Design and research of online education course resource sharing based on cloud platform

设计基于云平台的在线教育课程资源共享平台,平台由云基础设施层、云系统服务层、云应用层和云客户端层组成。其中,云系统服务层内业务管理系统实现平台的业务逻辑。平台依照使用者的权限差异将使用者功能划分成教师与学生两个功能模块:教师功能模块可管理学生、团队、课程、直播等内容,编辑、生成与审批试卷,完成创建、布置、统计学生作业以及上传教学资源等内容;利用学生功能模块可实现教学资源下载、在线作业、在线考试以及讨论交流等功能。平台性能验证结果显示,所设计平台共享资源数量多、内容全面,共享服务效果与平台应用性能得分率均高于0.75,说明该平台对增强教学效果有较大帮助,能够有效增强教育公平性。

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.
