Personalized E-learning Environment Using Fuzzy Recommender System base on Combination of Learning Style and Cognitive Trait

Personalization needs to identify the learnersʹ preferences and their characteristics as an important part in any e-learning environment which without identify learnersʹ mental characteristics and their learning approaches, personalization cannot be possible. Whatever this identifying process has been done more completely and more accurately, the learner model that based on it will be more reliable. Using the combination and relation of effective theories in learning approaches detection such as learning style and cognitive trait, have been used in this research. Also for reducing ambiguity in learnersʹ opinions and their feedbacks, have been used fuzzy logic. This study was conducted during one semester on some e-learning students in engineering field based on fuzzy recommender system in two phases. This recommender is part of Intelligent Tutoring System as prepared some recommendations based on learning style in first phase and on half of courses and in second phase and on remaining courses, prepared recommendations based on combination of two mentioneed theories. Learnersʹ ability have been monitored and evaluated based on fuzzy item response theory in all steps. Measures of Intelligent Tutoring System have been optimized after this combination that clarifies the presentation of accurate recommendations in appropriate time. The time of effective learning and amount of referee to tutor have decreased, learnerʹs and tutorʹs view to e-learning that define such as learnersʹ success rate and the learnerʹs satisfaction have improved increasingly.
