PERSONALIZED E-LEARNING SYSTEMS: A USER MODELING TECHNIQUE

Abstract

For providing the personalization feature to e-learning systems, a Human ComputerInteraction HCI technique, User Modeling was considered in system design. This study wasundertaken to propose a technique to model the students’ learning styles for personalized e-learningsystem. Bayesian Network BNwas used to model the students’ learning styles and Kolb’s learningstyles theory was used to know the students’ learning styles and preferences. The objective of the studywas to propose a user modeling technique for personalized e-learning systems to understand the elearners’ requirements and needs to enhance their learning.Using BN, Conditional Probability Tables CPTs were determined for all four learning styles provided by Kolb’s theory. The threshold values were used to determine the learning styles of students during an online course. We found that BN technique determined successful as from the Divergers 100%., 75% Assimilator, 50% Accommodatorsand 75% Convergers were identified accurately.
