In this article, the author describes how she was able to allow her students to talk with author Cynthia Leitich Smith through Skype, a free Internet telephony service. The author also describes how Skype can be used for recording podcasts and enhancing the reference services of libraries. Here, the author shares ideas on using Skype in libraries.

This article shows how to use six parameters describing the International Space Station's orbit to predict when and in what part of the sky observers can look for the station as it passes over their location. The method requires only a good background in trigonometry and some familiarity with elementary vector and matrix operations. An included…

This paper presents a conceptual analysis of the technological dimensions related to the operationalization of CSCL macro-scripts. CSCL scripts are activity models that aim at enhancing the probability that knowledge generative interactions such as conflict resolution, explanation or mutual regulation occur during the collaboration process. We…

Mathematical software packages such as Polymath, MATLAB, and Mathcad are currently widely used for engineering problem solving. Applications of several of these packages to typical chemical engineering problems have been demonstrated by Cutlip, et al. The main characteristic of these packages is that they provide a "problem-solving environment…

Data projectors have become a common sight in school classrooms, often in conjunction with an interactive whiteboard. Long periods of continuous use coupled with the transfer of a large amount of thermal energy from the projector's bulb means that they frequently break down, often in such a manner that they become uneconomic to repair. In this…

This article allows students to apply their knowledge and experience of area and volume to find the volume of Norris Lake, a large reservoir lake in Tennessee. Students have the opportunity to demonstrate their skills in using maps and scales as well as to incorporate the use of technology in developing the solution. This project satisfied the…

When it comes to technologies like digital games, simulations, and social networking, teachers and students may find themselves at cross purposes. Often, students find that these technologies, so prevalent in their lives outside of school, are unwelcome in their classrooms. Many teachers can tell stories about the disruptive influence of video…

Solving indeterminate algebraic equations in integers is a classic topic in the mathematics curricula across grades. At the undergraduate level, the study of solutions of non-linear equations of this kind can be motivated by the use of technology. This article shows how the unity of geometric contextualization and spreadsheet-based amplification…

In a geometry content course for pre-service elementary teachers, technology was utilized to assist students in making sense of shapes. They learned to write simple procedures in Logo that would program a turtle to draw various quadrilaterals. In the context of writing these procedures, the pre-service teachers used variables to represent the…

Today, "lifelong learning" encompasses a wide range of student profiles and curricular designs, but a growing subset of the nation's life-long learning programs are non-credit and designed specifically for students over the age of 50. The good news is that "over 50" does not mean "out of the technology loop." In this article, the author discusses…

To help teachers enrich their students' understanding of inquiry in Earth science, this article describes six modes of inquiry used by practicing geoscientists (Earth scientists). Each mode of inquiry is illustrated by using examples of seminal or pioneering research and provides pointers to investigations that enable students to experience these…

Students in the United States need diversity skills that enable them to function in an increasingly interdependent and varied world. Internet technology provides an untapped resource for assisting children to understand and value diversity. In this article, the authors present three skills that are important to students as they interact in the…

In this article, the author explains how early diagnosis of academic deficits is pivotal in keeping students from falling irretrievably behind. Twenty-first-century technology tools can have a major role in accomplishing this by helping with data collection, analysis, and classroom intervention. Here, the author describes how various schools…

As any ordinary person knows, the shortest distance between two points is a straight line. What, then, is the shortest distance between three points? Four points? The study reported in this article deals with the observed actions of Turkish student mathematics teachers as they were working with minimal network problems. Having analysed the…

In this article, the author discusses the major technical issues, products, and practices of the day. The top ten tech trends are listed and discussed. These include: (1) data mining; (2) cyberbullying; (3) 21st century skills; (4) digital content; (5) learning at leisure; (6) personal responders; (7) mobile tools; (8) bandwidth; (9) open-source…
