Forms of expression and representation other than writing have unquestionably been revolutionised by developments in new technology and computer software. Digital photography has made it possible to alter and enhance the original image in an almost infinite number of ways. Music software programmes like Cubase and Sibelius make it possible to…

Many phenomena generate interesting audible time series. This data can be collected and processed using audio software. The free software package "Audacity" is used to demonstrate the process by recording, processing, and extracting click times from an inexpensive radiation detector. The high quality of the data is demonstrated with a simple…

Hiring substitute teachers used to be an early-morning calling burden for staff members at schools in Oregon's Coos Bay School District. Now that work has been passed off to Aesop, a service from Frontline Placement Technologies, which springs into action upon receiving a notification, either by call or log-in, from a teacher reporting an absence.…

Recent advances in technology have made video capture and analysis in the introductory physics lab even more affordable and accessible. The purchase of a relatively inexpensive web camera is all you need if you already have a newer computer and Vernier's Logger Pro 3 software. In addition to Logger Pro 3, other video analysis tools such as…

After years at the periphery of the social sciences, simulation is now emerging as an important and widely used tool for understanding social phenomena. Through simulation, researchers can identify causal effects, specify critical parameter estimates, and clarify the state of the art with respect to what is understood about how processes evolve…

Large-scale projects such as the Internet Archive (www.archive.org) send out crawlers to gather snapshots of much of the web. This massive collection of archived websites may include content of interest to one's patrons. But if librarians want to control exactly when and what is archived, relying on someone else to do the archiving is not ideal.…

From Web guides to online tutorials, academic librarians are increasingly experimenting with many different technologies in order to meet the needs of today's growing distance education populations. In this article, the author discusses one librarian's experience using Camtasia Studio to create subject specific video tutorials. Benefits, as well…

Bayesian multidimensional scaling (MDS) has attracted a great deal of attention because: (1) it provides a better fit than do classical MDS and ALSCAL; (2) it provides estimation errors of the distances; and (3) the Bayesian dimension selection criterion, MDSIC, provides a direct indication of optimal dimensionality. However, Bayesian MDS is not…

Advanced mathematics courses have been developed and refined by the first author, using an action research methodology, for more than a decade. These courses use the computer algebra system (CAS) Maple in an "immersion mode" where all presentations and student work are done using Maple. Assignments and examinations are Maple files downloaded from…

"Moodle[TM]," an acronym for Modular Object-Oriented Dynamic Learning Environment, is an open source software package that teachers can use to produce Internet-based courses and Web sites. "Open source" basically means that it is copyrighted, but it can be used at no cost as long as the user agrees to provide the source to others. "Moodle[TM]" can…

Two-level data sets are frequently encountered in social and behavioral science research. They arise when observations are drawn from a known hierarchical structure, such as when individuals are randomly drawn from groups that are randomly drawn from a target population. Although 2-level data analysis in the context of structural equation modeling…

Students have cheated for centuries, but the problem is knottier than it used to be. The Internet and its infinite dishonest shortcuts have made many cases more complex, and antiplagiarism software like Turnitin flags more potential offenses than could be caught before. At the same time, professors' and college presidents' run-ins with plagiarism…

Multi-ball collisions inside the Astroblaster toy are explained from the conservation of momentum point of view. The important role of the coefficient of restitution is demonstrated in ideal and real cases. Real experimental results with the simple toy can be compared with a computer model represented by an interactive Java applet. (Contains 1…

Technology may not be a magic wand, but innovative technology programming can genuinely help children become adept at navigating our increasingly wired world while also helping them develop deductive reasoning, math, and other vital literacy skills. One of the simplest and most powerful tools for technology-based public library programming is…

As extensive reading becomes more commonplace in the EFL/ESL classroom, there is a rise in the number of instructors and administrators who are looking for cost-effective and space-saving methods to carry out extensive reading activities. Two extensive reading systems to respond to such concerns were developed with the support of a Grant-in-Aid…
