| With the development of informatization,the Internet+is well known to the public.Internet is more and more widely used in education.Especially under the epidemic situation,the delayed start of school teaching has been converted to online,and the demand for online teaching software has greatly increased.However,starting from the actual network course teaching,the current network teaching application software cannot be completely designed for the characteristics of college teaching,but can only temporarily adapt to the needs of classroom teaching.At the same time,a teaching process often requires a variety of application software to meet the needs of classroom teaching,the process involved is quite complex and more complex applications must be configured,which greatly increases the cost and complexity of classroom teaching,and also weakens the enthusiasm of students to learn.Therefore,it is urgent to design an online course platform that is easy to use and conforms to the online teaching process of colleges and universities.This paper designs an online course platform based on the teaching process of colleges and universities.The main tasks completed are as follows:1.Through the analysis of the theory and practice of network teaching,the network teaching process is designed to realize the network course platform supported by the teaching links of network teaching in colleges and universities.Referring to the SPOC mode,the teaching process is finally designed,including pre-class preparation,classroom explanation,post-class consolidation,and classroom situation analysis.To realize the network teaching process,and demonstrate it through data quantification.2.Based on WebRTC open source technology and the Kurento multimedia server,the control signaling of the online course platform and the load balancing system of a multimedia server are designed.3.Completed the design and implementation of the online course platform.The role use cases are divided into three types:teacher,student,and system administrator.The communication architecture and overall architecture of the system are designed,and the functional modules of the system are divided,including course management,data management,online modules such as class,video playback,assignment posting and submission,and problem discussion has been designed and implemented for each module.4.The implementation of each part based on the design of the test cases,then the functional tests of each part,then the performance tests of the platform.The final results show that the system has achieved the initial design objectives. |
