Organize solutions into clusters and “force multiply” feedback provided by instructors
One of the hardest things about teaching a large class is grading exams and homework assignments. In my teaching days a “large class” was only in the few hundreds (still a challenge for the TAs and instructor). But in the age of MOOCs, classes with a few (hundred) thousand students aren’t unusual.
Researchers at Stanford recently combed through over one million homework submissions from a large MOOC class offered in 2011. Students in the machine-learning course submitted programming code for assignments that consisted of several small programs (the typical submission was about 16 lines of code). While over 120,000 enrolled only about 10,000 students completed all homework assignments (about 25,000 submitted at least one assignment).
The researchers were interested in figuring out ways to ease the burden of grading the large volume of homework submissions. The premise was that by sufficiently organizing the “space of possible solutions”, instructors would provide feedback to a few submissions, and their feedback could then be propagated to the rest.
