Utility companies generate three-phase electric power, which consists of three sinusoidal voltages with phase angles of 0 degrees, 120 degrees, and 240 degrees. The ac generators described in most introductory textbooks are single-phase generators, so physics students are not likely to learn about three-phase power. I have developed a simple way…

In this note we show the existence of a surprising analogy between quadrilaterals and tetrahedra, determining some properties that hold for both families of figures. This analogy suggests some new properties of quadrilaterals. (Contains 11 figures,)

The television show Deal or No Deal and an Excel spreadsheet help students see how understanding probability and mean--and the concept of expected value (EV)--can lead to game show wins.

Use of interactive whiteboards (IWBs) in school classrooms and conference rooms is increasing. To evaluate the effectiveness of IWBs as a tool for Extension education, two groups of 3rd and 4th grade Minnesota students (n=325) were taught nutrition using traditional methods or IWBs. Significant increases in knowledge and behavior were observed in…

It's no secret that fewer and fewer women are entering computer science fields. Attracting high school girls to computer science is only part of the solution. Retaining them while they are in higher education or the workforce is also a challenge. To solve this, there is a need to show girls that computer science is a wide-open field that offers…

This paper presents a tool named "Interactive Attention Board" (IAB) and an associated software named "Interactive Attention Boards Software" (IABS) for individuals with Mental Retardation and Autism. The proposed system is based on several theories such as perception and learning theories, and it is intended to improve hand-eye coordination and…

In the spring of 2008, university students enrolled in courses at California State University, Long Beach (CSULB), and the University of Cyprus (UCY) participated in a cross-cultural e-learning project in which they studied American Indian literature and history. All students followed the same six-week syllabus, which included shared readings and…

The author and his colleague, Deborah Polin, traveled around the United States to get a first-hand look at how teachers are developing successful Web 2.0 activities for their classrooms. With funding from Intel, they interviewed 39 educators in 22 schools throughout the country about how they employed these tools in their classrooms in innovative…

The instructional design and the corresponding research on student learning of two virtual laboratories that provide an engineering task situated in an industrial context are described. In this problem-based learning environment, data are generated dynamically based on each student team's distinct choices of reactor parameters and measurements.…

A hybrid course of Molecular Symmetry and Group Theory which combines traditional face-to-face instruction with an online web enhanced learning environment within a Course Management System was designed, developed, and implemented with a purpose to establish an active and student-centred educational setting. Multi-representational educational…

In 2009, Colorado had the lowest rate of obesity and overweight in the United States with less than 20% of the adult population considered obese or overweight. The health implications are serious because being overweight and/or obese increases the risks for chronic diseases. As a consequence, the incidence of Type II diabetes in adults has tripled…

Handheld computers can leverage the power of technology to enable all students to succeed, including children with special education needs. They are cheaper than laptops, are more portable, and have more memory and power capabilities than handhelds possessed just five years ago. In this article, the author cites the various research he conducted…

In Part 1 ("TechTrends" 52.3), the authors described some of the easier kinds of animation such as Claymation, Pixillation, Cut Outs, People Pix, and FlipBook. Of these, FlipBook has the easiest learning curve. Now, in Part 2, they detail their first simple lesson in animation by describing how an entire classroom of students can create a group…

Blackboard has become the Microsoft of higher-education technology, say many campus-technology officials, and they do not mean the comparison as a compliment. To them the company is not only big, but also pushy, and many of them love to hate it. This article reports that a growing number of colleges are switching to Moodle, a free, open-source…

"Theoretical Foundations of Learning Environments" provides students, faculty, and instructional designers with a clear, concise introduction to the major pedagogical and psychological theories and their implications for the design of new learning environments for schools, universities, or corporations. Leading experts describe the most…
