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 this 15-week study the effects of motivational email messages on learner self-efficacy and achievement in an asynchronous math course were investigated. A repeated measures design was used. One hundred, ninety-six participants were randomly assigned to control and experimental groups. Specially designed email messages were sent weekly to both…

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…

There is a paucity of research concerning the opinions and roles of Department Chairs pertaining to computer use, yet these individuals are in a key position to influence the curricula. The purpose of this survey was to improve understandings about Department Chairs' opinions and reported practices concerning computer applications in their…

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…

The promotion of e-learning in policies internationally has led to questions about how best to employ technology in support of learning. A range of models has since been developed that attempts to relate pedagogy to technology. However, research into the effectiveness of such models in changing teaching practice is sparse, and work that compares…

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…

This paper explores the potential for wiki-type open architecture software to promote and support collaborative learning through the use of student-created content. It delineates some of the affordances and constraints of wiki software as an open architecture that has the potential to facilitate collaborative learning through community-focused…

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…
