In an econometrics class in college, we have a team project and a final exam. The exam contained a question specific to the analysis method used in the team project. Answers to this question identified who genuinely worked on the project and who coasted on their team's work. Same thing can happen here: students can submit their term papers, but they have to do a 5-minute oral exam with an instructor or TA to discuss their paper.
