A system for providing educational content to a user includes an
audiovisual medium via which presentation(s) included in a course
offering are accessible as audiovisual content and as text content. The
system is selectively promptable by a user via the medium to activate a
plurality of expositions of aspects of the course offering, including
aspects of the presentation(s), in a plurality of different modes of
exposition. This system makes it possible for an individual student to
optimize his/her approach to educational content in order to make use of
the most effective ways in which that student learns.
