"Microwave Workshop for Windows" consists of three programs that act as teaching aid and provide a circuit design utility within the field of microwave engineering. The first program is a computer representation of a graphical design tool; the second is an accurate visual and analytical representation of a microwave test bench; the third…

Describes the commercial pressures faced by public service educational television and results of poor public sector funding for core educational establishments. Discusses new technologies and financial deprivation; new partnerships and players; and the role for public broadcasters. (AEF)

Presents a multimedia component kit for digital electronics authoring and learning. Components available on the Internet facilitate sharing and reuse of educational software and provide authoring support. Emphasis is put on the implementation of a number of components based on simulation and animation that provide a high level of interactivity and…

PLUS, an authoring system designed to develop cross-platform courseware for different computer types, was evaluated for its portability (ability to run on multiple platforms without adjustment). The procedures and computer equipment used are described, and results are presented. It is concluded that PLUS produces highly portable programs. (MSE)

A firm that has designed many preschool and elementary school projects identifies three factors that are vital to successful design for young children: protection, interaction, and scale. Accompanying drawings of three projects illustrate these design principles. (MLF)

R is free, open-source, cooperatively developed software that implements the S statistical programming language and computing environment. The current capabilities of R are extensive, and it is in wide use, especially among statisticians. The sem package provides basic structural equation modeling facilities in R, including the ability to fit…

Students in an introductory computing class participated in a study investigating the impact of using a graphics programming environment (Alice) and pair-programming on confidence, enjoyment and achievement. Sixty-four participants completed a short questionnaire and a content pre-test about computer programming concepts. Students were then…

Culture offers people suggestions for dealing with life's vicissitudes, and people find different suggestions in different cultures. In a multicultural society, they have a variety of alternatives to choose among: ethnicities, regionalisms, lifestyles, religious movements, occupations, hobbies, and more. In American society, the groups that are…

Recursion is a central concept in computer science, yet it is difficult for beginners to comprehend. Israeli high-school students learn recursion in the framework of a special modular program in computer science (Gal-Ezer & Harel, 1999). Some of them are introduced to the concept of recursion in two different paradigms: the procedural…

This paper reports on a design experiment in the domain of number sequences conducted in the course of the "WebLabs" project. We iteratively designed and tested a set of activities and tools in which 10-14 year old students used the "ToonTalk" programming environment to construct models of sequences and series, and then shared…

This paper examines the problem of studying and comparing student software designs. We propose semantic categorization as a way to organize widely varying data items. We describe how this was used to organize a particular multi-national, multi-institutional dataset, and present the results of this analysis: most students are unable to effectively…

In this paper, the current profile of the environmental engineer and the programming of the subject "Environmental Engineering and Technology" corresponding to the studies of Mining Engineering at the University of Oviedo in Spain, is discussed. Professional profile, student knowledge prior to and following instruction as well as…

This paper examines the contention that learning environments which use IMS Learning Designs can be created by plugging in different components, using generic service descriptions to create the interface between the Learning Design (LD) and the specific tools. There is an alternative viewpoint which claims that generic service descriptions cannot…

In this article, the author proves a theorem about polynomial zeros, but the focus is on how the theorem is integrated into a QuickBASIC computer program, and how that program answers the questions of the theorem--a unification of mathematics and computer programming. For a given polynomial, how can one overcome assorted problems in finding zeros…

I Sing the Body Electric (BODY ELECTRIC) is a fine arts and health promotion program that supports communication of healthy lifestyle choices among youth. BODY ELECTRIC connects youth in 27 high schools with health and education communities in the largest rural geographic education region in a Midwestern state. The three-phase prevention plan…
