This paper suggests a pedagogical approach to teaching the subject of average modeling of PWM switch-mode power electronics systems through simulation by general-purpose electronic circuit simulators. The paper discusses the derivation of PSPICE/ORCAD-compatible average models of the switch-mode power stages, their software implementation, and…

Significant responsibility for the transition from paper to online can be traced to the college admissions office. By instituting online applications, admissions offices fundamentally altered the way in which college admissions works. Always on the forefront of developing and implementing new technology for the benefit of faculty and students,…

The Personal Inquiry project is an investigation into the role that technologies can play in enabling effective inquiry. While it is generally agreed that inquiry-based learning has potential for student learning, especially in science, three main challenges remain. The first is to provide effective support for inquiry learning, for both students…

The purpose of this paper is to familiarize instructional designers and researchers with a useful design and research paradigm known as "Ask Systems." Ask Systems are interrogative interfaces to information and learning environments that model conversations with a skilled, reflective practitioner (Schon, The reflective practitioner, "1983") or…

The provision of accurate, in-depth data on substance abuse trends and service needs has become increasingly important in light of the growing wave of substance abuse in South Africa and particularly in the Western Cape Province. This article describes the design and implementation of an electronic substance abuse surveillance system (SASS)…

Video connects sight and sound, creating a composite experience greater than either alone. More than any other single technology, video is the most powerful way to communicate with others--and an ideal medium for sharing with others the vital learning occurring in music classrooms. In this article, the author leads readers through the process of…

This paper proposes modelling based learning as a tool for learning and teaching mathematics in high school. We report on an example of modelling real world problems in two high schools in Serbia where students were introduced for the first time to the basic concepts of modelling. Student use of computers and educational software, GeoGebra, was…

When students miss classes for university activities such as athletic and academic events, they inevitably miss important class material. Students can get notes from their peers or visit professors to find out what they missed, but when students miss new and challenging material these steps are sometimes not enough. Screen capture and recording…

The revolutionary electronic reading device, Amazon's Kindle, is already obsolete. Such is the breakneck speed of technology that the machine touted to spell the death of printed books is already heading for the scrap heap, replaced by e-readers like the iPad that access the Internet, make phone calls, download movies, and connect users with all…

Seasoned educators use an assortment of student-centered methods and tools to enhance their student's learning environment. In respects to methodologies used in accounting, educators have utilized and created new forms of problem-based learning exercises, including case studies, simulations, and other projects, to help students become more active…

We compiled a geo-referenced bibliography of research including theses, peer-reviewed articles, agency literature, and books having sample collection sites in and around Coos Bay, Oregon. Using Google Earth and GeoCommons we created a map that allows users such as visiting researchers, faculty, students, and local agencies to identify previous…

We present a low-cost, fully computer-controlled, Arduino-based, educational laboratory (SolarInsight) to be used in undergraduate university courses concerned with electrical engineering and physics. The major goal of the system is to provide students with the necessary instrumentation, software tools and methodology in order to learn fundamental…

Digital learning, supporters say, has the power to help prepare students for the workforce, improve student learning and educator effectiveness, and bring high-quality education to those who can't otherwise access it. However, great variability exists among schools and districts in terms of level of development and needs. This policy brief serves…

Automatic item generation represents a relatively new but rapidly evolving research area where cognitive and psychometric theories are used to produce tests that include items generated using computer technology. Automatic item generation requires two steps. First, test development specialists create item models, which are comparable to templates…

A number of free Web-based tools are available for distance librarians to create presentations and online assignments. The relative merits of presentation tools like Dabbleboard, Jing, Prezi, Tildee, 280 Slides, and Glogster, and classroom tools like Make Beliefs Comix, Picviewer, Photopeach, and Wordle are assessed for ease of use by distance…
