The communication and collaborative interface known as a multi-user virtual environment (MUVE), has existed since as early as the late 1970s. MUVEs refer to programs that have an animated character ("avatar") controlled by a user within a wider environment that can be explored--or built--at will. Second Life, a MUVE created by San Francisco-based…

Teaching the use of models in scientific research requires a description, in general terms, of how scientists actually use models in their research activities. This paper aims to arrive at defining common characteristics of models that are used in present-day scientific research. Initially, a list of common features of models and modelling, based…

In an interview, Dr. Deborah W. Proctor, eCurriculum Director for Academic Innovations/ Minnesota Online and Co-Chair for the MERLOT International Conference, outlines her academic path that led to her current position and interests. As e-Curriculum Director for Academic Innovations in the Office of the Chancellor she works with system…

This study, the purpose of which is to determine an efficient instructional design for different levels of spatial abilities, investigates: (1) the main effects of visual treatments in simulation environments on comprehension and the transfer of chemistry knowledge and (2) the interaction effects of the visual treatments and the learners' spatial…

Educators and education advocates have recently acknowledged that the ability to think systemically is one of the necessary skills for success in the 21st century. Game-making is especially well-suited to encouraging meta-level reflection on the skills and processes that designer-players use in building such systems. Membership in a community of…

The use of virtual environments for special needs is as diverse as the field of Special Education itself and the individuals it serves. Individuals with special needs often face challenges with attention, language, spatial abilities, memory, higher reasoning and knowledge acquisition. Research in the use of Virtual Learning Environments (VLE)…

Purpose: Applications of online Second Life (SL) prevail over the world. The purpose of this paper is to make a review and synthesis of recent research studies on SL. Design/methodology/approach: Documental analysis is employed. Totally, 135 research publications, published in 2006-2008, are reviewed and synthesized. Findings: Findings are as…

This paper reports findings of a pilot study that examined the pedagogical potential of "Second Life" (SL), a popular three-dimensional multi-user virtual environment (3-D MUVE) developed by the Linden Lab. The study is part of a 1-year research and development project titled "Modelling of Secondlife Environments"…

This paper discusses issues of representation in the use of scientific visualizations, specifically those used for biomedical applications, and the implications of those issues to interface design. Topics addressed include the benefits of research into the generation of virtual simulation (virtual reality) and the importance of realism. (Contains…

A probability distribution was developed for the Andrews-Pregibon (AP) statistic. The statistic, developed by D. F. Andrews and D. Pregibon (1978), identifies multivariate outliers. It is a ratio of the determinant of the data matrix with an observation deleted to the determinant of the entire data matrix. Although the AP statistic has been used…

This demonstration of the use of a computer simulation research method based on the System Dynamics modeling technique for studying distance education reviews research methods in distance education, including the broad categories of conceptual and case studies, and presents a rationale for the application of systems research in this area. The…

Original research is reported on image digitizing, robot choreography, movement analysis, databases for dance, computerized dance notation, and computerized lightboards for dance performance. Articles in this publication are as follows: (1) "The Evolution of Dance Technology" (Judith A. Gray); (2) "Toward a Language for Human Movement" (Thomas W.…

Interactive computer-generated simulations that highlight psychological principles were investigated in this study in which 33 female and 19 male undergraduate college student volunteers of median age 21 matched line and circle sizes in six variations of Ponzo's illusion. Prior to working with the illusions, data were collected based on subjects'…

A recurring problem in educational research is how to account for non-random selection that has restricted the range of the variables of interest in correlational analyses. Several expressions due to H. Pearson (1903) and presented in matrix notation by D. N. Lawley (1943-44) are commonly used in selection settings to adjust for samples chosen on…

Explains how computerized game-simulation experiments were conducted to ascertain responses to the 1980 eruptions of Mt. St. Helens (Washington). Results indicate different aspects of individual preferences and family decisions with respect to relocation: (1) highly consistent in the game simulation; (2) responsive to the simulated threat; and (3)…
