A newly created course is characterized by its authors as “fast” and “introductory”.
Nevertheless, in practice, students need to spend three times the anticipated time and
effort before they can get an acceptable level of familiarity with the material;
additionally, upon completion, students are capable of solving problems from an
associated repository at all levels of difficulty. It should be clear that selecting this
course purely on the basis of its associated metadata might lead to serious mistakes
(e.g., in the process of content filtering). Adding information from its actual use
provides a more “informed” view of the course and has the potential to lead to better
personalization as a direct consequence.
