Research On Online And Offline Blended Teaching Practice Of High School Physics

At the beginning of 2020,the sudden outbreak of the new coronavirus epidemic led to the suspension of all kinds of schools.In response to the national ’ suspension of classes and non-stop learning ’ directive,schools adopted the relatively new teaching method of live webcast or live television.As the epidemic was controlled,offline teaching began to gradually resume across the country.However,in recent years,with the recurrence of the epidemic situation,offline teaching should be followed up after the resumption of classes,and with the advent of the ’ Internet + ’ era,the combination of various fields and the Internet is becoming more and more closely.The mixed teaching of online and offline combination in the field of education is the inevitable trend of educational informatization.The simple online teaching that was forced to rush during the epidemic has exposed many problems,and the traditional face-to-face classroom also has drawbacks.In recent years,the epidemic situation has been repeated.How to smoothly switch between home online teaching and offline teaching after the resumption of classes is worth pondering.Therefore,the online and offline hybrid teaching that combines the advantages of online teaching breaking through time and space with the advantages of offline teaching and teacher-student interaction deserves our further study.Based on the practice and thinking of blended teaching in high school physics teaching in recent years,this paper summarizes the design principles of blended teaching and the advantages of blended teaching.This paper gives the teaching design of the chapter of " The Achievements of Universal Gravitational Theory " and the case of implementing the blended teaching process.After that,a questionnaire survey was conducted among teachers and students,and the data analysis of the survey results and students ’ test scores was carried out to verify the feasibility and effectiveness of the blended teaching,find out the problems existing in the blended teaching,and put forward the countermeasures to provide scientific and accurate theoretical basis and practical reference for the application of blended teaching in high school physics classroom.Through this study I found :1.According to the test results and questionnaire survey after the actual case of mixed teaching,it is found that the mixed teaching effect is better than the test results of the traditional face-to-face classroom,the students ’ learning task completion is higher,and the classroom performance is better,indicating that the mixed teaching in the high school physics classroom does improve the teaching efficiency and quality.2.Teachers and students have a high acceptance of the mixed teaching mode.They think that this teaching mode can better combine the advantages of online teaching and offline teaching,and can greatly improve students ’ autonomous learning ability and good learning habits.3.The online teaching resources in the blended teaching mode can help students improve their learning efficiency,help students have a deep understanding of knowledge in the offline classroom,and let the students who have the ability to learn lay a solid foundation for knowledge expansion.In addition,the students ’ excellent homework uploaded online also plays a certain role of incentive demonstration.4.Online and offline mixed teaching task arrangement should be differentiated.When designing teaching,the teaching content based on theoretical concepts can be put on the line and learned by students themselves;practice-based or intuitive teaching content can be placed in the offline classroom,so the arrangement of teaching will be more targeted.
