THE INVESTIGATION OF APTITUDE-TREATMENT INTERACTIONS AS AN INTEGRAL PART OF PROGRAM EVALUATION
One of the primary objectives of public education in the seventies is that of meeting the educational needs of all children through individualization. Despite this goal, little information concerning individual differences in learners is currently available. This paper outlines a schema for the systematic investigation of individual differences in learning through the use of aptitude-treatment interaction studies, and provides an approach to incorporating these studies into an ongoing evaluation system.
