Defines anonymous distributed computing systems and focuses on the specifics of a Java, applet-based approach for large-scale, anonymous, distributed computing on the Internet. Explains the possibility of a large number of computers participating in a single computation and describes a test of the functionality of the system. (Author/LRW)

This article discusses the process of integrating the use a software system into a conventional course in Abstract Algebra. It is a description of how and why a software system was used. It uses a particular system, Groups32, as an example.

This paper discusses a new form of specifying and normalizing a Linear Logistic Test Model (LLTM) as suggested by Bechger, Verstralen, and Verhelst ("Psychometrika," 2002). It is shown that there are infinitely many ways to specify the same normalization. Moreover, the relationship between some of their results and equivalent previous…

The Mechanical Equivalent of Heat Apparatus from PASCO scientific provides the means for doing a simple experiment to determine the mechanical equivalent of heat, "J." A necessary step of this experiment is to determine the temperature of an aluminum cylinder. By measuring the resistance of a thermistor embedded in the cylinder, one is able to…

The role of technology in education is ever increasing. This article looks at students with disabilities and the problem of writing independently. Speech recognition technology offers an option, or solution, for students who have physical and/or learning disabilities and for students who cannot access and use computer keyboards or switches.…

Standard least squares analysis of variance methods suffer from poor power under arbitrarily small departures from normality and fail to control the probability of a Type I error when standard assumptions are violated. This article describes a framework for robust estimation and testing that uses trimmed means with an approximate degrees of…

The efficiency of teaching algorithms can be highly improved by utilizing the senses as educational aids. The authors have developed a new didactical method and a software tool which exemplifies, for the case of simple algorithms, how the involvement of eyesight, hearing and the kinaesthesia can help in the teaching and learning process. This…

In this paper we present eTeacher, an intelligent agent that provides personalized assistance to e-learning students. eTeacher observes a student's behavior while he/she is taking online courses and automatically builds the student's profile. This profile comprises the student's learning style and information about the student's performance, such…

eXtensible Markup Language (XML) is a new technology that is currently being extolled by many industry experts and software vendors. Potentially it represents a platform independent language for sharing information over networks in a way that is much more seamless than with previous technologies. It is extensible in that XML serves as a "meta"…

An Excel add-in--XSEOS--that implements several excess Gibbs free energy models and equations of state has been developed for educational use. Several traditional and modern thermodynamic models are available in the package with a user-friendly interface. XSEOS has open code, is freely available, and should be useful for instructors and students…

The [Co(4-pyrimidinolate)[subscript 2](H[subscript 2]O)[subscript n]] species, which can be easily and selectively prepared by simple addition of aqueous solutions of the 4-pyrimidinolate organic ligand to Co(II) acetate (or nitrate) aqueous solutions (n = 4, 6) or by controlled heating of the hydrated phases (n = 0), proved to be versatile…

This article presents a list of this year's best practices from America's classrooms. This list was compiled by the staff of the Tech&Learning magazine. These best practices include: (1) video programs produced by the Horry County in Myrtle Beach, South Carolina; (2) a gaming design course introduced at Phoebus High School, Hampton City Schools,…

We appropriate Rogoff's ("Apprenticeship in thinking: Cognitive development in social context," 1991; in: Wertsch et al. (eds.) "Sociocultural studies of mind," 1993) notion of guided participation to demonstrate, through abbreviated case studies, our strategy for integrating mobile technology-based learning experiences in higher education. Guided…

While most high school juniors in Howard County, Maryland, were quietly studying in their classrooms, students enrolled in the Energy, Power and Transportation Academy (EPT) of the Applications and Research Lab (ARL), in Ellicott City, were making a lot of noise, welding and cutting away to build an all-terrain wheelchair. The author was a part of…

Cross-faculty and cross-disciplinary collaborations within higher education are rare, no doubt largely due to the location of academics within discipline- and faculty-based structures. When collaborations do occur, they are frequently problematic, even when the collaborators stem from closely related disciplines. However, collaborations are…
