【摘要】 在网络化的学习环境中,由于存在着学习需求多样化和缺乏针对性学习内容情况,因此如何提供一套完整的学习模型和学习控制机制对于提高学生学习效率显得尤为重要。基于知识空间理论和高级Petri网技术,建立了基于同一学习内容的,适应不同学习需求和不同学习对象的多层次的学习模型和学习控制机制,通过该模型可以很大程度上满足以上要求,避免了"知识迷路"和"学习迷航",提供更加个性化的学习指导。更多还原

【Abstract】 One of the key issues to improve student learning efficiency is to find the integrated learning model and learning control mechanisms,since there are diverse learning needs and lack of learning content in the network environment.The hierarchy learning model of three layers was put forward based on the knowledge space theory and advanced Petri net.The model can get adapted to different learning requirements for different learners with different levels using the same learning content.To a large extent,the model can meet the above needs and avoid the problems of "knowledge lost" and "learning lost".Thus the personalized instruction for learners can be achieved.更多还原
