Abstract
To obtain required effects of Web-based learning process, teaching environment should be adjusted to student needs. Differentiation of the environment features can be received by grouping learners of similar preferences. Then each new student, who joins the community, should obtain the recommendation of the group of colleagues with similar characteristics. In the paper, we consider using fuzzy logic for modeling student groups. As the representation of each group, we assume fuzzy numbers connected with learner attributes ranked according to their cardinality. Recommendations for new students are determined taking into account similarity of their dominant features and the highest ranked attributes of groups. The presented approach is examined, for students described by learning style dimensions. The method is evaluated on the basis of experimental results obtained for data of different groups of real students.
