As graphically driven, animated, interactive applications offer educators new opportunities for shaping course content, new avenues for research arise as well. Along with these developments comes a need to study the effectiveness of the individual tools at our disposal as well as various methods for integrating those tools in a classroom setting.…

SEVERAL CONCLUSIONS FROM RESEARCH ON VISUALS ARE DISCUSSED. THE PARTICULAR STUDIES ON WHICH THESE CONCLUSIONS ARE BASED ARE TWO MULTIVARIATE EXPERIMENTS WHICH USED PROGRAMED SCIENCE DEMONSTRATIONS PRESENTED OVER TELEVISION AND PROGRAMED VERBAL MATERIALS ON THE SAME SCIENCE PRINCIPLES BUT PRESENTED IN SELF-PACED BOOKLETS. THE LEVEL OF THE…

TWO DIFFERENT USES OF VISUAL REPRESENTATIONS FOR SCIENCE INSTRUCTION WERE INVESTIGATED. THE FIRST STUDY EXAMINED THE HYPOTHESIS THAT USE OF PICTORIAL INSTRUCTION WOULD PRODUCE HIGHER CORRELATION BETWEEN RESULTS OF VISUAL APTITUDE TESTS AND LEARNING TESTS, AND THAT VERBAL INSTRUCTION WOULD PRODUCE HIGHER CORRELATION BETWEEN RESULTS OF VERBAL…

SLIDES OF SELECTED TEXTBOOK ILLUSTRATIONS, DRAWN TO HIGHLIGHT THE PERTINENT AREAS OF THE ILLUSTRATION BY MEANS OF SHADING AND ILLUMINATION, WERE USED TO EVALUATE THEIR EFFECTIVENESS OVER SELECTED SLIDES OF CONVENTIONAL ILLUSTRATIONS AND DIAGRAMS IN WHICH ALL DETAILS WERE PROMINENTLY DISPLAYED. WHEN THE CONTROL SLIDES WERE PRESENTED, A TEACHER USED…
