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.

Purpose: To review the variety of software solutions available for putting CDS/ISIS databases on the internet. To help anyone considering which route to take. Design/methodology/approach: Briefly describes the characteristics, history, origin and availability of each package. Identifies the type of skills required to implement the package and the…

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…

This report provides national data on the availability and use of educational technology among teachers in public elementary and secondary schools during the winter and spring of 2009.
