As adult office workers' use of computers has increased, the incidence of computer-related musculoskeletal complaints and injuries has also increased. Although the use of computers in the classroom is increasing, little attention has been paid by educators, furniture manufacturers, or researchers to the ergonomic design issues of educational…

In this enlightening volume, expert educator Robert Sylvester explains how adults can better understand teenagers through an engaging discussion of the adolescent brain. Readers will learn how to: (1) Mentor adolescents rather than attempt to manage and control them; (2) Nurture creativity, imagination, and individuality; and (3) Understand such…

This issue of "The Evaluation Exchange" describes new developments in evaluating advocacy and policy change efforts that attempt to inform or influence public policy at the local, state, or federal levels. Heather B. Weiss introduces the themes in this issue in "From the Director's Desk," examining how evaluation of advocacy…

Teenagers are perplexing, intriguing, and spirited creatures. In an attempt to discover the secrets to their thoughts and actions, parents have tried talking, cajoling, and begging them for answers. The result has usually been just more confusion. Light is being shed on these mysterious young adults. What was once thought to be hormones run amuck…

Because a significant portion of U.S. students lacks critical mathematic skills, schools across the country are investing heavily in computerized curriculums as a way to enhance education output, even though there is surprisingly little evidence that they actually improve student achievement. In this paper we present results from a randomized…

This paper evaluates the effectiveness of a student controlled computer program for high school mathematics based on instruction principles derived from Schoenfeld's theory of problem solving. The computer program allows students to choose problems and to make use of hints during different episodes of solving problems. Crucial episodes are:…

Computer-mediated conferencing has been adopted, particularly for purposes of online course provision, as a method that can deliver community. Widespread interest in a communities-of-practice approach within both informal and formal learning has strengthened perceptions of the value of creating a community online. A case study of asynchronous…

This article explores the development and evaluation of the graduate-level Early Childhood Development Virtual University (ECDVU) programme in Sub-Saharan Africa from 2001 through to 2004. It outlines the history of the ECDVU and the establishing of a Sub-Saharan programme for future leaders in the early childhood field guided by the key principle…

This article provides guidance for meeting the educational needs of "learners on the periphery"--those learners who traditionally have been disenfranchised by formal education because of the structure and nature of face-to-face courses but who now may be returning to higher education due to the promises of the online classroom. The guidance comes…

This article examines the online discourse that took place in representative threads from two classes, seeking to document indicators that students did or did not engage in co-construction of knowledge. Stahl's (2006) social theory of computer supported collaborative learning (CSCL) is used along with discourse analysis methods to examine these…

More and more, adult learners are finding the convenience and flexibility of online learning a match for their learning goals and busy lifestyles. Online degree programs, courses, and virtual universities targeting adult learners have proliferated in the past decade. Although students can easily locate an online course or degree program that's…

This paper presents a methodology designed to explore the role of context in collaborative knowledge construction activity in asynchronous web-based discussion. The discussions of two student groups participating in a web-based teacher education course were compared. The comparison aimed to highlight the differences and similarities between the…

The first section of this article examines a range of definitions of biotechnology. This analysis demonstrates that teachers' choices will determine their view of biotechnology, as positioned along a traditional-modern, axis, and provides examples of the tensions that these differing positions create. A further section argues that in order for…

In this article I discuss the emergence of practices of "hearing" in the midst of English language learning activities. I focus on listening activities during oral English lessons at two public high schools in Tokyo, Japan. One setting is a liberal arts high school. The other is a technical high school where students are trained in…

Research literature on students as researchers demonstrates a spectrum of constructive ways in which students are being actively engaged in school and classroom action inquiries. Any identified tensions lie in the degree to which students themselves are genuinely engaged as action researchers. Increasingly, externally driven agendas for change and…
