Current Situation And Countermeasures Of High School Chemistry Telecast Teaching

With the rapid development of Internet technology,knowledge digitization technology,mobile communication technology,big data technology and so on,the way of knowledge transmission is changing from the traditional one-way transmission to multi-direction interaction,remote network teaching has become the general trend of teaching.Remote live teaching is a new teaching method that adopts modern communication technology to transfer front-end school classes,including sound,video,text,pictures,animation and video materials to remote schools in a short time.Under the supervision and guidance of remote teachers,remote students can participate in high school classroom teaching activities of live schools in real time and synchronously,learn together with classmates of live schools,and share high-quality educational resources.This measure has a great impact on education in remote areas of central and western China,which is conducive to realizing educational equity.In this paper,the literature research method,questionnaire survey method,interview method and quantitative approach are used to analyze the problems existing in the long-distance live teaching of chemistry in the second High School of Zunyi City,Guizhou Province,with the students of grade two and some chemistry teachers as the research objects,These problems mainly include :(1)the remote live class lacks interaction and two-way communication is very weak;(2)The distance broadcast teaching class capacity is large,high difficulty;(3)The role and status of remote chemistry teachers in the remote live teaching of chemistry is low;(4)The school’s management of remote live teaching is not in place.Through further research,it is found that the reasons for these problems are as follows :(1)the distance broadcast teaching model itself is not perfect;(2)Webcast classes lack interest and interaction,which makes remote students lack the sense of participation;(3)Remote students have poor basic knowledge and poor acceptance ability;(4)The autonomy of the remote students is poor,and the preview and review before class are not in place;(5)Lack of communication between near and far chemistry teachers;(6)Proximal chemistry teachers cannot teach students according to their aptitude;(7)Remote chemistry teachers are not sufficiently active in class.In view of the problems existing in the chemistry class of the live broadcast class,this paper proposes corresponding strategies :(1)to enhance the communication and interaction between teachers and students at the remote end,chemistry teachers at both ends and the school;(2)Increase investment in remote live teaching and do a good job in supervision and management;(3)Do a good job of "promoting the excellent and complementing the poor" and give full play to the role and function of remote teachers.
