In this volume, the results of a study of concept learning are presented. (The background for the study, and descriptions of the treatments--rote reception, rote discovery, conceptual reception, and conceptual discovery--are provided in Part 1.) Several hypotheses concerning the effectiveness of these treatments in learning concepts and on the ability to use those concepts were analyzed using multivariate analysis of covariance. The results of these analyses indicated some differences for the reception and discovery treatments, and for the rote and conceptual treatments; no interaction between these dimensions was discovered. The data are shown to fit well with the Bower model for paired-associate learning. (SD)
