This paper explores languages for communicating precise ideas within limited domains, which include mathematical notation and general purpose and high level computer programming languages. Low-level properties of such natural artificial languages are discussed, with emphasis on those in which names are chosen for concepts and symbols are chosen…

The literature on instructional design argues that curricula, educational materials, and instructional strategies are best created using a systems approach, and models for the systematic design of educational programs have proliferated over the past decade. However, these models are prescriptive and not based on research into how designers…

The report on preliminary administration of the AEBLE (Assessment of Environmental Barriers to Leisure Experiences) instrument to 18 orthopedically impaired children reveals five factors (all but the family support) to be considered problems: community reaction resources, architectural barriers, accessible and available transportation, community…

This column discusses the problem of character standard for computer keyboard, screen, and printer in relation to foreign language capability. Some solutions are offered, such as built-in screen flexibility, a graphics adapter with "font downloading" capability, and a new, relatively inexpensive graphics board--the multifont by Hash-Tech. (AMH)

Discusses the concept and design of an enriched learning and information environment that was originally developed at Indiana University in partnership with AT&T (American Telephone and Telegraph). Topics addressed include constructivism, cognitive tools, representing expert behavior, apprenticeship, technological tools, information tools,…

Based on literature and student input, six major concerns have been noted for student programming progress for the academic class and work environment. The areas of concern are module driver programming, program documentation, output design, data design, data validation; and reusable code. Each area has been analyzed and examined in the teaching…

This summary of methods for improving the user-computer interface is based on a review of the pertinent literature. Requirements of the personal computer user are identified and contrasted with computer designer perspectives towards the user. The user's psychological needs are described, so that the design of the user-computer interface may be…

Because the Navy needs tools to assess the personnel implications of proposed equipment and system designs, a literature search was conducted in 1978 to determine how hardware design engineers perceive the relationships between system design characteristics and the skills of the system operator and maintenance personnel. Recent studies conducted…

The development and evaluation of a potential viewdata-style delivery system for computer assisted learning (CAL) at the Open University are described. First examined are Open University problems with CAL and television delivery systems, which resulted in the consideration of a viewdata approach involving allocation of a small central processor to…

Discusses text displayed on computer screens and examines the effects of three layout variables--justification, line length, and leading--on reading speed and comprehension. Current literature on each variable is reviewed, and implications for the design of computer-based instruction are presented. (Author/LRW)

Presents results of five experiments on human information-seeking behavior in different online information-seeking environments which studied search strategies and assessed information value in realistic search environments. A conceptual model of how humans value information is presented. Empirical and modeling results are considered for…

Discusses the importance of recognizing the human component in library automation systems to ensure the smooth and efficient operation of the system. Human factors considerations are discussed in terms of health and safety aspects, ergonomics, workplace design, and job organization. (41 references) (CLB)

Examines methods of lecturing in the past, including blackboards, whiteboards, flip charts, and overhead transparencies; discusses the increasing use of computer technology and specifications for future systems; and describes possible scenarios for future lecturing technologies, including the generation of computer-assisted instructional materials…

Describes factors to be considered in the design of ergonomically correct workstations for online searchers. Topics discussed include visual factors, including lighting; acoustical factors; radiation and visual display terminals (VDTs); screen image characteristics; static electricity; hardware and equipment; workstation configuration; chairs;…

This brief fact sheet addresses the following concerns about effective communication and accessibility under the Americans with Disabilities Act (ADA): requirements under the ADA for achieving effective communication (e.g., provision of necessary auxiliary communication aids and services); identification of necessary communication aids and…
