THE INTEGRATION OF WORDS AND PICTURES IN THE TWO STUDIES REPORTED IN THIS VOLUME WAS ACCOMPLISHED UNCONVENTIONALLY. IN ONE STUDY, AN ENTIRE TOPIC, ARCHIMEDES' LAW, WAS COVERED IN A SELF-CONTAINED, ENTIRELY PICTORIAL LESSON AND ALSO IN A SELF-CONTAINED, ENTIRELY VERBAL LESSON. STUDENTS ACQUIRED ALL THE CONCEPTS AND PRINCIPLES MAKING UP ARCHIMEDES' LAW FIRST ON THE BASIS OF ONE LESSON AND THEN ONCE AGAIN ON THE BASIS OF THE SECOND. IN A SECOND STUDY INVOLVING A LESSON ON PRESSURE, ONLY ONE OR TWO CONCEPTS OR PRINCIPLES WERE COVERED IN EACH VISUAL SEGMENT AND THEN AGAIN IN EACH VERBAL SEGMENT. IT REQUIRED ALL FIVE VISUAL SEGMENTS IN THE LESSON TO TEACH ALL THE CONCEPTS AND PRINCIPLES. SIMILARLY IT TOOK ALL FIVE VERBAL SEGMENTS TO TEACH ALL THE CONCEPTS AND PRINCIPLES. THE ONLY DIFFERENCE BETWEEN THE TWO STUDIES WAS THAT THE LESSON IN THE SECOND STUDY WAS SEGMENTED. WHAT WAS COMMON TO BOTH STUDIES WAS THE PROVISION FOR THE ACQUISITION OF THE DISCRIMINATIONS AND GENERALIZATIONS UNDERLYING THE CONCEPTS AND PRINCIPLES TO BE TAUGHT SOLELY ON THE BASIS OF PROGRAMED VISUAL MATERIAL, AND THEN ON THE BASIS OF BOTH SETS OF MATERIALS COMBINED.
