based on cloud platform
FAN Ying, LIU Meng
Abstract: An online education course resource sharing platform based on cloud platform is designed. The platform is composed of cloud infrastructure layer, cloud system service layer, cloud application layer and cloud client layer, among which the business management system in the cloud system service layer is adopted to realize the business logic of the platform. The users′ functions in the platform is divided into two function modules: teachers′ function module and students′ function module, according to the different permissions of users. The teachers′ function module can be used to manage students, teams, courses and live broadcasts to edit, generate and approve examination papers, and fulfill the creation, arrangement, statistics of students′ homework and upload teaching resources. The students′ function module can be used to realize the functions of teaching resource download, online homework download, online examination and discussion. The platform performance verified results show that the designed platform has a large number of shared resources, comprehensive contents, and the sharing service effect and the scoring rate of platform application performance are both higher than 0.75, indicating that the platform is of great help to enhance the teaching effect and can effectively enhance the fairness of education.
