This paper provides an overview and update on my PhD research project which focuses on integrating learning styles into adaptive e-learning system. The project, firstly, aims to develop a system to classify students' learning styles through their online learning behaviour. This will be followed by a study on the complex relationship between learning styles, learning supports and learning outcomes. The findings can contribute significantly to the area that is still left with several unanswered questions. In addition, based on the results, meaningful recommendations and suitable online adaptation can also be made to a wide range of stakeholders of the education system.
