Explains how standardizing computer system hardware and software throughout the school campus can increase efficiency; reduce costs and acquisition lead time; and make training, technical support, and hardware replacement and repair easier. Questions to ask when choosing among different hardware and software systems are highlighted. (GR)

Presents a group of semiotic principles for software design and uses them to show how they explain different educational possibilities. Discusses interface design and describes Theater in the Computer, a software environment for children, to illustrate semiotic-based principle of interface design. (Author/LRW)

A study examined students' thinking processes when using database applications to solve an ill-structured business problem and compared six students using command language with six using menu selection computer interfaces. Students used a subgoal analysis method for problem solving. Command language group was more likely to skip relevant factors…

Computer tracking data were used to determine the relationship between effectiveness and efficiency of 94 students using a database program for instructional tasks. Performance was enhanced by review of rules and presentation forms; additional practice opportunities also benefitted performance. (Copntains 19 references.) (JOW)

Examines metaphor's limitations as a visual-rhetorical framework for designing, evaluating, and critiquing user interfaces. Outlines an alternate framework for visual rhetoric, that of genre ecologies, and discusses how it avoids some of the limitations of metaphor. Uses an empirical study of computer users to illustrate the genre-ecology…

Discusses the use of icons in computer interface design. Highlights include picture processing time, complexity, recognition memory, differences between picture icons and picture/text icons, the use of color, size, placement, and touch design. (LRW)

Describes the development of production requirements and technical specifications for a microfilm-to-digital conversion project that digitized early English books printed between 1475-1700. Discusses the Internet interface used for access; MARC records; indexing; partnerships with libraries and universities; scanning; database design; and quality…

Includes three articles that discuss activity theory, based on "Context and Consciousness." Topics include human-computer interaction; computer interfaces; hierarchical structuring; mediation; contradictions and development; failure analysis; and designing educational technology. (LRW)

Discusses usability in the context of creating distance learning or computer-based training environments and describes a three-step approach to learner-centered usability testing. Highlights include functions of the instructional interface that should be similar to a responsive teacher; elements in the learning environment; and testing it via a…

Presents a proposed information environment (PROPIE) for enhanced interaction and value-adding of electronic documents that allows users multiple ways to query intuitively and navigate information in an electronic document. Highlights include user interface technologies; visualization and interactive techniques; query and browsing processes; and…

The interfacing of various spectrometers with analog output to a personal computer running Microsoft Excel in the Windows environment is described. This low cost data acquisition solution is a useful replacement of a chart recorder for various UV-visible and infrared scanning spectrophotometers.

Searching for icons, symbols, or signs is an integral part of tasks involving computer or radar displays, head-up displays in aircraft, or attending to road traffic signs. Icons therefore need to be designed to optimize search times, taking into account the factors likely to slow down visual search. Three factors likely to adversely affect visual…

The inability of computer users who are visually impaired to access graphical user interfaces (GUIs) has led researchers to propose approaches for adapting GUIs to auditory interfaces, with the goal of providing access for visually impaired people. This article outlines the issues involved in nonvisual access to graphical user interfaces, reviews…

Background: Palmtop computers provide a promising mobile platform to address barriers to computer-based supports for people with intellectual disabilities. This study evaluated a specially designed interface to make navigation and features of palmtop computers more accessible to users with intellectual disabilities. Method: The specialised…

The Web puts a huge number of learning resources within reach of anyone with Internet access. However, many valuable resources are difficult to find due to the lack of interoperability among learning repositories. In order to achieve interoperability, implementers require a common query framework. This paper discusses a set of methods referred to…
