The Teacher-Interactive Computer System (TICS) is an on-line and interactive programing system for authoring interactive programs, particularly instructional programs. The system provides a fairly natural language, in which the author's statements for creating items in a program, for examining the structure and flow, for simulating its use by…

A questionnaire was designed to aid the interested professional in describing, characteristics and analyzing his game, model, or simulation, and tested on a number of Department of Defense (DOD) games. An over-riding goal for the questionnaire was to produce a categorization scheme for games in general. The different sections of the questionnaire…

An Information System for Vocational Decisions (ISVD) is described and discussed. The system is intended to accommodate, in potential, the vocational needs of users extending from kindergarten to retirement. With ISVD, occupational facts/data can be converted into vocational information by means of personal inquiry which is at least initially…

The evolution of a self-contained test scoring terminal is presented. The rationale for the design is presented along with an evolutionary description of the requirements for the system. The sequence of software and hardware tools, which were developed in order to build the device, are also described in this report. The resulting device, which…

Discussed is a simulation game designed to acquaint environmental planners and resource managers with the problems and interactions involved in an environmental system. A description of the structure, rules, and dynamics of the game is presented. Also included are recommendations and an example of the game. (MR)

This state of the art paper on CBI considers problems facing the development of CBI, and offers suggestions on how practitioners can strengthen its impact in education through research in artificial intelligence and related areas of human motivation and learning theory, as well as innovative techniques in human-machine interfacing. (RAO)

Presents a model for information retrieval evaluation based on the notion of total relevance, a function derived from the traditional summation of relevance ratings over the documents in a collection. The model makes explicit the perceptual underpinnings of relevance assessments while allowing for consideration of interdocument dependencies. (37…

Examines the functional characteristics of intelligent computer assisted instruction (ICAI) and discusses the requirements of a multidisciplinary cooperative effort of its development. A typical ICAI model is presented and intelligent features of ICAI systems are described, including modeling the student's learning process, qualitative decision…

Comparison of the use in libraries of open systems--a configuration of software and hardware components from separate vendors linked by interfaces--and integrated systems considers selection of services; reliability; relationships with vendors; time needed to implement systems; and overall effectiveness of both approaches. (CLB)

Discusses whether techniques found useful in text design can be transposed to the display of computer-assisted learning (CAL) materials. Highlights include differences in interaction between books and computers; problems in learning from books; text displays; computer displays; and possible future developments. (Author/LRW)

Examines the role of human information processing and decision-making capabilities and limitations in the design of effective human-computer interfaces. Several cognitive engineering principles that should guide the design process are outlined. (48 references) (Author/CLB)

Presents a list of recommended practices for designing computer-based instruction courseware based on principles derived from learning research. Research-based principles and the corresponding design practices are outlined for the areas of stimulus design, learner responses, feedback, and lesson control. (6 references) (CLB)

This article analyzes the front end software marketplace and discusses some of the complex forces influencing it. Discussion covers intermediary market; end users (library customers, scientific and technical professionals, corporate business specialists, consumers); marketing strategies; a British front end development firm; competitive pressures;…

Discusses ability of small computers to hold interface programs, to retrieve data from central source, to manipulate and present that data, and to engage in dialog with system user. An example of a feasible dialog between user and system which mediates and translates user's data into machine terms is highlighted. (EJS)

Explains rationale behind proposed voluntary U.S. standard computerized library catalog called the "Uniform Catalog." Design goals (should mimic manual card catalog, offer simplicity of operation and low overhead, permit modular growth to more advanced catalog), sample search, and nine commands and functions used by "Uniform…
