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 objectives of training activities as stated in the DoW are: 1. to organize training within the project for the participants to learn to use the necessary tools; 2. to support training activities of the partners when they deliver and take in use the tools and practices during extended pilots. The approach with regards to the first point is that…

This paper introduces several hands-on projects that have been used to motivate students in learning various computer networking concepts. These projects are shown to be very useful and applicable to the learners' daily tasks and activities such as emailing, Web browsing, and online shopping and banking, and lead to an unexpected byproduct,…

Collaborations between business and academia provide valuable opportunities for students to connect classroom learning with practical work experience. To effectively reach a significant number of students, one approach is to meld a real-world business project and classroom assignment into a realistic business scenario that can be addressed by…

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.…

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…

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)

Maintains that one recurring theme in the Text Encoding Initiative (TEI) project has been the need to represent nonhierarchical information in a natural way. Proposes solutions to a variety of related problems. Contends that the examples presented can serve as a useful background for researchers using the TEI guidelines. (CFR)

Describes tools for authoring all aspects of a knowledge-based tutor system: domain model, teaching strategies, student model, and learning environment. Discusses a number of design issues and design tradeoffs that are involved in building intelligent tutoring systems (ITS). (Author/CCM)

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…
