Hi Gary
First, Carol Twigg points out that the "credit-hour" is a relic does not, in any way support the need to keep using the antique. The fact that the term "hour" in credit-hour is in the name does not rationalize keeping the term with "hour" lopped off. The idea of a "common currency" is also questionable. When Harvard was asked to submit to the regional accrediting agencies for their approval, it said that the agencies were free to visit the campus but that Harvard would not go through the standard drill.
In mathematics, in the area of "group theory" one can reduce a large matrix to a one dimensional representation in order to achieve simplification and ease of manipulation. Many years ago we used observation which then was reduced to mathematical representations and thence to simulations until the models became the reality.
The credit or credit-hour is such a reductive representation that students, faculty and even institutions cast a blind eye because having to face the facts would throw the system in disarray.
There is a wonderful book called The Spacechild's Mother Goose. In it is a poem which goes something like this: This is the theory that Jack built. This is the flaw that lay in the theory that Jack built. This is the constant K hiding the flaw....This is the mummery-jummery justifying the K...this is........ At any rate, the theory finally collapses in the end.
The credit or credit-hour discussion is on-going because most realize that it is seriously flawed. Some seek another "fix" to avoid collapse while others seek an alternative theory, one more congruent with reality.
The suggestion to start this discussion was, in my opinion, not to try to find a "fix" to the false measure but to seriously engage with alternatives. Since this is a group which can have a number of questions or subjects under discussion. It is possible to have parallel issues. I would suggest that those who want to take the "blue pill" and try to maintain the credit/credit-hour create a topic in this group and those who have swallowed the red pill and gone down the rabbit hole continue the current thread.
