摘要
从分析异步协同学习中的交互行为出发,针对社交网络信息过载,内容难以沉淀等问题,提出基于社交网络实现异步协同学习系统的设计.其中包括群体交互方式的设计,协同推荐算法设计,支持概念图的内容模型设计等.
By analyzing the interactive behaviors in the asynchronous collaborative learning, and aiming to prevent the information overload and the difficulty of content precipitation, a asynchronous collaborative learning system based on social network sites was designed. The system contains group interaction, collaborative filtering recommendation algorithm, and content model supporting the concept map.
