Learning Through Advocacy: An Experimental Evaluation of an Adversary Instructional Model

Dr. Kourilsky describes the use of her Adversary Instructional Model and reports on an experiment in which the Model was used in high school economics classes. Control and experimental groups were tested with the Watson-Glaser Critical Thinking Appraisal, the Dietz Test of Economic Understanding and a specially designed Attitude Rigidity Inventory or “opinion ballot.” Some of the results are surprising, but the superior performance of the experimental group on the Watson-Glaser test strongly suggests that the Adversary Instructional Model is a valuable instructional device.
