Development And Practical Research Of Interactive Micro-lesson In Middle School Physics Teaching

With the development of information technology,the way people communicate with the world has also changed.In the teaching,in addition to the dialogue and exchanges between people,also increased the man-machine dialogue and exchanges between,such as mobile phones and tablets and other mobile information terminals with frequently in people’s life,this also is changing the form of students’ learning,with the rapid development of information technology,make the micro-lesson students become the indispensable resources.However,a series of problems have emerged in the development process of micro-lesson: single knowledge framework,unable to achieve personalized learning;Lack of interaction,lack of feedback,lack of supervision and other problems,how to use the innovation of information technology to improve the problems existing in micro-lessons? It is the research of this thesis:making interactive micro-lessons with the interactive video function of Bilibili software.This thesis consists of five chapters.In addition to the first chapter,which introduces the research background,content,methods,purpose and significance,and the fifth chapter,which summarizes and prospects the research,the middle three chapters are the main contents of this research:First,through literature review,the characteristics of "interactive video" and "micro-lesson " are analyzed,and the concept of "interactive micro-lesson" proposed in this study is defined.Meanwhile,the relevant characteristics and platform of interactive micro-lesson are sorted out,paving the way for subsequent research.Second,combined with the theoretical basis and preliminary work,this thesis constructs the development process of interactive micro class,and applies the developed process to design physics teaching cases for front-line teachers’ reference.Thirdly,the designed case is applied to the actual teaching.According to the practice situation,the practical effect of this model is analyzed in all aspects in combination with teachers and students’ interviews,classroom observation,questionnaire survey,etc.,and the advantages and existing problems of this model are summarized,and optimization strategies and suggestions are put forward.Research shows that interactive micro-lesson can effectively stimulate students’ interest in learning,realize personalized learning methods,provide students with highquality learning resources,and develop students’ Autonomous learning ability.
