Interactive Study Lessons to Complement ANOVA.
Johnson, Craig W.; Plake, Barbara S.
This project developed and evaluated a series of interactive study modules for students taking a course in Analysis of Variance (ANOVA) techniques using the IBM Interactive Instructional System (IIS) software. Exercises were general enough to be applicable across a variety of research areas. The computer assisted instruction (CAI) approach was particularly appropriate for this type of material because of the hierarchical nature of the steps involved in ANOVA procedures. Graduate students enrolled in advanced statistical methods were required to complete each interactive lesson as they progressed through the course. Four classes over four years of implementation were evaluated by midterm and final unit exams for the course, course evaluation, and module evaluations. In terms of satisfaction and effectiveness, students ranked modules second only to the class lectures as a whole and far above the textbook and independent practice. There were significant increases in unit examination performance after module implementation. Initial responses of anxiety and apprehension concerning the computer environment yielded as student became familiar with the system. (Author/RL)
