But they are learning to practice, at least in some of the courses (others are focused on much-needed theory). It's like forcing students to write code by hand because using an editor would give away too much. And I know first-hand that CS education used to do precisely this as I have proctored such exams myself. What needs a rethink is how education, especially CS education, is imparted given the existence of these tools.
