The capability of the DIMTEST statistical test in assessing essential unidimensionality of item responses to real tests was investigated for 22 real tests of at least 25 items and 700 or more examinees. DIMTEST results on real tests were able to discriminate between essentially unidimensional and multidimensional tests. (SLD)

Introduces a new way of looking at concepts called Hazyspace that focuses on the messiness of real life and the indeterminancy of concepts as key features in understanding the conceptual domain of human beings. Although Hazyspace has general applicability to education, this discussion focuses on use of the term to describe how new users…

Affluent and disadvantaged children stand in lunch lines and dine in school cafeterias as equals at the Bay Shore Schools (NY). Thanks to a computerized "LunchBox" point-of-sale system, cashiers know children by name, their birthdays, who suffers from which food allergies, and which children are entitled to free or reduced-price meals.…

An analysis of sibling data from the National Youth Survey shows the pitfalls of ignoring issues of independence and demonstrate how conventional covariance structure software can be easily adapted to handle hierarchical models, providing a new approach that models within-level and between-level covariance matrices in familial antisocial behavior.…

Discusses technology-enhanced language learning (TELL) in the United Kingdom developed under the Teaching and Learning Technology Programme (TLTP) and the Computers in Teaching Initiatives (CTI) Centre for Modern Languages. The use of technology for computer-assisted language learning, the integration of technology, and courseware development are…

Presents basic considerations when school districts plan to acquire an access-control system for their education facilities. Topics cover cards and readers, controllers, software, automation, card technology, expandability, price, specification of needs beyond the canned specifications already supplied, and proper usage training to cardholders.…

Describes a method for evaluating results of Procrustean rotation to a target factor pattern matrix in exploratory factor analysis. The approach, based on the bootstrap method, yields empirical approximations of the sampling distributions of: (1) differences between target elements and rotated factor pattern matrices; and (2) the overall…

Surveyed 364 members of the Society for Personality Assessment to determine how they use computer-based test interpretation software (CBTI) in their work, and their perspectives on the ethics of using CBTI. Psychologists commonly use CBTI for test scoring, but not to formulate a case or as an alternative to a written report. (SLD)

Presents WebShaman, an application built to demonstrate how a distributed virtual prototyping system with a client/server architecture, could support geographically distant designer/customer communication. Provides an overview of smart virtual prototyping; discusses implementation of synchronous collaboration via the World Wide Web; and assesses…

To help users develop a long-term strategy for software acquisition, this article outlines two rules: (1) "Know exactly the nature of the problem you want to solve"; and (2) "If you can't try it, don't buy it." Use the sharpest precision software tool you can find to solve your problem and keep a constant look out for something…

Examines roles technical communicators play in designing and developing information systems, especially online help. Surveys technical communicators, developers, and users. Finds users of systems for which the online help was written by a technical communicator used the online help more often and rated the quality of that help higher. Discusses…

This special section includes "The View from the Middle" (Dick Schaaf); "Crossing the Channel" (Dawn Garrett); and "Bandwidth Basics" (Dick Schaaf). Sidebars look at bandwidth and management issues as well as courseware development. (JOW)

Discusses situations that are ready for the formation of a learning community and suggests that virtual learning might be the answer. Offers a case study of a software-development company and explains how to set up elements on an intranet. Includes marketing tips for promoting the new learning community. (JOW)

Describes a method of designing educational technology that is strongly informed by empirical studies of how students actually understand and use technology. Discusses what students need to know about software. (Author/CCM)
