White, Tobin – Cognition and Instruction, 2019
This article analyzes an episode of classroom mathematics activity mediated by graphing technology from 3 different theoretical perspectives. An important line of research in the learning sciences focuses on graphs as "inscriptions", foregrounding learners' interactions with and around the material properties of graphical displays.…

Bennett, Blake; Hurley, Janet; Merchant, Mike – Journal of Extension, 2016
Having the ability to assess pest problems in schools is essential for a successful integrated pest management (IPM) program. However, such expertise can be costly and is not available to all school districts across the United States. The web-based IPM Calculator was developed to address this problem. By answering questions about the condition of…

Cerreta, Pietro – Science & Education, 2014
The Gravity-Powered Calculator is an exhibit of the Exploratorium in San Francisco. It is presented by its American creators as an amazing device that extracts the square roots of numbers, using only the force of gravity. But if you analyze his concept construction one can not help but recall the research of Galileo on falling bodies, the inclined…

White, Tobin – North American Chapter of the International Group for the Psychology of Mathematics Education, 2013
This paper explores the potential of mobile devices to support novel forms of mathematics classroom activity. In particular, I consider two salient aspects of contemporary practice with mobiles--networking/communication, and picture taking--and explore technology designs that might exploit their potential for supporting related forms of…
