Session idea: DH-enabled research assignments

I’m interested in discussing a topic that dovetails nicely into sessions that others have proposed: exploring DH-enabled alternatives to the long-form researched argument in undergraduate courses.  In a Spring course (cross-listed as English and Environmental Studies) I’ll be working with my upper-division students on a wiki and a handmade book.  Advice from those who have developed short- or medium-form research assignments using DH tools and platforms would be immensely helpful.
