"To enhance the learning experience of a term paper, students were required to publish their papers in Wikipedia. Publishing for a large audience provided authentic feedback and encouraged students to do their best work. Using Wikipedia also allowed students to connect with a vibrant community and share their knowledge by making their papers publicly accessible."
I haven't watched the profession, but the sentence "students were required to publish their papers in Wikipedia" makes me cringe. One can only hope the professors introduced them to (or understood) the norms and policies of the site, and didn't require original research...
