Research of hierarchy online learning model and learning control
多层次网络学习模型与学习控制研究

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.
