This paper introduces a low-cost LEGO Mindstorms NXT motor system for teaching classical and modern control theories in standard third-year undergraduate courses. The LEGO motor system can be used in conjunction with MATLAB, Simulink, and several...
Youth development in a community technology center: Negotiation of “off-the-record-learning” with technology
Youth@development in a community@technology@center: Negotiation<p>of “off@-the@-record@-learning” with technology (2004) pp. 1–299
This dissertation is a study of how learning and development goals are organized within a community technology center (CTC) for youth called Teen TechArts. It describes the developmental processes made available to youth through opportunities to...

We present a data set consisting of user profile data for 59,946 San Francisco OkCupid users (a free online dating website) from June 2012. The data set includes typical user information, lifestyle variables, and text responses to 10 essay questions....
Learning to be better at the game: Performance vs. completion contingent reward for game-based learning
Computers & Education Vol. 139, No. 1 (October 2019) pp. 1–15
The difficulty of designing intrinsically integrated game-based learning systems has led to alternative design strategies based on extrinsic integration. This study extends prior work on extrinsic integration design by examining the effectiveness of ...
