An Evaluation of Award-Winning Elementary Teaching Materials from the Kazanjian Program

In an unusual study, Professor Nappi attempts to measure the effectiveness of teacher-made materials in increasing the economic knowledge of elementary school pupils. In addition, he asks whether special training for teachers using the materials results in greater pupil learning as well. Finally, he seeks to determine the extent to which the teacher's understanding of economics (as measured by the Test of Economic Understanding published by Science Research Associates) brings about a change in pupil knowledge. Experimental and control groups were established for purposes of this study, and the pupil change scores were adjusted for differences in mental ability. It was found that, ceteris paribus, the materials, the special training for teachers, and teacher knowledge of economics all resulted in “comparative advantages” for experimental group pupils.
