The following is a special contribution to this blog by Jenn Wortman Vaughan, a senior researcher at Microsoft Research.   Social computing encompasses the mechanisms through which people interact with computational systems like crowdsourcing markets, ranking and recommendation systems, online prediction markets, citizen science projects, and collaboratively edited wikis. Humans are active participants in these systems, making choices that determine the systems’ input, and therefore output. The output of these systems can be viewed as a joint computation between humans and machines, and can be richer than what either could produce alone. Social computing is blossoming into a rich research area, with contributions from diverse disciplines including computer science, economics, […]

The CCC Computer-Aided Personalized Education (CAPE) Workshop will be held in Washington, DC on November 12-13th. The demand for education in STEM fields is exploding, and universities and colleges are straining to satisfy this demand. In the case of Computer Science, for example, the number of US students enrolled in introductory courses has grown three-fold in the past decade. Recently massive open online courses (MOOCs) have been promoted as a way to ease this strain, but scaling traditional models of teaching to MOOCs poses many of the same challenges observed in the overflowing classrooms, namely, assessment of students’ knowledge and providing meaningful feedback to individual students. To tackle these problems […]
