cRunch

calc a little, learn a lot.

cRunch is a service and an infrastructure for computationally-intense learning analytics. It supports researchers in munching away the data points, generated by learners online in the co-construction of knowledge. cRunch supports learners, faculty, and administration with living reports, created live from data.

cRunch currently has three components: the studio, the reports plus services, and the sharing facilities. The studio is a browser-based work space for exploratory data programming. It uses the simple to learn statistical programming language R � for data manipulation � and a wiki-like markup language called �markdown� � for the reports. cRunch reprots, however, are more than just text. We even call them �living documents�, as in addition to static text they also access live data executing live analytical scripts. cRunch services are kind of more complex reports, some of them intended for other machines rather than humans. The sharing facilities are the interface to the world. They help the community to remix, recycle, re-purpose data and code.
