The purpose of this study was to examine whether matching navigation mode of a learning environment with learners' preferred navigation mode would facilitate their learning in a web environment. Sixty-eight undergraduate students were randomly assigned to treatments (linear vs. nonlinear navigation mode) and received four criterion tests designed…

The purposes of this study were to determine: (1) the effectiveness with which different types of rehearsal strategies complementing visualized instruction facilitate student achievement; (2) the effect of different instructional treatments on students' processing of different knowledge levels; and (3) whether verbal and visual tests are equally…

Describes a series of studies conducted to determine what types of visuals are most effective in facilitating student achievement. This program of systematic evaluation analyzed an instructional unit on the heart on the basis of instructional effectiveness, economy, and simplicity of production. Conclusions and a list of studies are included. (RAO)

This study examines the effects of four different types of visuals used with television, slide-tape, and programed instruction (printed booklet) presentation. The same script was used with simple line drawings, detailed shaded drawings, photographs of a heart, and photographs of a heart model. In general, results favored programed instruction.…

The effectiveness of elaborate visual cueing and reduced step size (i.e., increasing the number of visual cues) in facilitating student achievement on different instructional tasks was examined. The hypothesis proposed that instructional treatments utilizing reduced step size and elaborate visual cueing alone and in combination would be superior…

The instructional effectiveness of integrating abstract and realistic visualization was studied using five types of visualization, three levels of general ability and two modes of instruction. The dependent variable was performance on a four-part criterion test representing five different types of instructional objectives, which was administered…

Content organization and its effects on prose learning were the focus of this study. Organizational chunking during the encoding or reading interval with an instructional booklet and batched postquestions during the retrieval period (including all events between initial learning and the retention test) were used with 112 university students to…

The effects of intervening synthesis/review sheets, periodic practice worksheets, a combination of review and practice, and an advance organizer on learning from prose text were investigated. Using 161 college students as subjects, the study increasingly added learner activities to an instructional unit (Lamberski's revised edition of the Dwyer…

This study investigated the effects of (1) verbal instruction alone vs. verbal instruction complemented by simple line drawings; (2) visual testing vs. nonvisual testing; (3) verbal cueing vs. free recall on achievement; and (4) order of testing on subsequent achievement. Interactions among type of instruction, type of testing, and order of…

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…

The purpose of several studies was to examine the effects that differentially coded (black and white or color) illustrations had on students who were classified as field independent, field neutral, and field dependent on tests measuring different educational objectives. The effects of visual and verbal test formats were also examined. In general,…

During 12 years of investigation, data were obtained from 2,500 high school students and 10,000 college students concerning the effect of specific types of visualizations in producing optimum levels of achievement. The studies considered such qualities of illustrations as: realism, color, relation to oral presentations, relation to educational…

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…

Describes a study that was conducted to analyze the developmental effects of two instructional strategies--adjunct questions and visualization--in facilitating student achievement among Korean high school and adult learners. Treatments for the experimental and control groups are described, criterion measures are explained, and results are…
