Intelligent Tutoring Systems and cognitive abilities

Intelligent tutoring system (ITS) is a computer software that provides customized instructions to students according to their learning style, knowledge, and abilities. In reality, most of the existing ITSs do not consider individual cognitive differences and try to teach students primarily on the basis of their domain knowledge and performance. Several cognitive tests [38, 39, 40, 41, 42, 43] are available that measure different cognitive abilities of individuals which make it possible to identify individual differences. In this paper we present a methodology for an ITS that provides individualized environment and teach students according to their cognitive abilities. A prototype has been developed and tested to prove the effectiveness of this methodology. The data analysis shows that the students who were taught according to their cognitive abilities performed significantly better than those who were not provided with teaching material as per their cognitive abilities.
