| With the rapid development of education,problems such as education inequality and unfair distribution of educational resources are becoming more and more serious.Only some students from key schools can enjoy sufficient educational resources.Children in remote counties and mountain areas cannot receive complete and sound compulsory education because of problems such as funds,teachers,and classroom scarcity,so they create a big gap.After a lot of market research,it is found that live broadcast is the most effective way to solve the problems of unfair educational resources and high education costs.However,the traditional one-to-one live broadcast cost is high,and one-to-many live broadcast is inefficient,so we create a dual-teacher live platform.The platform is aimed at primary and secondary school students and parents across the country.It is based on the teaching resources of famous teachers from all over the country.It is equipped with famous teachers and special teachers from all over the country to create a synchronized live classroom that is consistent with the progress of the famous schools.At the same time,the corresponding tutors are set up for the local education,monitor and supervise the situation under the class,and arrange corresponding operations,so as to improve teaching efficiency,save education costs,solve the problem of uneven distribution of educational resources,and truly realize the students' face-to-face environment with famous teachers and famous schools.Dual-teacher live platform designed in this paper is a project designed and developed for the problem of uneven distribution of educational resources.In line with China Mobile's broadband and network technology advantages,we will establish and improve the live education supporting program,use the data-driven teaching model,use Internet technology to improve learning efficiency,and maximize the use of learning resources and real-time control of learning.Dual-teacher live platform mainly uses the Java language,built the Nginx streaming media server.The teacher avatar,teacher courseware screen and teacher voice are collected and sent to the server.The storage layer uses MySQL cluster services.On this basis,further module division,I have designed and developed user management module,customer service assistant module,courseware switch module,graffiti module,Online Chat module and screen management module and so on.(1)User management module:Mainly responsible for user registration,login,password recovery,permissions and role management.(2)Customer service assistant module:It is mainly responsible for the smooth dialogue between the user and the customer service assistant,answering the user's question and giving a satisfactory reply.(3)Courseware switch module:It is mainly responsible for converting the live course teacher's PPT and other courseware into H5 form and viewing it in the teaching area.(4)Graffiti module:It is mainly responsible for the realization of functions such as graffiti in the teaching area(note annotation,image drawing).(5)Online chat module:It is mainly responsible for the realization of interactive functions such as the detection of the equipment before the wheat,the setting of the wheat,the control of the hands,and the chat of the wheat.(6)Screen management module:It mainly includes the functions of teacher desktop screen sharing,live recording and live playback.Through the Internet education practice project of dual-teacher live platform,it is integrated into the national "Internet+Education" education informationization 2.0 action plan,promoting education equity,promoting education and teaching reform,promoting students' innovation ability,optimizing education structure,and expanding education open cooperation. |
