Relationships between Bayesian ability estimates and the parameters of a normal population distribution are derived in the context of classical test theory. Analogies are provided for use as approximations in work with item response theory (IRT). The following issues are addressed: (1) the relationship between the distribution of the latent…

To use computers as a medium to learn a language, there is need for some GUI-elements indicating and regulating the actual status of training. These elements have to be separated into obligatory ones, useful in almost all CALL-software, and facultative ones, necessary for most "teachware." Due to a general need of reducing the difficulties to get…

Anthropomorphism can be defined as the attribution of human characteristics or behavior to inanimate objects. People give names to their automobiles and computers as a way to relate to complicated pieces of technology that they use regularly, but do not fully understand. Software designers may claim that their interfaces are intuitive, but in…

Because of the graphical interface and "openness" of the operating system, Macintosh computers are susceptible to undesirable changes by the user. This presentation discusses the advantages and disadvantages of software packages that offer protection for the Macintosh system. The two basic forms of software security packages include a…

This newsletter presents an introduction to the Internet. A definition of the Internet and its three principle uses--electronic mail, USENET newsgroups, and information files--are provided. A discussion on how to explore the Internet includes equipment needs, university Internet accounts, commercial vendors, navigating the Internet through the…

This book provides descriptions of approximately 270 CD-ROM packages and series, and references to dozens of others, all which are especially suitable for libraries. Organized by subject, entries include the vendor price (when available), platform and hardware requirements, and availability of network versions. In addition, evaluative comments…

This paper reviews two of the United Kingdom's national programs to promote the use of computer-based teaching throughout higher education. In the first phase (1985-89) of the Computers in Teaching Initiative (CTI), a suite of 139 individual software-production projects generally failed to meet expectations. In 1989, CTI became a network of…

The availability of digital multimedia technology poses new challenges to researchers, authors, and educators, even as it creates new opportunities for communication. VideoScheme, a prototype video programming environment is described, along with its applications in research, authoring and education. In terms of research, VideoScheme can help…

As an instructional technology, cognitive apprenticeship has become increasingly important. Cognitive apprenticeship embeds the acquisition of knowledge and skills in their social and functional context and consists of six teaching methods: modelling, coaching, scaffolding, articulation, reflection, and exploration. SMALLTALKER is a…

Patron service is a high priority in the library setting and alleviating a large percentage of the directional questions will provide librarians with more time to help patrons more thoroughly than they are able to currently. Furthermore, in view of the current economic trend of downsizing, a navigational computer system program has the potential…

The history of instructional multimedia systems development includes many difficulties--authorial uncertainty about how to order concepts, the misplaced focus of so-called "intelligent tutors," the sometimes disconcerting proliferation of products, and financial constraints. Against this background, this paper discusses the project which…

This paper evaluates four tools for creating World Wide Web pages that interface with Microsoft Access databases: DB Gateway, Internet Database Assistant (IDBA), Microsoft Internet Database Connector (IDC), and Cold Fusion. The system requirements and features of each tool are discussed. A sample application, "The Virtual Help Desk"…

This guide highlights the basic operation of software that provides a framework and tools for students to encounter computer-based multimedia reviews of the books the have read independently given minimal equipment and expertise, and suggests ways to go beyond the basic operation for those who have the capability to do so. After a background and…

Many reference librarians still rely on manual searches to access vertical files, ready reference files, and other information stored in card files, drawers, and notebooks scattered around the reference department. Automated access to these materials via microcomputers using database management software may speed up the process. This study focuses…
