The article describes a research conducted on students at the University in Pula, by which was attempted to establish whether there is a relationship between exam success and a type of online teaching material from which a student learns. Students were subjected to psychological testing that measured factors of intelligence: verbal, non-verbal and math-logical. Four different teaching resources were prepared for the same educational material. First of those was adjusted for students with the strongest verbal abilities, second for students with the strongest math-logical abilities, third for the students with the strongest non-verbal factor of intelligence. Fourth teaching material was prepared in such a way as to equally represent all three factors of intelligence, for a mixed group of students. Students accessed the online educational material using web courseware tool Moodle. Tests were much better solved by students who had adjusted teaching materials than by students in the mixed group, or those in the control group. This article describes the intelligence tests that were used in the study, structure of the teaching materials and results. (Contains 4 tables.)
