基于云计算的在线课程资源共享平台设计

Design of online course resource sharing platform based on Cloud Computing

针对当前各种网络教育资源共享系统普遍存在的资源内容重复率高、无效资源较多、资源质量差异较大等问题,本文提出并设计了一种基于云技术的共享系统。系统主要包括云客户端层、云应用层、云平台服务层及云基础设施层四个层级。系统用户分为教师和学生两个部分,教师用户可以上传学习资源,对直播、课程、团队、学生进行管理,布置、整理作业,创建、编辑、批改试卷;学生用户可以下载学习资源、在线完成作业、在线答题,还可以互相交流。经过实验验证,本文所设计的网络教育资源共享系统资源丰富、覆盖面广,系统资源共享效果和系统运行性能得分均超过0.75,表明本系统能够有效增强网络教学效果,也有助于提升教育公平性。

In view of the common problems of various network education resource sharing systems,such as high repetition rate of resource content,many invalid resources,and great difference in resource quality,this paper proposes and designs a sharing system based on cloud technology.The system mainly includes four layers:cloud client layer,cloud application layer,cloud platform service layer and cloud infrastructure layer.System users are divided into two parts:teachers and students.Teachers can upload learning resources,manage live broadcast,courses,teams and students,arrange and sort out homework,create,edit and grade test papers.Students can download learning resources,complete homework online,answer questions online,and communicate with each other.Through the experimental verification,the network education resource sharing system designed in this paper is rich in resources and covers a wide range of resources.The score of system resource sharing effect and system operation performance is more than 0.75,which shows that the system can effectively enhance the network teaching effect,and also help to improve the education fairness.
