Yes, video games are mainly for play and fun. But video games are educative as well as interesting and engaging—something that we all hope that more classrooms could be. Many of today's students spend more time playing video games than they do watching television, reading books, or watching films. Massively multiplayer online games (MMOGs)—long and surprisingly complex gaming environments that ...

The purpose of the following study was to develop a comprehensive, theory-based framework for creating instructional video podcasts designed to present worked examples. Sixteen design characteristics, organized according to four categories (establishing context, providing effective explanations, minimizing cognitive load, and engaging students), were used to develop 59 pre-calculus videos for 8...

A Web-based instructional project for the study of motor coordination is presented. The project includes two components: a tutorial on motor coordination and an interactive digitized video image system developed for the analysis of motion, including topics in biomechanics, motor coordination, motor control, and motor skill. This interactive system allows for the quantitative analysis of stored ...

In this investigation we assessed whether different formats of media influenced participants’ engagement and recall of narrative cases of people diagnosed with HIV/AIDS. For each of the personal case-narratives used in the study, we designed three informationally-equivalent versions: one video, one text, and one video + text. Thirty participants experienced one version in each format, completed...

We present a fast video retrieval system with three novel characteristics. First, it exploits the methods of machine learning to construct automatically a hierarchy of small subsets of features that are progressively more useful for indexing. These subsets are induced by a new heuristic method called SortMerge feature selection, which exploits a novel combination of Fastmap for dimensionality r...

Community and social relationships are an important part of yoga and meditation despite the fact that they are commonly perceived as solitary activities. Family members and loved ones often share activities and experiences over video chat technology to sustain their relationships across distance, and we wondered if similar technology could allow for yoga and meditation partners to share their p...
