Is The Term Paper Dead?
Doing away with the term paper is not the answer to plagiarism. The fact is, someone who will turn in work that is not their own is determined not to learn. Test them another way, and they'll still find a way around it. No one can be educated against their will. They can be indoctrinated, but only at the price of creative thought.
Plagiarism is a symptom, not the problem. Tell me how you'll teach students to care, and it won't matter if it's a paper, a test, or a painting they produce; they're the people who will change things in the real world, someday. They'll do what they are inspired to do because someone taught them to think for themselves, and nobody persuaded them otherwise.
