The Establishment of the Validities of Experimental Materials in Geography

Abstract

This paper describes the various procedures followed in validating some research tools to be used to investigate pupils' attitudes toward and achievements in geography taught by programmed instruction. The research tools consist of learning materials and measuring instruments. The learning materials include five geography programmed texts, five conventional texts in geography, and a familiarization program in civics. The measuring instruments also include a geography achievement test, and two attitude questionnaires designed to measure attitudes toward geography and programmed instruction. The paper highlights the roles of formative evaluation in preparing curriculum materials in geography.
