Evaluation

Abstract

In this chapter the evaluation of the hybrid student model F.O.S., which incorporates fuzzy logic techniques, is presented. The presented evaluation process is performed applying the evaluation framework PERSIVA (Chrysafiadi and Virvou 2013a), which includes both questionnaires and observations through experiments. In particular, either the educational impact (i.e. performance, satisfaction, change of learners’ attitudes) or the effectiveness and validity adaptation of the personalized and/or adaptive tutoring system are assessed. The evaluated hybrid student model was integrated in a programming tutoring system for the programming language ‘C’. Students of a postgraduate program in the field of Informatics on the University of Piraeus, Greece, used the particular system to learn how to program with the programming language ‘C’. The evaluation results were very encouraging. They demonstrated that the presented student modeling approach had a positive impact on the learners’ performance and on the learning process. Furthermore, they showed that the system made valid and meaningful adaptation decisions.
