Papers that use the E-Trials Testbed to run studies in ASSISTments.

Dr. Heffernan is not on an author on these papers. (There are nine other studies in which Heffernan is listed as an author).

I am proud of the fact that we let others propose studies to be run on our shared scientific instrument.
