In this paper we present a brokerage system for using idle computing resources as a micro-currency for Web services hardly quantifyable with real currencies as downloading stock charts or accessing a search engine. The Locust (LOw cost Computing...

Interest in the instructional application of virtual worlds, such as Second Life, has grown significantly. However, little information is available about effective instructional activities using virtual worlds. This case study illustrates lessons...

Using a framework of cognitive, social, and teaching presence, the nature of learning experiences in a three-dimensional virtual world environment (Second Life) and a text-chat learning environment without visuals (TeachNet) were investigated. A...

While many reports espouse the potential impact that 3-D virtual worlds are expected to have on teaching and learning in higher education in a few years, there are few empirical studies that inform instructional design and learning assessment in...

It has long been assumed that graphic organizers (GOs) should be presented to students following text as an organizer, rather than preceding text as an overview. Robinson et al. ("Educational Technology Research & Development," 51(4), 25-41, 2003)...

Substantial evidence now supports pedagogical applications of virtual worlds; however, most research supporting virtual worlds for education has been conducted using researcher-developed Multi-User Virtual Environments (MUVE). Second Life (SL) is a...

This paper presents an empirical study of how Second Life (SL) was utilized for a highly successful project-based graduate interdisciplinary communication course. Researchers found that an integrated threefold approach emphasizing project-based...

This article describes live, online faculty development workshops that show faculty how to use software packages (to date, GAP and Maple) in teaching college-level mathematics. The authors' primary goal in this article is to encourage others in any...

The "WVEB" Mathematics Project is a collaborative program offering college-level courses to high school students. Results of a matched-pair study comparing on- and off-campus students in algebra indicate that both sections show a significant gain in ...

In 2 experiments, 241 undergraduates with low domain knowledge viewed a tutorial on how to use Packet Tracer (PT), a computer-networking training simulation developed by the Cisco Networking Academy. Participants were then tested on retention of...

We investigated the effects of feedback and collaboration on undergraduates' transfer performance when using a computer networking training simulation. In Experiment 1, 65 computer science "novices" worked through an instructional protocol...
