Two things should make it into LORS additionally to view tracking:
a) Rating. Rating should not only be done by professors on the whole course, but by students taking the class on each item. Make this rating anonymous and the content will be able to improved considerably based on users feedback.
b) Relationships. The relate functionality displayed at dotknow.org will allow you to support multiple paths through the learning object (course). It has the benefit though that *users* can create their own path based on what they read and what connections they are drawing. If users use this actively, a better default structure for the content can be arranged.
