the development and implementation of primary science,(2)when conditions permit,strengthen the training of teachers' experimental ability,(3)open laboratory and regularly hold experimental exhibition activities.Finally,the research work is reviewed and prospected to provide reference for the development of physics demonstration teaching in the future. |
