基于Web Services的CELTS学习者模型

CELTS Learner Model Based on Web Services

通过分析现有网络教学管理模式在多个异构平台间数据共享方面的不足,基于CELTS规范提出了一个学习者模型,并讨论了在该模型支持下学习者行为数据如何通过Web services技术在异构子系统之间实现交互与集成。最后以一个学习行为评估子系统为例,使用SOAP和XML技术给出了该模型在Web services平台下的一种实现。

From the analysis of disadvantages of traditional Web-based instruction management system in data and information sharing among multiple heterogeneous platforms, based on CELTS standards, this paper proposes a novel learner model in the background of developing national de）, technologies R＆D program “distance learning key technology and model engineering”. And then it discusses the learning behavior data interaction and integration among heterogeneous systems employing Web services technology. In the end, it introduces a learning behavior evaluation solution based on Web services platform including SOAP messaging and XML technology, etc.
