Abstract

A computer-based learning system uses knowledge points organized with a predefined multilevel arrangement. Each knowledge point has an information set which may include a knowledge content, an evaluation content and a solution content. For a given knowledge point, the learning system provides the knowledge content and evaluation content, analyzes the user'"'"'s answers to the evaluation content and determines the next knowledge point to be studied by the user based on the user'"'"'s answers and the predefined multilevel arrangement of the knowledge points. The learning system thus provides a different learning course for different users to achieve individualized learning. User'"'"'s learning history may be recorded to facilitate reviews by the user and improve the selection of the next knowledge point. Users may provide feedbacks on knowledge contents and evaluation contents, and may even suggest their own knowledge contents and evaluation contents to improve the learning system and user participation.
