Sixty-five teams of basic and secondary school students solved problem-solving tasks during a virtual hike in a Web-based inquiry-learning simulation Hiking Across Estonia. This environment provided learners with all necessary background information for problem-solving and tools for carrying out experiments. There were 25 tasks in certain order…

This study explored visual control strategies for braking to avoid collision by manipulating information about speed of self-motion. Participants watched computer-generated displays and used a brake to stop at an object in the path of motion. Global optic flow rate and edge rate were manipulated by adjusting eyeheight and ground-texture size.…

Part of the history of oil and gas development on Indian reservations concerns potential underpayment of royalties due to under-valuation of production by oil companies. This paper discusses a model used by the Shoshone and Arapaho tribes in a lawsuit against the Federal government, claiming the Government failed to collect adequate royalties.…

The human brain contains an estimated 100 billion neurons, and browsing the Web, one might be led to believe that there's a Web site for every one of those cells. It's no surprise that there are lots of Web sites concerning the nervous system. After all, the human brain is toward the top of nearly everyone's list of favorite organs and of…

This paper reports a study designed to probe the abstraction ability that US Algebra I students can achieve in moving the concepts rate of change and accumulation between motion and money contexts. The Algebra I students used the technologies motion detectors and Interactive Banking software during a replacement unit focused on slope, ratio, and…

As the evidence of the benefits of multidisciplinary education accumulates many schools and instructors are finding ways of hybridizing courses to include substantial components of what are otherwise distinct sciences. Often, such course development is done with an eye toward industry, which requires a workforce capable of synthesizing varied…

This study examined the effect of physical and virtual field trips on undergraduate, nonscience majors. No significant differences were seen in achievement, attitudes, learning styles, interactions between field trip and learning styles, or students' ability to answer questions at different levels. Results imply that both field trips promote…

The ability to design and to aspire of the future design of three-dimensional molecular animations to teach molecular symmetry is an exciting outcome of computer-driven technologies. Some of the details and vital issues addressed in developing a set of Web pages to teach molecular symmetry at Imperial College London using crafted animations are…

Leadership is often described as something that is learned from experience. However, experiences do not often occur within a controlled environment where learning and its impact can be evaluated. In this paper, we investigate the efficacy of two types of learning experiences. University students received leadership training of equal length through…

A simple, guided-inquiry investigation using stacked sandwich cookies is employed to develop a simple linear mathematical model and to explore measurement error by incorporating errors as part of the investigation. Both random and systematic errors are presented. The model and errors are then investigated further by engaging with an interactive…

This study examined the effect of scaffolding learning components in a computerized environment, for students solving qualitative science problems in a simulation of laboratory experiments. Four scaffolding components were identified (structural, reflective, subject-matter and enrichment) and used in different configurations to construct four…

This article identifies three uses of educational technology and evaluates their potential to change curricula and pedagogic strategies. The article is in four parts, with the first outlining a temporal model of change and discussing educators' expectations of continuities and discontinuities in practice. In order to distinguish minor…

The following paper presents a computer-based learning strategy to assist in introducing and teaching water quality modelling to undergraduate civil engineering students. As part of the learning strategy, an interactive computer-based instructional (CBI) aid was specifically developed to assist students to set up, run and analyse the output from a…

Lifelike, interactive digital characters, serving as mentors and role-playing actors, have been shown to significantly improve learner motivation and retention. However, the cost of modeling such characters, authoring and editing their interactions, and delivering them over limited-bandwidth connections can be prohibitive. This paper describes a…

The significant increase of English Language Learners (ELLs) in the United States raises complex questions about how to provide these students with access to high quality education that can improve both their content knowledge of school subjects and their English proficiency, particularly their academic English proficiency. The development of…
