摘要: 云计算技术作为一种新兴的技术,能够提供海量信息的高速处理和安全存储,云计算技术的发展为CSCL系统的建设提供了新的思路。提出了一种面向PAAS模式的CSCL系统。该系统以微软Windows Azure云平台为依托、利用SQL Azure数据库进行数据存储,实现了异质群组、协同工作流等技术,是对云环境下构建CSCL系统的有益探索,此开发模式能减少开发和维护成本。试用表明,该CSCL系统能有效地支持协作学习的开展。

Abstract: As a new technology, cloud computing can achieve mass data speed processing and information security storage. The development of cloud computing provides new ideas and new methods for the CSCL system construction. This paper proposes a PAAS model, oriented CSCL system with low development costs and maintenance costs. The system is built upon Microsoft’s Windows Azure platform, uses the SQL Azure database as the data storage management. A number of technologies adopted in the system, including heterogeneous-group technology, collaborative workflow technology, and so on. It is a useful exploration that CSCL system is constructed with the cloud computing technology. Trial operation shows that system can support collaborative-learning effectively.
