Interactions between Structure-of-Intellect Factors and Two Methods of Presenting Concepts of Modulus Seven Arithmetic: A Follow-up and Refinement Study

The purpose of this study was to replicate and generalize the findings of two earlier ATI studies. 205 Ss were pretested for cognitive ability and then were randomly assigned to 1 of 2 treatments (figural vs. verbal) on a unit in modulus seven arithmetic. Subjects were given 1 class period to study the programmed material and 1 week later retention and transfer tests were administered. The results did not support the earlier findings in this area and indicate that perhaps more investigation in the area of aptitude test construction might be justified. Although not limited to the ATI area, the results indicate that more replication studies are needed before we begin to weigh first results too heavily.
