An adaptive activity sequencing instrument to enhance e-learning: an integrated application of overlay user model and mathematical programming on the Web

Learning through hypermedia has become common in both formal and informal education and it started emerging by great influence of web technologies. Adaptive educational hypermedia is one of these influences which is powered by applications of artificial intelligence and machine learning technologies. In this paper we proposed an adaptive activity sequencing instrument. By applying a novel algorithm and relaxing-based mathematical programming, we achieved to maintain our user model while adapting individual user traits on the web oriented learning activity.
