We propose and implement a novel online learning system, called CogLearn, to support learner's self-awareness and reflective thinking, which urges a proper form of knowledge representation together with individual learner's cognitive status. We thus design and employ the machine learning techniques to estimate learner's cognitive status and identify educational relations to construct the desired knowledge representation, namely cognitive graph in our system. We further demonstrate the system by presenting two practical services, i.e., learning obstacle diagnosis and learning path planning, to demonstrate how the constructed cognitive graph effectively and adaptively supports individual system user's learning process. |
