摘　　要：根据不同的学习上下文环境提供合适的学习内容、方式和交互,并在上下文发生变化时进行适应性的调整,是智能教学系统近年来的研究难点之一。为此,提出一种上下文感知驱动的具有适应性的个性化学习及交互方法。首先讨论上下文及其对学习与交互过程的作用和影响机制。然后提出一种以知识图为中心的个性化学习,介绍了学习图的生成算法和操作算子、基于知识图的自适应学习导航及符合用户个性特点和需要的学习序列生成方法。最后对交互行为进行分类,讨论交互行为的实现。原型系统的应用结果验证了所提方法的可行性和有效性,在适应性和个性化学习方面能够较好地满足用户的学习需求。Providing appropriate learning contents , learning style and interaction according to the learning contextu-al environment and adjusting according to its variety are some of the difficulties of the intelligent tutoring system （ ITS） .Hence an approach to adaptive and personalized learning and interaction driven by context-aware computing is proposed.First, the context and its influence on learning and interaction are discussed .Then an approach to per-sonalized learning centering on the knowledge association map is introduced , including the creation algorithm and operators of the map , the adaptive learning navigation algorithm based on the learning map and the appropriate cur -riculum sequencing generation in accordance with the user＆#39;s personality characteristics and needs are described in detail.The interaction behaviors are classified and how to realize the interaction behaviors is discussed .Finally, we implemented the proposal in a prototype of the learning system , and the application results indicate its feasibility and effectiveness .
