Built-in data structures are the registers and memory words where binary values are stored; hard-wired algorithms are the fixed rules, embodied in electronic logic circuits, by which stored data are interpreted as instructions to be executed. Various topics related to these two basic elements of every computer program are discussed. (JN)

Discusses four types of computer programs that can manipulate linguistic symbols with great facility. These programs deal with: (1) machine translation; (2) word processing; (3) question answering; and (4) adjuncts to electronic mail known as coordination systems. Also considers the future of computer software dealing with language. (JN)

Interactive computer graphics is fast becoming the standard medium of communication between computers and all kinds of users. Reasons for this trend, the technology of interactive graphics displays, software considerations, applications (including classroom and laboratory applications), and future developments are discussed. (JN)

Suggests why conceptual design is so often neglected by development teams. Presents a five-step process for developing a sound conceptual model for a software application. Describes how technical communicators can reinforce and support conceptual design in their projects. (SR)

Beta testing--the process of trying a product in a real-world setting before releasing it commercially--exploits a natural interface between universities and high-technology industries. High-tech companies need confidential, real-world tests of new products, and universities are eager to get an early look at tomorrow's technology. (MLW)

Reviews principles for hardware selection, and forecasts the state of technology in terms of fidelity, feedback, and open architecture in language training. (six references) (GLR)

Item response theory (IRT) methodology is introduced as a tool for improving assessment instruments used with people who have disabilities. Need for this approach in rehabilitation is emphasized; differences between IRT and classical test theory are clarified. Concepts essential to understanding IRT are defined, necessary data assumptions are…

This section of the journal includes several short notes related to the teaching of science in secondary schools in Great Britain. Notes are included on ways of presenting science, rural science, designing experiments in chemistry, science for students with special needs, knowledge of the metric and imperial systems, and the use of spreadsheets.…

The author suggests that trainers charged with converting to computer-based training begin with a pilot program. He covers potential problems and how to address them. (CH)

Discusses the nature of programing languages, considering the features of BASIC, LOGO, PASCAL, COBOL, FORTH, APL, and LISP. Also discusses machine/assembly codes, the operation of a compiler, and trends in the evolution of programing languages (including interest in notational systems called object-oriented languages). (JN)

A computer operating system spans multiple layers of complexity, from commands entered at a keyboard to the details of electronic switching. In addition, the system is organized as a hierarchy of abstractions. Various parts of such a system and system dynamics (using the Unix operating system as an example) are described. (JN)

Discusses the development and nature of computer software for intelligent systems, indicating that the key to intelligent problem-solving lies in reducing the random search for solutions. Formal reasoning methods, expert systems, and sources of power in problem-solving are among the areas considered. Specific examples of such software are…

Explains the controversy surrounding the Office Assistant ("Paper-Clip") in Microsoft's Office 97. Discusses why actual readers rejected the default Office Assistant's role as implied writer and rebelled against the reader role implied for them. Notes users resented its intrusive behavior, rejected its implied writer role, and refused to…

The scaffolding metaphor was originally developed to describe the support given by a more expert individual in a one-on-one interaction. Since then, the notion of scaffolding has been applied more broadly, and it has been transformed and generalized. Most recently, it has been used by researchers in the learning sciences to describe features and…

The text of the EDUCOM statement on software and intellectual rights that educators are being urged to adopt on campus is presented and discussed. (MSE)
