Written from the viewpoint of an observer of the computer industry and a CD-ROM user, this report looks at CD-ROM evaluation guidelines; notes the performance of publishers; and comments on successful product design. It is contended that some software publishers are jumping on the CD-ROM bandwagon, and are guilty of: (1) putting "any old stuff"…

This paper describes how a new "Moodle" module, called "CTPracticals", is applied to the teaching of the practical content of a basic computer organization course. In the core of the module, an automatic verification engine enables it to process the VHDL designs automatically as they are submitted. Moreover, a straightforward…

RESGEN is a computer program designed to generate simulated latent trait distributions and then dichotomous or polytomous item responses based on item response models. The latent trait distributions can be univariate or multivariate normal, log-normal, uniform, or gamma. The item response models utilized in this program may have characteristics…

Classifies types of electronic books: archival, informational, instructional, and interrogational; evaluates five commercially, available examples and two in-house examples; and describes software tools for creating and delivering electronic books. Identifies crucial design considerations: interactive end-user interfaces; use of hypermedia;…

Describes "Let's Write!" a writing package for the MS-DOS network which combines five software programs to define a new collaborative dynamic for writing, reading, and thinking on computer networks. (SR)

Description of the automation of the technical library of the City of Los Angeles Department of Information Services provides background information on the department and its library; lists the automation project goals and objectives; and describes the two software programs--ObjectVision and Paradox Engine--used as applications development tools…

High-profile criminal acts continue to plague United States (US) college campuses despite recent efforts to implement more aggressive risk mitigation practices, such as criminal background checks. Despite these efforts, incidents such as the most recent shootings at Virginia Polytechnic Institute and State University continue to demonstrate that,…

When the author first used "VisiCalc," the author thought it a very useful tool when he had the formulas. But how could he design a spreadsheet if there was no known formula for the quantities he was trying to predict? A few months later, the author relates he learned to use multiple linear regression software and suddenly it all clicked into…

The debate about the impact of information and communication technology has tended to focus on either its economic or its political aspects. The growing centrality of this technology to life in the 21st century, however, raises important questions about social ownership and control that necessitate a broader and more holistic analysis. Central to…

A single equation of state (EOS) such as the Peng-Robinson EOS can accurately describe both the liquid and vapor phase. We present several applications of this equation of state including adiabatic flash calculation, determination of the solubility of methanol in natural gas, and the calculation of high-pressure chemical equilibrium. The problems…

What makes Dynamic Geometry Environment (DGE) a powerful mathematical knowledge acquisition microworld is its ability to visually make explicit the implicit dynamism of thinking about mathematical geometrical concepts. One of DGE's powers is to equip us with the ability to retain the background of a geometrical configuration while we can…

We describe exercises in which students use PascGaloisJE to formulate conjectures about certain binomial identities which hold when the binomial coefficients are interpreted as elements in the cyclic group Z[subscript p] of integers modulo a prime integer "p". In addition to having an appealing visual component, these exercises are open-ended and…

Algebra is one of those hard-to-teach topics where pupils seem to struggle to see it as more than a set of rules to learn, but this author recently used the software "Grid Algebra" from ATM, which engaged her Year 7 pupils in exploring algebraic concepts for themselves. "Grid Algebra" allows pupils to experience number,…

The Varignon parallelogram has always provided a simple geometric investigation for students that gives rise to a surprising result. It is possible to extend the Varignon investigation by looking at special quadrilaterals or by considering different dissection points along the sides. In the second of his two-part series, the author offers some…

A widget displays Web content from external sources and can be embedded into a blog, social network, or other Web page, or downloaded to one's desktop. With widgets--sometimes referred to as gadgets--one can insert video into a blog post, display slideshows on MySpace, get the weather delivered to his mobile device, drag-and-drop his Netflix queue…
