Why do some 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 the students–or to the worldwide community of visitors to the OCW Web site. In other cases, the instructors plan to re-use in their classroom the assignments, quizzes, and exams, and so they do not wish to widely publish their solutions.
