Recent changes to federal guidelines for the collection of data on race and ethnicity allow respondents to select multiple race categories. Redefining race subgroups in this manner poses problems for research spanning both sets of definitions. NAEP long-term trends have used the single-race subgroup definitions for over thirty years. Little is…

This study investigated perception of self-determination by special education and rehabilitation practitioners following their exposure to a videotaped simulation of a self-directed IEP meeting and an external-directed IEP meeting involving an adolescent with mild mental retardation. Groups of special education practitioners and rehabilitation…

In research concerning model invariance across populations, researchers have discussed the limitations of the conventional chi-square difference test ([Delta] chi-square test). There have been some research efforts in using goodness-of-fit indexes (i.e., [Delta]goodness-of-fit indexes) for assessing multisample model invariance, and some specific…

In this paper we analyse the behaviour of a small-scale model of a magnetic levitation system based on the Inductrack concept. Drag and lift forces acting on our prototype, moving above a continuous copper track, are studied analytically following a simple low-speed approach. The experimental results are in good agreement with the theoretical…

All too often, one reads about high-speed police chases in pursuit of stolen cars that result in death and injury to people and innocent bystanders. Isn't there another way to accomplish the apprehension of the thieves that does not put people at such great risk? This article presents a classroom challenge to use technology to remotely shutdown…

This paper reports on an investigation of student engagement with e-learning, using practitioner reflection as a lens. Five e-learning practitioners each provided a case study from their teaching, which was the focus of practitioners' reflective accounts. Each of the practitioners had used e-learning as a way of promoting both learning and…

This quantitative survey study examines the willingness of online students to adopt an immersive virtual environment as a classroom tool and compares this with their feelings about more traditional learning modes including our ANGEL learning management system and the Elluminate live Web conferencing tool. I surveyed 1,108 graduate students in…

Organizing and implementing telecollaboration projects in foreign language curricula is not an easy endeavour (Belz & Thorne, 2006; Guth & Helm, 2010), as pedagogical, organizational and technical issues have to be addressed before cross-cultural interaction sessions can be carried out (O'Dowd & Ritter, 2006). These issues make many teaching…

Virtual spaces allow abstract representations of reality that not only encourage student self-directed learning but also reinforce core content of the learning objective through visual metaphors not reproducible in the physical world. One of the advantages of such a space is the ability to escape the restrictions of the physical classroom, yet…

Three experiments examined whether the design of virtual learning environments influences undergraduates' enrollment intentions and anticipated success in introductory computer science courses. Changing the design of a virtual classroom--from one that conveys current computer science stereotypes to one that does not--significantly increased…

Purpose: This paper aims to identify methods of guidance and supervision used in air traffic control training. It also aims to show how these methods facilitate trainee participation in core work activities. Design/methodology/approach: The paper applies the tools of conversation analysis and ethnomethodology to explore the ways in which trainers…

The current meta-analysis study summarizes the effects of the GlobalEd Project, a web-based educational intervention of international negotiations embedded within social studies curricula, on middle and high school students' interest in social studies and negotiation self efficacy. Meta-analytic evidence supports statistically significant…

Background: In recent years, due to deliberate educational policy in various places around the world, children with dyslexia study in regular classes with non-dyslexic classmates. They do not appear handicapped, because their disabilities do not stem from physical deformities, and therefore, it is not easy to identify them in a group where the…

In this paper we present Geodromo, a prototype of an educational multimedia system, part of the Portuguese "Ciencia Viva" (Live Science) educational program, which is aimed at young people and designed with innovative characteristics. The project is based on a robotic multimedia simulator and an online puzzle game aimed at the…

Playing entertainment computer, video, and portable games, namely, digital games, is receiving more and more attention in academic research. Games are studied in different situations with numerous methods, but little is known about if and how the playing situation affects the user experience (UX) in games. In addition, it is hard to understand and…
