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)

Discusses the use of artificial intelligence (AI) in education and describes intelligent tutoring systems (ITSs). Knowledge representation and AI are discussed; differences between ITSs and traditional computer-assisted learning (CAL) are explained; and research that has contributed to ITSs from the fields of education, psychology, cognitive…

Reviews what has been learned about the use of motivational and informational feedback in traditional instruction, examines how this knowledge may be useful in the design of feedback for computer-based instruction (CBI), and discusses the relationship between feedback and learning outcomes. Further research needs are suggested. (13 references)…

Discusses research on the effectiveness of computer-based instruction (CBI) and proposes computer modeling as a tool to redirect CBI research toward more theoretically relevant and prescriptive research. Limitations of media comparison studies and media replication studies are described, and computer modeling in CBI research is reviewed. (48…

This paper discusses media comparison studies and reasons that research of this nature is pursued, especially in the area of computer-based interactive video (CBIV). Three scenarios are presented to demonstrate instances in which the knowledge of the relative effectiveness of CBIV is important and useful: (1) the case of the administrator who…

Examines expert system shells and the role a microcomputer-based expert system can play as an intelligent job aid. Characteristics of traditional and automated job aids techniques are described, and the role of instructional designers in developing expert systems within organizations is discussed. (Author/LRW)

This paper explores the realm of evaluation within the domain of Intelligent Tutoring Systems (ITS). Toward that end, Littman and Soloway (1988) described two facets of evaluation: external and internal. Described here are a variety of procedures that they did not address and some that they discounted. One of the procedures not explored was the…

Describes three studies conducted at Pennsylvania State University to determine the effects on achievement and student satisfaction of various ratios of questions or highlights to text in computer assisted instruction (CAI) modules; question or highlight placement; and having questions or highlights on same or following page of target text. (MBR)

Describes a study that examined the relationship between academic ability or aptitude, as measured by grade point average and American College Test scores, and achievement with and without computer-assisted instruction. (15 references) (CLB)

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…

A review of computer assisted instruction research and recent meta-analytical reports suggests that all research on the learning benefits of the instructional uses of computers should be halted until there is a plausible reason to expect that computers are instrumental in learning, since all existing evidence indicates that computers do not yield…

Discusses the shift in core curriculum materials from printed textbook formats to electronic formats. Highlights include cooperative learning; teacher-student interaction; multimedia-based programs; changes in the media development process; different versions of the final product; new revision schedules; and permission to use visual images, sound,…

Reports on ways in which interactive video-based courseware is being used with students studying for vocational qualifications at Thames Valley University (United Kingdom). Two alternative models using interactive video are described, one using multiple workstations and one using a single workstation led by a tutor. (Contains six references.) (LRW)

Discussion of cognitive apprenticeships highlights a computer-based coached practice environment called SHERLOCK that was developed for Air Force technicians. Training for complex skills is discussed, comparisons are made between results with SHERLOCK and results with apprenticeship models that have human coaches, and possible future enhancements…

Discussion of the degree of training effectiveness in management training technologies focuses on a training experiment which employed two scenarios of a computer assisted simulation. Structural components of managerial effectiveness versus specific content of managerial tasks are described, and suggestions for future training technologies are…
