Messages entering an educational information distribution network may be ranked for an ordered introduction into the network to maximize the timeliness of message arrivals over the set of users. Electronic mail, EDI documents, and broadcast news may be ranked by the users who choose to examine those messages of interest or benefit to themselves.…

Teachers of telecommunications, broadcasting, and especially video and film production, are best able to lead the development of computer interactive multimedia instruction. Interactive instruction exists on three levels: (1) a videotape player with rewind, fast-forward, search, pause, and play capabilities; (2) a videodisc or laser disc player…

Papers presented and summaries of discussions at a 3-day conference which focused on screen displays for online catalogs are included in this report. Papers presented were: (1) "Suggested Guidelines for Screen Layouts and Design of Online Catalogs" (Joseph R. Matthews); (2) "Displays in Database Search Systems" (Fran Spigai);…

Social, technological, and economic factors relevant to informed decision-making are presented to provide policymakers with an understanding of factors involved in national entry into videotex and/or teletext technologies. It is assumed that the policymaker has a basic knowledge of computers, but little or no knowledge of the videotex-related…

This report describes the Intelligent Maintenance Training System (IMTS), a set of software tools for composing and delivering simulation-based technical training. The goal in developing IMTS was to generate instructional interactions from device models composed of instances of generic objects. Problem selection in IMTS relies on the use of a…

"Intermedia" is a hypermedia system which was developed for use in university research and teaching. It provides a framework for object-oriented, direct manipulation editors and applications, and the capability to link together materials created with those applications. Instructors are able to construct exploratory environments for their…

This paper reviews briefly the essential characteristics of both invitational education and computer assisted instruction (CAI) and the ways in which coordination of these two models can produce stimulating and valuable educational experiences for students. A matrix illustrates the characteristics of CAI which can support the major values of…

The current attitudes of users and non-users towards public online computer catalogs (OPAC's) were studied at the Library of Congress (LC) and responses were compared with those from an aggregate survey. Attitudes of both users and non-users toward the LC OPAC system were favorable. Problems experienced by patrons related to difficulty in…

This report focuses on a discussion of findings from analyses of computer transaction logs contributed by four of the online catalog systems used in the Public Access Project. It supplements the analyses of User and Non-User Questionnaires by providing analyses of data from the systems themselves. The four systems contributing data to this…

This literature review selectively covers material on end-user searching published between 1971 and 1988. The first section discusses end-user search systems--e.g., multipurpose systems developed for end-users, simplified versions of traditional systems, gateway systems, and CD-ROM versions of databases. This section also discusses the complexity…

This history of computer text analysis of student writing while brief, is complicated by the fact that there are actually three distinct efforts underway to use the computer for such purposes. There is a certain amount of overlap among the efforts, but their intentions are different enough to warrant separate review. The first effort is toward…

This paper describes the Grolier Publishing Company's development of its encyclopedic text database by editing the machine-readable data files from which the Academic American Encyclopedia was printed, and its longer-term objective of creating a multimedia encyclopedia when the technology for a viable delivery system becomes available. Topics…

Designed to facilitate and increase the interaction of college administrators with automated systems, this guide addresses three basic questions: what is the value of technology in an institution; what is the priority of technology in relation to other aspects of the institution; and what is the commitment to technology as reflected in the…

Transactional Analysis (TA) of teaching and learning process reveals actions and reactions triggered from the ego-states of teacher and learner. The teacher has to switch between these ego-states to achieve effective communication and learning results. Ego-states of teacher and learners are worth studying in the context of e-learning, as the…

The first phase of a project to design a prompting system to help semi-experienced end users to search Chemical Abstracts online, this study focused on the differences and similarities in the search approaches used by experienced users and those with less expertise. Four online searches on topics solicited from chemistry professors in small…
