The nature of laboratory work has changed in the past decade. One example is a shift from working individually or in pairs on single traditional verification experiments to working collaboratively in larger groups in inquiry and research-based laboratories, over extended periods in and outside of the lab. In this increased era of collaboration, we…

Civil and natural resources engineering students at the University of Canterbury, New Zealand, take specific courses requiring small group research projects and the presentation of findings to staff and peers. Although one of the aims of these presentations is to assist in the development of the students' communication skills, staff have raised…

There is considerable interest in electric and hybrid cars because of environmental and climate change concerns, tougher fuel efficiency standards, and increasing dependence on imported oil. In this article, the author describes the history of electric vehicles in the automotive world and discusses the components of a hybrid electric vehicle.…

This study examined demographic and geographic variability in aggregated school-level data on the percentage of students achieving the FITNESSGRAM[R] Healthy Fitness Zones[TM] (HFZ). Three-way analyses of variance were used to examine differences in fitness achievement rates among schools that had distinct diversity and socioeconomic status…

The Functional Measurement approach, proposed within the theoretical framework of Information Integration Theory (Anderson, 1981, 1982), can be a useful multi-attribute analysis tool. Compared to the majority of statistical models, the averaging model can account for interaction effects without adding complexity. The R-Average method (Vidotto &…

The use of ICT to enhance teaching and learning depends on effective design, which operates at many levels of granularity from the small to the very large. This reflects the range of educational problems from course design down to the design of activities focused on specific learning objectives. For maximum impact these layers of design need to be…

Aim: The purpose of this study was to systematically review published evidence on the development, use, and effectiveness of devices and technologies that enable or enhance self-directed computer access by individuals with cerebral palsy (CP). Methods: Nine electronic databases were searched using keywords "computer", "software", "spastic",…

The authors tested the predictions of a game theory model of plagiarism, using a test population of student papers submitted to an online plagiarism detection program, over five semesters in a non-majors biology course with multiple sections and high enrollment. Consistent with the model, as the probability of detection and the penalty if caught…

Purpose: Many classroom educational assistants (EAs) have a significant amount of responsibility in carrying out educational plans for children who use augmentative and alternative communication (AAC), but they receive little instruction on how to do so (Kent-Walsh & Light, 2003). This study investigates the impact of using a communication partner…

Traditional ePortfolio systems are usually used as an individual learning unit, or an assessment tool in education. However, these systems often lack social constructivist learning features such as sharing, peer review, and group collaboration. This paper describes a new ePortfolio system that supports both personal and social constructivist…

Mobile devices offer unique opportunities to deliver learning content in authentic learning situations. Apart from being able to play various kinds of rich multimedia content, they offer new ways of tailoring information to the learner's situation or context. This paper presents the results of a study of mobile media delivery for language…

Today's classrooms are much different from those of yesterday. The increased diversity of learners, students' familiarity and attraction to technology, and the improved availability of technology in education have made it increasingly possible for teachers to use various forms of technology in instruction. The responsibility for addressing these…

This article describes the Project Lefty, a search system that, at a minimum, adds a layer on top of traditional federated search tools that will make the wait for results more worthwhile for researchers. At best, Project Lefty improves search queries and relevance rankings for web-scale discovery tools to make the results themselves more relevant…

A new procedure for performing quantitative measurements in teaching optics is presented. Application of the procedure to accurately measure the rate of change of the variable refractive index of a water-denatured alcohol mixture is described. The procedure can also be usefully exploited for measuring the constant refractive index of distilled…

In this study, a corpus of expert-graded essays, based on a standardized scoring rubric, is computationally evaluated so as to distinguish the differences between those essays that were rated as high and those rated as low. The automated tool, Coh-Metrix, is used to examine the degree to which high- and low-proficiency essays can be predicted by…
