The Effects of Interactive Graphic Analogies on Recall of Concepts in Chemistry.

Two versions of a CAI lesson on how a simple battery works were designed to elaborate conceptual and topographic information either verbally or pictorially. The effects of the type of information presentation on learning and attitudinal outcomes was investigated. Subjects in the treatment providing external imagery reported experiencing more internal imagery than did the group receiving the verbal version. The possibility of an interaction between eye-movements during tests of verbal and pictorial processing and attitudes toward the two CAI lessons was suggested by the data. These outcomes are generally supported by the literature on mental imagery in learning and memory.
