I was an instructor in the US Nuclear Navy, teaching high school and college grads how to operate a naval nuclear power plant.
6 months of high intensity 8-4 pm classroom instruction, with studying from 4 to midnight and 6 - 8 am; Followed by 6 months of "prototype" training operating a land based nuclear power plant under instruction on swings-mids-days shiftwork. The prototype training was "Competency Based" in a student learning environment (self learning required systems) in a one-on-one instructor checkout signing of a qual card (equivalent to "badges").
I didn't learn educational theories... I taught how i was instructed when i went thru the program initially. I wasn't introduced to "Bloom's Taxonomy" until two years ago at Idaho State.
Military training is different from Post Secondary education... but it seems post secondary is trying to catch up to military competency based training.
