A Comparison of Learning Environments: All That Glitters... Interim Technical Paper for Period January 1990-July 1991.
Shute, Valerie J.
Aptitude-treatment interactions (ATIs) refer to the covariation between learner characteristic and instructional treatment in relation to some outcome measure. To systematically test for ATI, an intelligent tutoring system instructing in basic principles of electricity was chosen as a complex but controlled learning task. Two learning environments were created from this one tutor, differing only in feedback. In the rule-application environment, the system provided learners with relevant principles, and in the rule-induction environment, learners had to induce principles on their own. Subjects were 309 adult high school graduates approached through a temporary employment agency. The learner characteristic examined was exploratory behavior, a measure of on-line tool usage. It was hypothesized that exploratory learners would learn faster and better if they had been assigned to the inductive environment and fewer exploratory learners would benefit from the more structured application environment. Results show significant aptitude-treatment interactions in the data, confirming the hypothesis. Implications are discussed in relation to the design of intelligent tutoring systems. Eleven figures and six tables illustrate the discussion and present study findings. (Contains 30 references.) (SLD)
