Excercises, randomly generated and automatically checked
I've been authoring excercise questions for students using Maple T.A.. These questions are randomly generated, and answers checked online, which gives immediate feedback to students. Students like this service, but I as an author was severely annoyed by the workflow, and thought that it should be possible to achieve something better using Sage.
Is there any project underway which attempts to use Sage to generate questions and check answers in a web-based setup? If so, how mature is it?
