Jan,
Thank YOU for the feeback. To be clear, I think extra assignments are a wonderful way for students to express their comprehension, creativity, and benefits associated with a particular topic. I would encourage it. It's the awarding of credit portion that poses some difficulty. My syllabus states no extra credit. But over the years, I've had students ask if they could do something extra (not for credit). Of course I agreed, and gave them class time to present, discuss, and display their project. Sometimes, recognition for a job well done is the most valuable "credit" we can give.
