Proposes a model for constrained computerized adaptive testing in which the information in the test at the trait level (theta) estimate is maximized subject to the number of possible constraints on the content of the test. Test assembly relies on a linear-programming approach. Illustrates the approach through simulation with items from the Law…

Illustrates public television's early commitment to children's programming, discussing the popularity of "Sesame Street" and noting other shows launched under Joan Ganz Cooney, president of CTW from 1970 until 1988. Discusses the erosion of television network ratings by cable television in the mid '80s, and concludes by posing questions…

Unlike most program assessment systems, Program Assessment using Specified Solutions (PASS), evaluates student C programs by assessing the way a problem was solved by performing a comparison of the submitted program with a solution plan. This article describes PASS, its use of instructor specified solution plans, assessment and feedback systems,…

Describes XML (extensible markup language), a new language classification submitted to the World Wide Web Consortium that is defined in terms of both SGML (Standard Generalized Markup Language) and HTML (Hypertext Markup Language), specifically designed for the Internet. Limitations of PDF (Portable Document Format) files for electronic journals…

Examines GTE (Generic Tutoring Environment) from an authoring perspective, describes how GTE may be used to create courseware, and reviews potential difficulties that authors face when using such a tool. Summarizes two studies that investigated how authors used GTE and concludes that GTE designs are difficult for authors to test and evaluate.…

Analysis of 23,704 want ads for computer-related jobs revealed that the most frequently mentioned skills were UNIX, SQL programming, and computer security. Curriculum implications were derived from the most desired and less frequently mentioned skills. (SK)

Describes expert systems and discusses their use in libraries. Highlights include parts of an expert system; expert system shells; an example of how to build an expert system; a bibliography of 34 sources of information on expert systems in libraries; and a list of 10 expert system shells used in libraries. (Contains five references.) (LRW)

Describes a visual tutoring system for programming distributive-memory multiprocessor networks. Highlights include difficulties of parallel programming, and three instructional modes in the system, including a hypertext-like lecture, a question-answer mode, and an expert aid mode. (Author/LRW)

This primer on authoring tools for training provides tips on selecting software, questions to assess whether to use it, and a directory of companies selling multimedia authoring products. (SK)

Constructs a recursion programming learning system based on Socratic dialog which presents questions to students and encourages them to reflect on their own thinking. Highlights include implementation using database techniques; evaluation by empirical methods; and results of pretests and posttests that show a positive impact on recursion…

The notions of pentagonal numbers and partitions can be understood by students at the precalculus level, and should work well in a first course in programming for high school or college students. Presents opportunities to conjecture properties of partitions from a computer program. (Contains 14 references.) (Author/ASK)

Examines violence in music video programming. Reveals that 15% of music videos feature violence, and most of that aggression is sanitized, not chastised, and presented in realistic contexts. Discusses the findings in terms of the risk that exposure to violence in each channel and genre may be posing to viewers' learning of aggression, fear, and…

Assesses the prevalence and context of violence in prime-time television programming using a random, representative sample. Shows that, regardless of the time of day, viewers are likely to encounter violence in roughly 2 out of 3 programs. Identifies specific channel types and genres that feature potentially harmful depictions of violence during…

Assessed children of three age groups (4-5, 6-7, and 8-10) on reality/fantasy distinction and story-schema development after viewing episode of "Mighty Morphin' Power Rangers." Found that only oldest children could make clear distinction between reality and fantasy, and that older children showed mastery of other study variables: memory…

Notes the correlation between television-viewing habits and children's level of creativity, aggressiveness, and social skills. Highlights better quality programming, noting that most of it is on cable rather than network television. Cautions against the less controllable factors such as commercials and "teasers" for other programs and movies. (HTH)
