Implications for the Design of Computer-Based Instruction Screens.
Peer reviewed Peer reviewed
Morrison, Gary R.; And Others – Computers in Human Behavior, 1989
Summarizes the results of five studies dealing with screen design for computer-based instruction (CBI) and provides suggestions for their application as well as future directions for research. Chunking, text density, and screen density are discussed as variables in screen design, and current research is described. (33 references) (LRW)

Learner Preferences for Varying Screen Densities Using Realistic Stimulus Materials with Single and Multiple Designs.
Peer reviewed Peer reviewed
Morrison, Gary R.; And Others – Educational Technology, Research and Development, 1989
Discussion of learner preferences for text densities on computer screen displays highlights two studies of college students that compared preferences for multiple or single screen presentations with high-, medium-, or low-density screens from an actual course using computer-assisted instruction. Results are analyzed, and further research needs are…

Morrison, Gary R.; And Others – 1989
Two variables that designers should consider when developing computer-based instruction (CBI) text screens are text density, which manipulates the context of the information presented, and screen density, which is a measurement of the amount of information presented at one time on the screen. A study on text density was designed to identify…

In Search of a Happy Medium in Instructional Technology Research: Issues Concerning External Validity, Media Replications, and Learner Control.
Peer reviewed Peer reviewed
Ross, Steven M.; Morrison, Gary R. – Educational Technology Research and Development, 1989
Proposes directions to help researchers balance instructional technology goals with the performance of well-designed and scientifically sound studies. Issues concerning the external validity of studies, use of media replications, and learner control as a means of adapting instructional strategies to individuals are emphasized, and designs for…

Text Density Level as a Design Variable in Instructional Displays.
Morrison, Gary R.; And Others – Educational Communication and Technology Journal, 1988
Describes study that examined text density levels as a design variable in print and computer-based instructional presentations. The six treatment groups are explained, including low density, high density, and learner controlled density; attitude surveys and achievement posttests are described; and implications of the findings for instructional…

Adapting Text Presentations to Media Attributes: Getting More out of Less in CBI.
Peer reviewed Peer reviewed
Morrison, Gary R.; And Others – Computers in Human Behavior, 1988
Summarizes three research studies on text and screen density variables in a computer based instruction (CBI) lesson. The first two studies investigated the effectiveness of low density text on lessons taught in print and CBI modes; the third study examined learner preferences for different screen densities.
