Research On The Construction Of Popular Science Micro-videos Library And Teaching Case Design In High School Physics Teaching

With the rapid development of the Internet era and educational informatization,China’s construction and investment in information-based education are also increasing.The Notice on Using science Popularization Resources to promote the work of "double Reduction" points out that high-quality science popularization resources should be actively developed and selected,Therefore,all sectors of society and schools are vigorously developing popular science teaching resources.Due to its various advantages,popular science micro-videos can become a good teaching resource to assist high school physics teaching.However,in today’s era,there are many short video platforms,and the threshold for micro-video production is low,resulting in uneven quality of popular science micro-videos across various network platforms.This phenomenon not only hinders the progress of popular science work,but also affects the efficiency of teacher preparation to a certain extent.In order to solve the current shortage of physics teaching resources,this article conducts research from the following aspects.The first part investigates and analyzes the current situation of the application of physics popular science micro-video in physics teaching,in order to explore the understanding,development,and application of physics popular science micro-video among senior high school physics teachers;In the second part,the acquisition platform of physics popular science micro-videos is sorted out,and high-quality popular science micro-videos are selected and sorted out.The resource library suitable for high school physics teaching is compiled,and the principles for screening popular science micro-videos are summarized;In the third part,I try to integrate TPACK theory into the process of popular science micro-video teaching,design teaching cases for two types of courses: conceptual and regular,and propose corresponding teaching suggestions.The research results show that high school physics teachers have a high degree of recognition for physics science popular micro-videos,which can not only improve teaching effectiveness,but also help improve teachers’ ability to apply modern information technology to teaching.Secondly,the construction of a physics science popularization micro-video resource library has made up for the shortage of information-based teaching resources in high school physics teaching.Finally,the application method of integrating science popularization micro-video into high school physics teaching is illustrated with teaching cases,solving the problem of how high school physics teachers can effectively utilize science popularization micro-video resources.
