Simulation is an effective tool for analyzing probability models as well as for facilitating understanding of concepts in probability and statistics. Unfortunately, implementing a simulation from scratch often requires users to think about programming issues that are not relevant to the simulation itself. We have developed a Python package called…

Unlike the situated learning within traditional clinical placements, mixed-reality simulations support a laboratory learning environment where preservice teachers practice their instruction with low risk to the preservice teachers and human students. Simulation experiences can be used in teacher education programs to prepare candidates for the…

This working group addresses the challenge and opportunity presented by the use of simulations of teaching practice as an educative tool for preservice and practicing teachers. We focus particularly on the development of teachers' skills in enacting the content-intensive work of teaching, including how simulations may be able to cultivate or…

We analyzed 5th grade students' interactions with one computer-based modeling simulation to examine how they defined and prioritized variables in a dynamically simulated environment. Results revealed that exposure to the simulation environment helped students visualize continuous motions, interpret the different quantities present in the model,…

The purpose of this study was to explore students' mathematical practices while working on modeling problems using 3 interactive computer simulations. Three fifth grade students' interactions with computer-based modeling simulation were examined to identify how children defined and prioritized and coordinated variables and parameters in…

Recent articles in the news media have triggered interest in how virtual reality technologies can be applied to academic libraries. Specifically, virtual reality technologies have the potential to be applied to triage reference, reference services, and archives. It is discussed how library users can use virtual reality headsets as well as how…

The purpose of this study is to explore factors that affect exclusively physical, virtual and both a Virtual-Physical (VP) and Physical-Virtual (PV) sequence of manipulatives within Studio Physics environment. In this environment students actively work together to learn through real world experimentation and simulation based activities. Activities…

The emphases of student involvement and meaningful engagement in the learner-centered education model have created a new paradigm in an effort to generate a more engaging learning environment. This study examines the success of using different simulation platforms in creating a market simulation to teach business processes in the accounting…

Meta-analyses often include only a small number of studies ([less than or equal to]5). Estimating between-study heterogeneity is difficult in this situation. An inaccurate estimation of heterogeneity can result in biased effect estimates and too narrow confidence intervals. The beta-binominal model has shown good statistical properties for…

The authors explore how 3D visualizations of historical sites can be used as pedagogical tools to support historical empathy. They provide three visualizations created by a team at Virginia Tech as examples. They discuss virtual environments and how the digital restoration process is applied. They also define historical empathy, explain why it is…

A new app, freely available for Windows computers, has been developed to simulate tuning of an inductively coupled plasma mass spectrometer, on the basis of optimization data collected using a sector-field instrument. The app allows students to adjust parameters, including the torch position, gas flows, radio-frequency power, and guard-electrode…

On an enactivist conception of cognition, the unit of explanation is not just the brain, not just the body, and not just the environment, but the body--brain--environment understood as a dynamically coupled structure or gestalt. On this view, referencing Viktor von Weizsäcker's metaphor of the gestalt circle (Gestaltkreis), the brain is not in the…

The California Budget Challenge produced by Next10 provides a useful and intuitive tool for instructors to introduce students to public budgeting. Students will reason through a series of budgeting decisions using information provided on the fiscal and practical implications of their choices. The Challenge is updated with each budget cycle, so it…

This study examined the use of Bayesian analysis methods for the estimation of item parameters in a two-parameter logistic item response theory model. Using simulated data under various design conditions with both informative and non-informative priors, the parameter recovery of Bayesian analysis methods were examined. Overall results showed that…

This paper presents a computational model for simulating how people learn from serious games. While avoiding the combinatorial explosion of a games micro-states, the model offers a meso-level pathfinding approach, which is guided by cognitive flow theory and various concepts from learning sciences. It extends a basic, existing model by exposing…
