Rough set theory (RST) is an emerging technique used to deal with problems in data mining and knowledge acquisition. However, the RST approach has not been widely explored in the field of academic achievement. This investigation developed an improved RST (IMRST) model, which employs linear discriminant analysis to determine a reduct of RST, and…

Accessing to information technology and the ability to use it is increasingly becoming part of the toolkit necessary to participate and prosper in an information-based society. Inequalities in ICT access and use not only mirror existing patterns of social stratification, but can also maintain and even widen current disparities between these groups…

YouTube is an Internet phenomenon, a video sharing Web site where individuals can upload videos to be viewed by anyone visiting the site. The purpose of this study was to search for and categorize videos related to disability on YouTube and explore the educational potential of the site for the disability community. A seven-day time period in…

Online social networking is more than just a passing fad; it's a phenomenon that unifies people of all ages across the Internet and around the world. The most popular social networking sites are Facebook and MySpace--both founded in the United States. However, the United States does not have a corner on the market. Hi-5 is rooted in Asia, Skyrock…

Digital lecturing systems (computer and projector, often with PowerPoint) offer physics instructors the ability to incorporate graphics and the power to share and reuse materials. But these systems do a poor job of supporting interaction in the classroom. For instance, with digital presentation systems, instructors have limited ability to…

Technology has changed people's lives. In fewer than 30 years, people have gone from barely hearing about cell phones, laptops, and MP3 players to almost not being able to live without them. Digital citizenship describes the norms of appropriate, responsible behavior with regard to technology use. In this article, the author presents nine elements…

Evolve or dissolve. That advice, from a recent report on virtual universities, played out in two news stories last May 2009. The University of Texas' online division is staring down a deep budget hole as it loses a longtime subsidy. In Utah, budget cuts have killed a 10-campus online consortium. Those and other predicaments reflect the growing…

Modern approaches for technology-based blended education utilize a variety of recently developed novel pedagogical, computational and network resources. Such attempts employ technology to deliver integrated, dynamically-linked, interactive-content and heterogeneous learning environments, which may improve student comprehension and information…

Shared vision is a component of leadership that fosters innovation through buy-in at all levels of the organization. At times, people see a need for innovation but do not have the power to make changes on their own. Many librarians in academic institutions that were early adopters of distance learning envisioned a need for new services that were…

Newsletters, websites, local access television and community newspapers serve as the typical media superintendents use to get the word out to parents and public. One might logically ask, "Isn't that enough to deal with?" School superintendents with so much to communicate need to move beyond a reliance on the traditional media outlets. These no…

What makes games effective for learning? The authors argue that games provide vicarious experiences for players, which then amplify the effects of future, formal learning. However, not every game succeeds in doing so! Understanding why some games succeed and others fail at this task means investigating both a given game's design and the…

The application of technology in classroom settings has equipped educators with innovative tools and techniques for effective teaching practice. Integrating digital technologies at the elementary and secondary levels helps to enrich the students' learning experience and maximize competency in the areas of science, technology, engineering, and…

What if your professional learning community was available 24 hours a day, every day of the year? Would you like to have a place to share lesson plans, student work, a new curriculum, and to provide a discussion forum for all stakeholders? You can, even with only a basic understanding of technology. The authors explain how they created an online…

In 2006, the North American Council for Online Learning (NACOL) conducted its first international survey, researching how other countries were implementing online and blended learning opportunities for their primary and secondary (K-12) students. As the pace of growth of online and blended learning has grown at an average of over 30% each year for…

Online K-12 education made its appearance in the mid-1990s, largely as a resource for bright students who had no access to accelerated classes. It moved next into core high-school courses where districts found themselves with teacher shortages--math, science, foreign languages--and has been growing bumptiously, and in a dozen directions, ever…
