One of my favorite "projects" is in my Pathology class. It always falls around Halloween and I allow my students to choose a pathological condition to do an oral presentation on, but the representation muct be a food item, after which we all get to EAT.... love those sebaceous cysts cream cheese danishes. I don't assign the "condition" or the food item. It is the most popular assignment in the massage program at the college I teach and after taking this course I believe the autonomy of the assignment enhances it's success.
