THIS IS A REPORT OF TWO STUDIES IN WHICH PRINCIPLES OF PROGRAMED INSTRUCTION WERE ADAPTED FOR VISUAL PRESENTATIONS. SCIENTIFIC DEMONSTRATIONS WERE PREPARED WITH A VISUAL PROGRAM AND A VERBAL PROGRAM ON--(1) ARCHIMEDES' LAW AND (2) FORCE AND PRESSURE. RESULTS SUGGESTED THAT RESPONSES ARE MORE READILY BROUGHT UNDER THE CONTROL OF VISUAL PRESENTATION WHEN STUDENTS RESPOND ACTIVELY THAN WHEN THEY MERELY WATCH PASSIVELY. THESE RESULTS PROVIDED THE BASIS FOR PRACTICAL CONCLUSIONS REGARDING THE TEACHING OF CONCEPTS AND PRINCIPLES BY FILM OR TV LESSONS--(1) PICTORIAL MATERIALS SHOULD BE PROGRAMED TO BE CAPABLE, ON THEIR OWN, OF TEACHING CONCEPTS, (2) DURING SUCH PRESENTATIONS, DISCRIMINATION PRACTICE SHOULD BE BASED ON PICTORIAL RESPONSE OPTIONS, AND (3) PROGRAMED PICTORIAL MATERIALS SHOULD PRECEDE THE ACCOMPANYING VERBAL MATERIALS. OTHER REPORTS IN THIS SERIES HAVE ACCESSION NUMBERS ED 003 211 THROUGH ED 003 213. (JM)
