Describes methodology and results of a study examining the role of layout and graphic design in the legibility of instructional text displayed on cathode ray tubes. This report includes a multidimensional scaling analysis, an analysis of the stimuli and independent variables, and labeling and dimensions using adjective and interview data. (MBR)

This study was conducted to determine if viewing a commercially prepared videotape containing written and aural subliminal messages was more effective at producing weight loss than a videotape containing the same content, but without the subliminals. Participants included undergraduate and graduate students from Iowa State University (N=51) who…

Effectiveness of two versions of computer software used as an electronic blackboard to present geometric concepts to ninth grade students was compared. The experimental version incorporated color, animation, and nonverbal sounds as stimuli; the no-stimulus version was monochrome. Both immediate and delayed learning were significantly better for…

This study investigated the use of word-visuals to aid university students' recall by examining relationships that exist among levels of learners' recall resulting from different presentation modes; between levels of field-dependent and field-independent learners' recall; and between levels of field-dependent and field-independent learners' recall…

The proposal put forward in this presentation centers on the use of the microcomputer for the generation of educational research, both as a powerful tool for information collection and as a means for analyzing the generated data. The microcomputer-based laboratory (MBL) principles described in this paper may be used in rural classroom settings as…

This investigation evaluated performance of university students on visual and nonvisual versions of an achievement test. Two experimental designs assessed the effects and interactions between visual and nonvisual instructional modes, order of drawing test (before or after verbal/visual achievement test), and mode of drawing test (verbal cued or…

Describes the third in a series of studies investigating effects of psychological variable of encoding specificity on cognitive learning, test design, and visualization during instruction and testing. Encoding specificity, its application to classroom learning and testing, and its significance to educational technology are explained. The first two…

This exploratory study was conducted to investigate the potential interaction between the media attribute, horizontal screen placement, and a learner's cognitive aptitudes, fluid ability, and visualization. The primary hypothesis tested was that low-ability learners who are without well-developed assembly and control operations should perform…

This study investigated effects of rehearsal strategies and immediate test formats on delayed retention and effectiveness of visualization on material acquisition and retrieval. Findings indicate different rehearsal methods have different effects in facilitating delayed retention. Information acquisition is facilitated by visualization, although…
