面向MOOC的学习管理系统框架设计

A Framework Design for MOOC-Oriented Learning Management System

大规模在线开放课程(MOOC)是近年来远程开放教育领域出现的一种新兴在线学习模式。它体现了以学习者为中心的教学理念,改变了传统网络课程内容固定、结构化的特征,使学习者获取知识的途径从简单线性转向复杂化、网络化。学习管理系统是远程开放教育的主要媒介,当前大多数学习管理系统框架主要面向传统网络课程,仅支持学习者对课程知识的单方面访问,对以关联主义学习理论为基础,具有更多交互性的MOOC课程模式支持不够充分,因而有必要对当前学习管理系统框架进行改进。面向MOOC的学习管理系统框架,在已有的LTSA模型基础上增加了交互代理和知识代理两个元件,使学习资源数据库的知识可以随课程的进展不断更新,学习者之间可以构建学习网络,通过不同途径获取知识。

The Massive Open Online Course（MOOC） is a new online learning mode thriving in the field of open and distance education in recent years.It embodies the learner-centered teaching idea,changes the characteristic of fixed and structured content in traditional network curriculum,and shifts knowledge acquisition style from a simply linear one to a more complicated and networked one.The learning management system is the main knowledge transfer media in open and distance education.Most existing learning management system frameworks are for traditional online courses,providing learners with unilateral access to knowledge,which can not fully support the MOOC curriculum mode which is based on connectivism learning theory and is more interactive.Thus,it is necessary to modify the original learning management system framework and adapt it to MOOC.In the adapted model,two components are added to the classic LTSA model,namely,the interaction agent and the knowledge agent.The adaptation ensures the constant knowledge update in the resource database as the course progresses,and enables learners to build learning networks to acquire knowledge through different routes.
