A total of 1100 students participated in the study by enrolling in Introductory Psychology 101 in Fall '94 or Spring '95 semesters. In all important technical respects, the two groups differed only in terms of the type of instruction received. PSI was found to be superior to the lecture method on all measures taken of student achievement and satisfaction. Students in PSI reported that they improved in self-management and study skills, understood that material, enjoyed the course, accomplished their goals, and so on in numbers that far exceeded the students receiving the lecture method. The proven superiority of PSI ensures that it will replace the lecture method in all introductory courses in the Department of Psychology at the University of Nevada.
Plans are underway to replicate the study in other departments that offer large enrollment courses.
Additional research will follow a cohort of students who received both types of instruction to determine how well they remember the courses content, how they are performing in other course, and so on. At the top of the list of priorities for both the Department and the University is to explore how computer technology and PSI can be wed.
