Design And Application Of Micro-video In Senior High School Physics Teaching

Under the advocacy of the "Ten-year Development Plan for Educational Informatization(2011-2020)" and "General senior high School Physics Curriculum Standards of 2017",information technology has gradually been deeply integrated with teaching.Through various teaching methods,using modern information technology to improve students' core literacy has become an important demand for physics teaching.At present,micro-videos have become a Significant resource for classroom teaching due to their short,intensive and interesting characteristics.It can be seen that the foreign research on micro-video started earlier and is currently relatively mature.And the domestic research is later,it is involved in many fields concerning all kinds of subjects.Among them,the research on senior high school physics teaching mainly focuses on the application or production selection of micro-video.However,it has not yet formed a complete research system.So the main research work of this paper is to explore the design,production and application of micro-video for the high school physics(compulsory one)of the Peoples' Education Press edition,on the purpose of providing a reference for the reform of teaching methods in middle schools.This paper is based on constructivist theory,mastery of learning theory,refinement theory,and communicative theory.According to the questionnaire survey,students have a positive attitude towards the introduction of micro-videos,and they prefer micro-videos within 5minutes.Through teacher interviews and analysis of teaching materials,the knowledge points which are suitable for the introduction of micro-video in senior high school physics(compulsory one)are analyzed.“Particles and Reference System” as an example to clarify the basic process of micro video production,there are the following steps to clarify the basic process of micro video production:clarify basic concepts and basic laws,explain course standards,write content briefs and usage suggestions,write micro video script,record audio and make video.Then clarify the learning objectives of the micro video in this section and attach a screenshot and content introduction of the micro video.Writing a design table for each micro-video is designed anddeveloped,which briefly introduces the micro-video content,and writes textbook analysis and suggestions for teachers' application.In order to verify the implementation effect of micro-vision-assisted senior high school physics teaching,this paper constructs the teaching implementation methods based on micro-video before,during and after class,and designs cases for implementation.Through the comparison of students' questionnaire surveys and implementation effects,The results concluded that micro-video can help improve students' scientific inquiry ability and let them interest in physics learning;for teachers,their teaching concepts and teaching methods have also changed relatively.In addition,we found some problems in practice.For example,the number of introductions of micro video,the teachers' role,the motivation of students' enthusiasm and the negative impact of micro video,they all need to be studied and improved in the future.At the end of this article,the corresponding improvement suggestions are also put forward.This paper gives specific guidance on the application of micro video in physics classroom teaching in senior high school.The research results can also provide some references for the design and development of micro video teaching resources in the future.
