This paper proposed the question "How do we teach logical thinking and sophisticated mathematics to unsophisticated college students?" One answer among many is through the writing of computer programs. The writing of computer algorithms is mathematical problem solving and logic in disguise and it may attract students who would otherwise stop…

A method based on 0-1 linear programming (LP) is presented to stratify an item pool optimally for use in "alpha"-stratified adaptive testing. Because the 0-1 LP model belongs to the subclass of models with a network-flow structure, efficient solutions are possible. The method is applied to a previous item pool from the computerized…

Provides an overall view of the present state of educational broadcasting in Greece, discusses the main reasons that hinder its development, and proposes solutions for improvement. Government control and the direct imitation of foreign broadcasting programming are cited as two main problems that need to be overcome. (Author/LRW)

Looks at the ways in which the relationship between women and work was characterized during the late 1940s in "Woman Speaks," a combination newsreel/television show in Chicago. Expands upon the work of other historians and critics who have examined the representations of gender in early television marketing ploys and variety/situation…

ISO--International Organization for Standards highlights the activities of WG8 (Working Group 8 of ISO) in the alignment of standards for a common tree model and common query languages. Examines the how Document Style Semantics and Specification Language (DSSSL) and HyTime make documents easier to work with and more powerful in their ability to…

Reports on a computer application in which collaboration did not precede project design. Important project parameters established without author input presented ethical dilemmas in balancing contract obligations and methodological rigor. (Author/CK)

Proposes a model for digital library and hypermedia organizations that is adaptive, providing different conceptual orderings to support browsing for different individuals' or groups' needs. Highlights include types of links, document ordering and the Gray code (a binary programming code), adaptive classification, and an economic model for document…

Examines the complex nature of pretense as portrayed in a popular UK children's television puppet show. Argues that animality of puppets is rendered opaque as their identities as children are linguistically accomplished, leading to a piece of representational art structured by moral and behavioral dictates typical of conventional adult-child…

Presents a Web portal for multicast communication management, which provides fully automatic service management with integrated provisioning of hardware equipment. Describes the software architecture, the implementation, and the application usage of the Web portal for multicast delivery. (Author/AEF)

Examines the popular portrayal of intellectual expertise through a content analysis of 200 of the 10 top-rated popular US television talk shows. Shows that experts in this sample were typically brought on late in the program, allotted little speaking time, placed among non-experts, frequently interrupted, and sometimes challenged. Indicates that…

Discusses how to improve the quality of Internet search systems and introduces the Ghosts Consensus Method which is free from the drawbacks of digital democracy algorithms and is based on linear programming tasks. Highlights include vector space models; determining relevant documents; and enriching query terms. (LRW)

Reports descriptive analyses of production data gathered from experienced instructional developers who used a commercial authoring package and supplemental coding over a one-year period to produce three separate instructional lessons on thinking skills as part of a larger commercial educational product. (Author/LRW)

Describes a lesson designed to teach a computer programming construct, the "if-then" statement, and to help students gain insight into computing concepts, stimulate students' creativity, and develop their higher order thinking skills. (JKP)

Investigates the management of expertise in advice-giving in the calls to a radio advice line. Analyzes how the expert's talk handles the tension between the personal and public dimensions of advice-giving in such a public forum. (HB)
