Everyday experience suggests that drivers are less susceptible to motion sickness than passengers. In the context of inertial motion (i.e., physical displacement), this effect has been confirmed in laboratory research using whole body motion devices. We asked whether a similar effect would occur in the context of simulated vehicles in a visual…

The draw of simulations is that by replicating a simplified version of reality they can illustrate the repercussions that individual choices create. Students can play the role of a judge, an ambassador, or a parliamentarian and can experience first hand how their decisions play out. As a discipline, we assume that such practices are an improvement…

The use of cadavers to teach anatomy is well established, but limitations with this approach have led to the introduction of alternative teaching methods. One such method is the use of three-dimensional virtual reality computer models. An interactive, three-dimensional computer model of human forearm anterior compartment musculoskeletal anatomy…

In this paper, we take a designer's look at how the activities and data of learning and assessment can be structured in immersive virtual game environments called Massively Multi-Player Online Games (MMOG). In doing so, we examine the channels of evidence through which learning and assessment activities are derived in MMOGs, offering examples of…

In this article, I recount the many ways in which Harold Guetzkow influenced my career. From the beginning of my graduate studies at Northwestern University in the 1960s into the next century, Harold's guidance has been indispensable. His idea of bridging islands of theory has provided many of us with a broad, integrated vision of social science.…

Seafloor exploration being done by scientists is an ideal way to introduce students to technology as a tool for inquiry. The same technology that allows scientists to share data in near real time can also provide students the tools to become researchers. NOAA's Ocean Explorer Explorations website is a rich research data bank that can be used by…

pi-Electron delocalization exerts one of the most significant structure or energy influences in organic chemistry. Apart from determining the shapes of alkenes and alkynes, the planarity of aromatic molecules is a hallmark of pi-electron delocalization. Huckel's rules for aromaticity are easily applied in the teaching of undergraduates, but…

The empirical study, in this article, involved 42 students (ages 14-15), who used the urban simulation computer game SimCity 4 to create models of sustainable future cities. The aim was to explore in what ways the simulated "real" worlds provided by this game could be a potential facilitator for science learning contexts. The topic investigated is…

In this case study a novel educational programme for students in preparatory vocational education was studied. The research questions were: (1) Which teaching/learning processes occur in a simulated workplace using the concept of a "knowledge-rich" workplace? (2) What is the role of models and modelling in the teaching/learning…

Unhappy with conditions in Second Life, educators are migrating to a developing virtual world that offers them greater autonomy and a safer platform for their students at far less a cost. OpenSimulator is an open source virtual world platform that schools can run for free on their own servers or can get cheaply and quickly--the space can be up and…

The development of appropriate scenarios is critical in high-fidelity simulation training. They need to be developed to address specific learning objectives, while not preventing other learning points from emerging. Buying a patient simulator, finding a volunteer to act as the patient, or even obtaining ready-made scenarios from another simulation…

Signal detection theory forms the core of many current models of cognition, including memory, choice, and categorization. However, the classic signal detection model presumes the a priori existence of fixed stimulus representations--usually Gaussian distributions--even when the observer has no experience with the task. Furthermore, the classic…

Laboratory experiments and computer models for studying the mass transfer process of removing CO2 from air using water or dilute NaOH solution as absorbent are presented. Models tie experiment to theory and give a visual representation of concentration profiles and also illustrate the two-film theory and the relative importance of various…

When kids play video games, they want to perfect their skills, advance to the next level, and become a master. It is the kind of focus that many teachers would love to see in their classrooms. From elementary through high school, computer games are being woven into the curriculum to engage students in new ways. However, many schools lack the…

It is common to consider Tukey's schematic ("full") boxplot as an informal test for the existence of outliers. While the procedure is useful, it should be used with caution, as at least 30% of samples from a normally-distributed population of any size will be flagged as containing an outlier, while for small samples (N less than 10) even extreme…
