Defines and briefly discusses CBE (computer based education), CAI (computer assisted instruction), CMI (computer managed instruction), and CSLA (computer supported learning aids). CMI and CAI are compared in terms of diagnostic and prescriptive functions, cost-effectiveness, time on learning, and effects on learner attitudes. (JD)

Discusses the use of hypermedia for performance improvement interventions in light of traditional approaches to computer-based training (CBT). Problems with CBT are discussed, hypermedia and hypertext are differentiated, links with data files are explained, hardware selection is discussed, and a comparison of hypermedia systems is presented. (LRW)

Presents background information that describes the major components of an embedded performance support system, compares levels of functionality, and discusses some of the required technologies. Highlights include the human-computer interface; online help; advisors; training and tutoring; hypermedia; and artificial intelligence techniques. (LRW)

Examines one approach to tracking discourse level "functional" features for computer-based writers' aids by comparing the grammatical base and approach to parsing embodied in an ATN parser with that of a systemic parser, which makes an analysis of discourse-level features explicit. (HTH)

Details factors related to the selection of microcomputer systems for computer-based instruction, including cost-effectiveness, instruction improvement and enhancement, and projected use. Descriptions of Apple, Atari, PET, Sorcerer, Terak, Texas Instruments, and TRS-80 are included along with a glossary of microcomputer related terms. (LLS)

This first in a series of articles on organizing electronic network-based instructional interactions describes and compares macro-organizational elements, strategies, and tactics of three popular electronic networks: the FrEdMail Network, the National Geographic Kids' Network, and the AT&T Learning Network. (Contains five references.) (LRW)

Investigates the theoretical basis of the writing process and describes the possibilities of word processing as a tool to support it. Writing process models are compared; the advantages of word processing are discussed, highlighting the revision process; and a model for use by elementary and secondary teachers is suggested. (21 references) (LRW)

Defines courseware engineering (CE) and discusses how it differs from software engineering. Topics addressed include the goals of courseware engineering; a classification of tasks; costs; aspects of knowledge representation; the structure of knowledge in CE; processes in knowledge acquisition; and knowledge base validation. (Contains 48…

Discusses the rationale for sharing courseware between educators, describes the problems of hardware incompatibility associated with software sharing, and introduces a multilingual interpreter system which allows instructional software implemented in different computer languages and on different machines to be shared with a minimum of work. A…

Reports the results of a study conducted at the University of York (England) that was designed to test the effectiveness of a concept mapping tool in aiding student learning from a hypertext-based computer-assisted instruction system. Effects on learning are compared with standard notetaking through results of a posttest. (Contains 17 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…

Explains abductive reasoning; compares it to more traditional forms of logic, i.e., deduction and induction; and describes a computerized tutorial called A.R.T. (Abductive Reasoning Tool) that was created to foster abductive reasoning. Implications of using abductive techniques in instructional design are suggested. (Contains 13 references.) (LRW)

Considers the role and effectiveness of virtual reality in simulation-based training. The theoretical and practical implications of verity, integration, and natural versus artificial interface are discussed; a three-dimensional classification scheme for virtual reality is described; and the relationship between virtual reality and other…

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…

Describes various configurations of computer equipment that can be used in public schools. Labs with multiple computers, one computer in a classroom, and minilabs (with three or four computers on a mobile cart) are compared for cost effectiveness, cooperative learning possibilities, instructional effectiveness, usage, security, and flexibility.…
