An experiment is proposed for learning the principles of radio. A simple radio receiver illustrates amplitude modulation and demodulation, the selectivity of a receiver and the features of a directional antenna. Both normal and computerized versions of the experiment are described. The computerized experiment employs the "ScienceWorkshop"…

The teaching of energy throws up many different approaches and causes many arguments. This paper describes yet another approach to teaching the subject matter using a system of diagrams, but hopefully one that will be an acceptable compromise for many teachers. Lord Rutherford is often quoted as saying, "All science is either physics or stamp…

PowerPoint has become something of a standard business communication tool, for better or worse. The "worse" part of that formulation is something of a cliche in the business world, and poor use of the tool can be damaging to a business manager's career progress. The author has been using a two-part approach to teaching PowerPoint skills in an…

This article features the latest classroom technologies namely the FLY Pentop, WriteToLearn, and a new iris scan identification system. The FLY Pentop is a computerized pen from Leapster that "magically" understands what kids write and draw on special FLY paper. WriteToLearn is an automatic grading software from Pearson Knowledge Technologies and…

At the start of a freshman calculus course, many students conceive the classical definition of limit as the most problematic part of calculus. They not only find it difficult to understand, but also consider it of no use while solving most of the limit problems and therefore, skip it. This paper reformulates the rigorous definition of limit, which…

The application of technology to educational settings has always been an interesting phenomenon. Each new technological advance is described as a panacea for whatever ails education at that moment. As people move closer to more current times, the influence of personal computers and the rise of the internet has affected the educational setting in…

One of the simulation engines of an open-source program called the Molecular Workbench, which can simulate thermodynamics of chemical reactions, is described. This type of real-time, interactive simulation and visualization of chemical reactions at the atomic scale could help students understand the connections between chemical reaction equations…

UCLA, which has one of the top 10 research libraries in the country, has been using Taos software since 1996. However in 2001, Sirsi Corp. announced that it was freezing development on Taos software. As the associate university librarian for information technology at UCLA, the author relates that it was his responsibility to lead the way through…

This article presents an interview with Jim Hirsch, an associate superintendent for technology at Plano Independent School District in Plano, Texas. Hirsch serves as a liaison for the open technologies committee of the Consortium for School Networking. In this interview, he shares his opinion on the significance of open source in K-12.

Articles in this issue of "Global Journal of Computer Science and Technology" include: (1) Input Data Processing Techniques in Intrusion Detection Systems--Short Review (Suhair H. Amer and John A. Hamilton, Jr.); (2) Semantic Annotation of Stock Photography for CBIR Using MPEG-7 standards (R. Balasubramani and V. Kannan); (3) An Experimental Study…

The Horizon Report series is the product of the New Media Consortium's Horizon Project, an ongoing research project that seeks to identify and describe emerging technologies likely to have a large impact on teaching, learning, research, or creative expression within education around the globe. This volume, the "Horizon Report: 2009 K-12…

To ensure their teaching quality, it is important for student teachers to undertake self reflection on their teaching performance after supervised teaching sessions. With the goal of sharpening the teaching competence of student teachers, a dual function system that uses web based and video based technologies is being developed to facilitate self…

Purpose: The benefits of an educational shift to graduate attribute development have been foregrounded in the educational literature since the early 1990s. Attribute mapping in documentation with no change to assessment constitutes a surface approach. This paper aims to use as an example a deep approach that uses software to facilitate staff and…

Within large scale educational assessment agencies in the UK, there has been a shift towards assessors marking digitally scanned copies rather than the original paper scripts that were traditionally used. This project uses extended essay examination scripts to consider whether the mode in which an essay is read potentially influences the…

"VideoPaper Builder" (VPB) was originally funded in 2001 through the National Science Foundation's "Bridging Research and Practice" program in recognition of the software's promise to articulate the relevance and facilitate the dissemination of educational research to practicing teachers. After four years and two subsequent…
