Term describing the gradual loss of participants in any given course. If a course continues for a long enough time it will loose all of its participants. It is used to explain why there are less course participants from one day to another when there is no apparent reason for it.
The word has also been used to describe the tendency for some courses to become less organized(chaotic) as time passes.
Last weeks programming course had a high degree of course entropy. It was really good, but in the end there was only me and two other participants.
