This article presents the features, design and architecture of the Myst pervasive game platform that has been applied in creating pervasive mobile learning games in various contexts such as science festivals and museums in Finland. Based on our experiences with the development, we draw a set of design principles for creating successfully a…

Writing programs and more specifically, Writing in the Disciplines (WID) initiatives have begun to embrace the use of and the ideology inherent to, open source software. The Conference on College Composition and Communication has passed a resolution stating that whenever feasible educators and their institutions consider open source applications.…

Collective communication allows efficient communication and synchronization among a collection of processes, unlike point-to-point communication that only involves a pair of communicating processes. Achieving high performance for both kernels and full-scale applications running on a distributed memory system requires an efficient implementation of…

"Reflective Database Access Control" (RDBAC) is a model in which a database privilege is expressed as a database query itself, rather than as a static privilege contained in an access control list. RDBAC aids the management of database access controls by improving the expressiveness of policies. However, such policies introduce new interactions…

This dissertation presents evidence that the production of Free and Open Source Software (FLOSS) is far more alone than together; it is far more often individual work done "in company" than it is teamwork. When tasks appear too large for an individual they are more likely to be deferred until they are easier rather than be undertaken through…

The enterprise software market is seeing the rise of a new business model--selling Software-as-a-Service (SaaS), in which a standard piece of software is owned and managed remotely by the vendor and delivered as a service over the Internet. Despite the hype, questions remain regarding the rise of this new service model and how it would impact the…

This study investigated the various teaching strategies implemented by the teachers in a computer-based Mathematics course delivery model created by the LSU Math Department and applied in Louisiana High Schools. This model was referred to as R2R (Roadmap to Redesign). It was a course design that includes whole class instruction time (about 25% of…

As budget cuts loom in school districts across the nation, school librarians are expected to show artifacts and share data to cement their credibility as instructional leaders, since according to Zmuda (2007) and many others, the effectiveness of the school library media program must be measured by what students learn as a result of their…

In this article, the author discusses using Second Life (SL) in school librarianship. SL is a multi-user virtual environment in which persons create avatars to allow them to move and interact with other avatars. They can build and manipulate objects. To move, they can walk, run, fly, or teleport. There are many areas within SL to allow people to…

A large school district may have a technology department staffed by a chief technology officer who supervises two or more directors of operations, project managers, and technicians. On the other hand, a small district may employ an information technologist who works with technicians, consultants, volunteers with a knack for technology, and…

Plagiarism sometimes creates legal and ethical problems for students and faculty. It can have serious consequences. Fortunately, there are ways to stop plagiarism. There are many tools available to detect plagiarism, e.g. using software for detecting submitted articles. Also, there are many ways to punish a plagiarist, e.g. banning plagiarists…

This paper describes materials designed for classroom projects on stimulus generalization and peak shift. A computer program (originally written in QuickBASIC) is used for data collection and a Microsoft Excel file with macros organizes the raw data on a spreadsheet and creates generalization gradients. The program is designed for use with human…

This paper describes the use of open source video analysis software in the study of the relationship between the velocity of falling objects and time. We discuss an experiment in which a steel sphere falls in a container filled with two immiscible liquids. The motion is similar to that of a skydiver falling through air.

To date, over one-fifth of all U.S. higher education students are now taking at least one online course. The Sloan Consortium (Sloan-C) recently surveyed more than 2,500 colleges and universities to reveal that over 3.9 million students were taking at least one online course during the 2007 fall term. This number is a 12% increase from fall 2006.…

Goran Radman (GR) joined Microsoft in 1996 and served until Fall 2008 as Microsoft Chairman, Southeast Europe (SEE) and Chairman, East and Central Europe (ECEE). Based in Croatia, where he enjoys sailing the Adriatic coast and islands, he spoke with the authors during 2008 and 2009 about his experience launching Microsoft's commercial presence in…
