The student should not be punished for a pedagogical disagreement
between teachers. From the information you have given, the student
worked in an open, informed atmoshpere and met the criteria for each
class. Perhaps the teachers should collaborate more before
assignments are made, presenting some that are independent, others
that develop the student's ability to present relevant, complementary
papers that combine research, writing, communication, and revision
skills. In the real world, not everything we do is original and
unfettered; why deny students this learning experience?
