Abstract:

In this experimental study, use of Computer Assisted Instruction followed by the use of an Intelligent Tutoring System (CAI+ITS) was compared to the use of CAI (CAI only) in tutoring students of different learning styles in learning the topic on Algebraic Expression. A total of 62 students participated in the study. One group of 32 students studied algebraic expression in a CAI learning environment, while the other group of 30 students was in a CAI and ITS (CAI+ITS) environment. The students’ learning styles were identified using a questionnaire before the experiment began and they were also given a pre-test on algebraic expression. Post-test was given at the end of the study. The study was administered in eight one-hour sessions. For the first stage of the study, both groups of subjects studied algebraic expression in a CAI environment. In the second stage, subjects from the CAI group went through a tutoring session with CAI, whereas subjects from the CAI+ITS environment continue their study using ITS tutorial. The result of the study showed that both independent variables (learning style and the mode of instruction - CAI + ITS and CAI only), independently of each other, has significant effects on the dependent variable (gain scores). However no significant differences in students’ gain scores were established for the interaction between these two independent variables. The results of the study highlighted some importance on incorporating needs of students with different learning styles in the development of computer-based teaching materials.
