Evaluating the Impact of Adaptation to Learning Styles in a Web-Based Educational System

Measuring the effect of providing educational experiences individualized to the learning style of the students is an open research issue. This paper aims at presenting a case study of a dedicated adaptive educational system called WELSA. First, the adaptation logic, methods and techniques employed in WELSA are briefly presented. Next, the validity and effectiveness of the system are assessed by means of an empirical evaluation approach, involving two experiments with 64 undergraduate students. The results obtained (in terms of learner behavior, performance, efficiency and satisfaction) are analyzed and discussed. The overall results of the experimental study indicate a positive effect of adaptation to learning styles on the learning process.
