Analyzes to what extent the computational model of the geometry implemented in a dynamic geometry environment provides models for physical motion, focusing on the continuity issues related to motion. Addresses the issue of the computable representation of knowledge. (Author/MM)

Technology offers a number of opportunities for connecting classrooms with the world. The advent of the Internet has offered unprecedented prospects for classroom connections, but the recent diffusion of digital cameras throughout society offers instructional possibilities as well. This document provides a detailed examination of digital…

On February 10, 2004, Alex Bick contacted Chris Dede, the Timothy E. Wirth Professor of Learning Technologies at the Harvard Graduate School of Education, seeking a mentor for his work to determine whether handheld computers regularly carried by high school students generally affect academic achievement. At the time, Bick was a 10th grader…

Studies show that recent generations of college students have a learning style with identifiable characteristics. Library instruction efforts must adapt to these learning styles. Course management software (CMS), such as Blackboard, is one resource available to academic librarians to meet the challenges posed by the ''Net Generation.'' At Stetson…

Many kinds of professional development exist within and across schools, but the IMPACT Model School Grant has provided enough professional development dollars to allow some "best practice" modifications to two common models that have reputations for being less than effective: conference attendance and outside consultants. The principal…

Personal digital assistants (PDAs, also known as handheld or palmtop computers) are, in this author's opinion, the next great step in educational technology. The educational community has spent countless hours and dollars on providing desktop or laptop computer access to PK-16 students. Most students now have some experience with the Internet,…

For largely historical reasons, information and communication technology in education has been heavily influenced by a form of constructivism based on the transmission and transformation of information. This approach has implications for both learning and teaching in the field. The assumptions underlying the approach are explored and a critique…

Finding Internet sites useful in the K-3 classroom and library can be a challenge. Between needing activities that will allow the users to be independent, searching for sites without a great deal of advertisements, and checking to be sure that any information gathered is kept private and respects the user's safety, it may b difficult to provide…

Once upon a time, there was the mainframe. Only a handful of applications were available on this great big computer. A few hearty users took advantage of these applications, often accessing them one at a time. Folks generally did not expect to use any application with another. Why would they? Now, of course, the world is very different. College…

A year ago, my colleague Charles Grisham and I wrote an EDUCAUSE Review article entitled "Why IT Has Not Paid Off As We Hoped (Yet)." In short, we argued that information technology has not yet transformed higher education because the areas of teaching and scholarship, the "heart" of colleges and universities, have remained relatively untouched by…

Have you ever heard, "If we could just find a good CIO, these problems would go away"? Certainly, having a strong and wise leader at the top of the IT organization is important; however, having such a person is not sufficient to effectively integrate IT into a key part of the institutional strategy. In a number of recent EDUCAUSE Review articles,…

Handheld computers give students access to the larger world of information beyond the classroom. Wireless access allows students real time access to all networks resources, including downloading e-books and documents, searching the library media centres catalog and searching databases to which the library has subscribed.

While using on-demand help features effectively in interactive learning environments has proven to have a positive effect on learning outcomes, most students are not using these features effectively. In a review of literature, the following factors were found to affect the use of on-demand help features: (a) a wide array of learning traits and…

In this article, the author believes that computers for young children are often reductive and limiting, rather than expanding their three dimensional sensory, interpersonal, and cognitive experience. Among other points, she discusses the after effects of children's early exposure to technological materials. Moreover, she opines that teachers need…

In Canada, both provincial and federal governments embraced educational techno-positivism with enthusiasm. However, a few critics pointed out that most of the enthusiasm for technology in the classroom came from dubious sources, including corporations that were (and still are) in pursuit of the almost unmeasurable revenue stream generated by…
