…is breaking down. This, I think, is the key point:

The conventions of the credit hour, the semester and the academic year were formalized in the early 1900s. Time forms the template for designing college programs, accrediting them and — crucially — funding them using federal student aid.

But in 2013, for the first time, the Department of Education took steps to loosen the rules.

The new idea: Allow institutions to get student-aid funding by creating programs that directly measure learning, not time. Students can move at their own pace. The school certifies — measures — what they know and are able to do.

The public-school paradigm is also based on a century-old model: industrial learning. Time to abandon it, but it’s hard, because it so benefits the status quo, even if it’s a disaster for the kids.
