Why do some UNU OCW course sites lack solutions to assignments, quizzes, and exams?
In some cases, solutions to homework assignments, quizzes, and exams are only discussed and presented in the classroom and not made available in print or electronic format to students, or to the worldwide community of visitors to the UNU OCW Web site. In other cases, the instructors plan to re-use the assignments, quizzes, and exams in their classroom and so they do not wish to widely publish their solutions.
