SLeD中QTI服务的实现

Implementing QTI Service in SLeD

当前IMS Learning Design(IMS LD)规范中虽然整合了QTI(Question and Test Interoperability)规范,但是在当前的播放器中却没有很好地整合QTI服务,这就阻碍了播放器和QTI之间的通信,从而不能很好地实现QTI服务。文中针对SLeD体系结构,在该体系结构中加入了中间软件层,利用这个中间软件层实现了播放阶段QTI和播放器的通信。

At present, IMS Learning Design （ IMS LD） Specification integrates QTI （ Question and Test Interoperability） specification, however the integration of the QTI service in the LD Player has not done very well, which hinder the communication between the LD player and the QTI player. This paper aims at implementing communication between the LD player and the QTI player through introducing a middle software layer in the SLeD architecture and system.
