Examines the self-directed activity of two students who learned about molecular structure by writing computer programs. The programs displayed the solution of a mathematics problem, then the programs were extended to represent several classes of organic molecules. Different ways to enhance mathematical connections to chemistry education are…

Discusses how the World-Wide Web (WWW) can be linked to the PAT system, a search engine supporting access to Standard Generalized Markup Language (SGML) encoded documents. Technical concepts are reviewed, and the operation of a PAT-to-Web gateway is explained using examples of how it is employed. (JKP)

Presents a description of Fabula software, which enables children learning European minority languages to create bilingual digital books. Discusses the ways in which it has been used in schools in Europe, and highlights future plans, including a Europe-wide competition for schools and the creation of a WWW-based on-line library for teachers and…

Computer operations involving complex numbers, essential in such applications as Fourier transforms or image processing, are normally performed in a "divide-and-conquer" approach dealing separately with real and imaginary parts. A number of proposals have treated complex numbers as a single unit but all have foundered on the problem of the…

The pervasive popularity of the Internet in the past decade has changed the way many students live and learn, in part, because modern technology has made it possible for learners to access Real-Time Multimedia information on the Internet, or research any topic of interest to them from virtually any computer anywhere in the world. Students can also…

This article presents a novel approach for explaining algorithms that aims to overcome various pedagogical limitations of the current visualization systems. The main idea is that at any given time, a learner is able to focus on a single problem. This problem can be explained, studied, understood, and tested, before the learner moves on to study…

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…

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 article, the authors explain how they implemented Design eXchange as a shared collaborative online and physical space for design for their students. Their notion for Design eXchange favors a complex mix of key elements namely: (1) a virtual online studio; (2) a forum for review of all things related to design, especially design with the…

School districts prepare annual budgets in order to have adequate funding available for their operations. Today's budgets require flexibility and adaptability as school-district finances and governmental regulations and guidelines change. This article discusses several types of budgets and budget preparation that utilize microcomputer technology.…

The University of Miami recently reclassified their "State of Florida" documents according to the classification system invented by Florida Atlantic University (FAU) in 1966. Using only in-house resources, the Government Documents Department of the University of Miami generated labels with printed call numbers for over 16,000 documents.…

Papers from the meeting on computational linguistics include: "Conversational Games, Belief Revision and Bayesian Networks" (Stephen G. Pulman); "Valence Alternation without Lexical Rules" (Gosse Bouma); "Filtering Left Dislocation Chains in Parsing Categorical Grammar" (Crit Cremers, Maarten Hijzelendoorn);…

This article provides a rationale for educators to use multimedia computer technologies to create individualized computer-based instructional materials for students with autism. Software design guidelines based on empirical research are presented, along with detailed descriptions of two multimedia authoring systems for educators. Suggestions focus…

Describes the Text Encoding Initiative (TEI) guidelines' approach to describing hypertext features. Discusses the rationale behind the design of the tagset and the range of features included in the guidelines. Discusses the relation and integration of TEI mark-up and the HyTime standard. (CFR)
