The author acknowledges that there is often a gap in how and for what ends technology is used--a gap between some students and their teachers and a gap among different groups of students. What is less obvious is the nature of these gaps in terms of literacy practices. He then asks, "Could we be missing ways to connect with our students and help…

In this study, we explore an alternate mode for teaching and learning the dynamic, three-dimensional (3D) relationships that are central to understanding astronomical concepts. To this end, we implemented an innovative undergraduate course in which we used inexpensive computer modeling tools. As the second of a two-paper series, this report…

This document focuses on the writing skills of college students. The days of students sifting through piles of file cards, producing detailed outlines, and handwriting drafts have slipped into the distant past. Students write quickly and casually with the assistance of technology, and common sense dictates that technology needs to be used to teach…

In this article, I examine distributed scaffolding, an emerging approach in the design of supports for rich learning environments intended to help students develop disciplinary ways of knowing, doing, and communicating. Distributed scaffolding incorporates multiple forms of support that are provided through different means to address the complex…

Educators have been wrestling with copyright issues for some time. In fact, in developing the S.O.S. for Information Literacy site, the project team had to face the issue with respect to how to handle all those lesson plans in the database and all the images, clipart, and materials that educators upload to the database as support materials for…

The need for designing the next generation of web service-based educational systems with the ability of integrating components from different tools and platforms is now recognised as the major challenge in advanced learning technologies. In this paper, we discuss this issue and we present the conceptual design of such environment, referred to as…
