A Note on the Importance of Studying Class Effects in Aptitude-Treatment Interactions.
Results pertaining to methodological aspects of an aptitude-treatment interaction study are presented. One treatment group in the study was given imagery instructions, the other had no imagery instructions. Each treatment group consisted of seven fifth-grade classes. Among the aptitude variables there were two versions of a paired-associates learning task. Within-class analyses and analyses where class effects were allowed to have influence were conducted. In the latter analyses there were several significant aptitude-treatment interactions with subscores derived from the paired-associates tasks, but this was not the case in the within-class analyses. The interactions found are interpreted as being consequences of class effects with respect to the errors of measurement. (Author)
