A discussion on how a spreadsheet simulation of linear-molecular spectra could be used to explore the dependence of rotational band spacing and contours on average bond lengths in the initial and final quantum states is presented. The simulation of hydrogen chloride IR, iodine UV-vis, and nitrogen UV-vis spectra clearly show whether the average…

The study of measurement models in psychometrics by means of dimensionality reduction techniques such as Principal Components Analysis (PCA) is a very common practice. In recent times, an upsurge of interest in the study of artificial neural networks apt to computing a principal component extraction has been observed. Despite this interest, the…

This study investigated the potential accident-proneness of adolescents with attention deficit hyperactivity disorder (ADHD) in a hazardous road-crossing environment. An immersive virtual reality traffic gap-choice task was used to determine whether ADHD adolescents show more unsafe road-crossing behavior than controls. Participants (ages 13 to…

A need exists for a controlled examination of the variables that may affect the results of a behavior-based safety program. These include the rate of risky behaviors and how they relate to a contingent bonus payout (Experiment 1), and the relative amounts of honesty in injury reporting and rule following (Experiment 2). A simple task consisting of…

This article empirically supports the thesis that there is no clear and unequivocal argument in favor of simulations and experiential learning. Instead the effectiveness of simulation-based learning methods depends strongly on the target group's characteristics. Two methods of supporting experiential learning are compared in two different complex…

Project-based learning is not a new idea. It has a solid track record of increasing student motivation and improving students' problem-solving and higher-order thinking skills (Stites, 1998; Thomas, 2000). In the traditional model, students work in teams to investigate open-ended questions and apply their knowledge through culminating products or…

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…

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…

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)…

The 370 conference papers on information technology and teacher education are presented in two volumes. The 183 papers in the first volume include the following topics: use and evaluation of educational software; preservice and inservice training issues; multimedia portfolios; distance education; diversity and international perspectives; the…

Societal changes demand educators to apply new pedagogical approaches. Many educational stakeholders feel that serious games could play a key role in fulfilling this demand, and they lick their chops when looking at the booming industry of leisure games. However, current toolkits for developing leisure games show severe shortcomings when applied…

As part of the project titled "Hands-On Heads-On: The Effective Use of Manipulatives Both Virtual and Physical" being undertaken at Edith Cowan University, there was an investigation into the use of virtual manipulatives and the interactive whiteboard (IWB). Virtual manipulatives may be defined as a virtual representation of a physical…

Safari is a cooperative project involving four Quebec universities, two industrial partners (Virtual Prototypes, Inc., providing the VAPS software package, and Novasys, Inc., a consulting firm specializing in artificial intelligence and training), and government. VAPS (Virtual Applications Prototyping System) is a commercial interface-building and…

This paper describes a case study/client scenario approach used in an advanced medical/surgical nursing course; its methods of interactive learning are facilitated by the computer technology available in a "master classroom." This approach incorporates concepts of adult learning theory and creativity and group interaction. The equipment,…

A dilemma in designing computer simulations for instruction is how to provide a challenging exploratory environment and yet provide sufficient support so that students do not become lost. Directive support such as corrective feedback may detract from the exploratory quality of a simulation. Two methods of non-directive support are: (1) simplifying…
