Article
With the increased emphasis on the benefits of self-regulated learning (SRL), it is important to make use of the huge amounts of educational data generated from online learning environments to identify the appropriate educational data mining (EDM) techniques that can help explore and understand online learners’ behavioral patterns. Understanding le...

Learning Management Systems lack automated components that analyze data and generate information on leaner behavior. Manual methods involving administering questionnaire related to a specific learning style and cognitive psychometric tests have been used to identify such behavior. The problem with such methods is that a leaner can give inaccurate i...

Abstract: Adaptive e-learning promises to deal with the problems of not considering learner characteristics experienced in e-learning systems. Research has shown that adaptive e-learning improves the effectiveness of e-learning systems and removes the loneliness experienced by learners when they are online. Though this is the case,adaptive e-learni...
