TeraGrid is a national-scale computational science facility supported through a partnership among thirteen institutions, with funding from the US National Science Foundation [1]. Initially created through a Major Research Equipment Facilities Construction (MREFC [2]) award in 2001, the TeraGrid facility began providing production computing, storage,(More)
We report an initial study on the use of visuohaptic simulation in teaching STEM (Science, Technology, Engineering and Mathematics) topics, with particular emphasis on physics concepts related to the learning of nanotechnology at the undergraduate level. Visuohaptic simulations of point charges and their interactions were developed. Thirty-eight(More)
One element of using contemporary computer graphics tools is the creation of accurate 3D geometry for a variety of purposes. As part of developing effective instructional experiences for students engaged in such activities, computer graphics educators must take into account a person's spatial abilities and skills. Literature has shown these abilities are(More)
Computer graphics is a powerful medium used to communicate information and knowledge. It is a discipline whose time has come. Until recently it was a mysterious specialty involving expensive display hardware, considerable computing resources, and specialized software. In the last few years, computer graphics has found its way into the mainstream of society,(More)
The present study investigated the use of visual trajectory and haptic force information in learning concepts involving force. Specifically, learning modules for instructing buoyant forces were developed for use with a computer monitor and a force feedback device. Students from an elementary school at the fourth and sixth grades were recruited to(More)
What is it? Purdue University's Distributed Rendering Environment (DRE) is a forward-looking application of grid computing for teaching and learning. Generating images from data—a process known as " rendering " —requires a great deal of computer processing power. As part of the Purdue High Performance Classroom initiative, the DRE allows students to render(More)
