They are experiencing something very different from the traditional factory model of American education, in which everyone on the assembly line is delivered the same standardized units of information (lectures and textbooks) and then must pass the same quality inspection objective exams.

It has, however, been proven to be a convenient way for colleges to record on transcripts that a standard body of knowledge has been duly delivered.
