This mixed-methods study explored the use of an augmented reality, location-based, iPad game to enhance the learning experience of young elementary history students. Utilizing the ARIS platform and a design-based research approach, researchers and teachers built a customized game experience that was inserted into a school's traditional second…

As countries become increasingly multicultural, it can be argued that the authentic teaching and learning of multicultural music in educational settings is essential. Crucial to this is the provision of cultural context to retain as much of the original meaning of the music as possible. This paper discusses the main arguments for authenticity in…

In a randomized controlled trial, a decision needs to be made about the total number of subjects for adequate statistical power. One way to increase the power of a trial is by including a predictive covariate in the model. In this article, the effects of various covariate adjustment strategies on increasing the power is studied for discrete-time…

This article describes an activity in which students will be able to apply rhetorical theory effectively and critically from specific theorists throughout history to modern-day issues. Through a simulated trial of a current figure, this activity makes connections between rhetorical theories to current affairs, thereby inviting students to consider…

There is a need for valid methods to assess the readiness for clinical practice of medical graduates. This study evaluates the validity of Utrecht Hamburg Trainee Responsibility for Unfamiliar Situations Test (UHTRUST), an authentic simulation procedure to assess whether medical trainees are ready to be entrusted with unfamiliar clinical tasks…

Purpose: The purpose of this study was to evaluate the effects of error experience on the acquisition of hypernasal speech. Method: Twenty-eight healthy participants were asked to simulate hypernasality in either an "errorless learning" condition (in which the possibility for errors was limited) or an "errorful learning"…

Purpose: This study examined the effects of envelope dynamic-range mismatch on the intelligibility of Mandarin speech in noise by simulated bilateral electric hearing. Method: Noise-vocoded Mandarin speech, corrupted by speech-shaped noise at 5 and 0 dB signal-to-noise ratios, was presented unilaterally or bilaterally to 10 normal-hearing…

In suspected child sexual abuse some professionals recommend multiple child interviews to increase the likelihood of disclosure or more details to improve decision-making and increase convictions. We modeled the yield of a policy of routinely conducting multiple child interviews and increased convictions. Our decision tree reflected the path of a…

John Lester is currently the chief learning officer at ReactionGrid, a software company developing 3-D simulations and multiuser virtual world platforms. Lester's background includes working with Linden Lab on Second Life's education activities and neuroscience research. His primary focus is on collaborative learning and instructional…

During the 17th century the idea of an orbiting and rotating Earth became increasingly popular, but opponents of this view continued to point out that the theory had observable consequences that had never, in fact, been observed. Why, for instance, had astronomers failed to detect the annual parallax of the stars that "must" occur if…

This teacher-research study responds to the Common Core State Standards (CCSS) call for an integrated model of literacy that simultaneously builds deep content knowledge and develops students' proficiency in writing arguments in science. The author notes that while argument is a cornerstone of the CCSS writing standards, little attention is…

A web-enabled computer simulation program presents real-world opportunities, problems, and challenges for aspiring principals. The simulation challenges areas that are not always covered in lectures, textbooks, or workshops. For example, using the simulation requires dealing--on-screen and in real time--with demanding parents, observing…

This paper presents a study focused on comparing real actors based scenarios and animated characters based scenarios with respect to their similarity in evoking psychophysiological activity for certain events by measuring galvanic skin response (GSR). In the experiment, one group (n = 11) watched the real actors' film whereas another group (n…

WebQuests have been a popular alternative for collaborative group work that utilizes internet resources, but studies have questioned how effective they are in challenging students to use higher order thinking processes that involve creative problem solving. This article explains how different levels of inquiry relate to categories of learning…

Computer simulations (we use the word liberally here to include applets, animations, apps, etc.) have been making steady progress as teaching tools. Large collections of simulations, created by individuals and by groups, are freely available. More recently, research on the effectiveness of simulations as teaching tools, particularly focused on the…
