AN INVESTIGATION OF THE RELATIVE EFFECTIVENESS OF CERTAIN SPECIFIC TV TECHNIQUES ON LEARNING. FINAL REPORT.
SCHWARZWALDER, JOHN C.
GOAL OF THIS STUDY WAS TO ASSESS THE EFFECTS OF CERTAIN AUDITORY AND VISUAL STIMULI PRESENTED BY EDUCATIONAL TV. SPECIFIC QUESTIONS ASKED WHETHER VISUAL REINFORCEMENT, CONTINUITY, AND MANIPULATION TECHNIQUES INCREASE MASTERY OF SCIENCE INFORMATION BY FIFTH GRADERS. 72 TV LESSONS IN 9 AREAS OF SCIENCE, VARYING COMBINATIONS OF THE 3 TECHNIQUES AT EACH OF 2 LEVELS, WERE PRODUCED. CLASSROOM, INSTRUCTORS, EQUIPMENT, SELECTION, AND TESTING VARIABLES WERE CONTROLLED. A FACTORIAL DESIGN TO TEST EFFECTS OF THE TECHNIQUES AND THEIR INTERACTIONS BY ANALYSIS OF VARIANCE WAS EMPLOYED. FOR 40 CLASSES, PRE-TEST SCORES OF MENTAL ABILITY WERE USED AS COVARIATES WITH IMMEDIATE POST-TEST SCORES OF ACHIEVEMENT. THE AUTHORS USED THE .10 LEVEL OF SIGNIFICANCE BECAUSE EDUCATIONAL TV RESEARCH WAS A NEW AND UNREFINED FIELD. MISSING DATA WERE PREDICTED FROM A REGRESSION EQUATION. 22 OF THE 63 DIFFERENCES WERE REPORTED AS SIGNIFICANT. OF THESE 20 WERE SIGNIFICANT AT THE .05 LEVEL. MOST OF THESE DIFFERENCES IN ACHIEVEMENT RESULTED FROM INTERACTION OF TWO TECHNIQUES, SHOWING THAT THE TV APPEARED TO FACILITATE TEACHER EFFORTS. IMPLICATIONS FOR FURTHER RESEARCH ARE DISCUSSED. (LH)
