I started my career in the US Navy Nuclear Power program. At that time, there was initial insturction for Machinist Mates, Electrican Mates, and Instrument Techs... then combined instruction in Nuclear Power School - claimed to be the third toughest school in the nation at the time. This was "traditional" classroom instruction (well, crammed into 8 hours a day, 7 am to 4 pm, 5 days a week) with studying from 4 pm to midnight and 5 am to 7 am...
Then we transitioned to 6 months Nuclear Prototype at one of three locations (NY, CT, ID) and a handful of prototypes. These were full scale nuclear plants with propulsion systems and electrical plants (but not full scale ships). Instruction at protoype was more like a "flipped classroom". Students got a "qual card" which required instructor signatures to ensure adequate knowledge, and watchstanding proficiency. System knowledge, system interrelations, casulty response... with mid term, final exam and 3 person oral board (3 instructors to one student). Schedule was 12 hour days- rotating shift 7 on swings, 1 off, 7 on mids, 2 off, 7 on days, 4 off.
The qual card is what drove learning and requirements.
Learning from military and how they train personel, to either fly jets, operate nuclear power plants, operate tanks and artillery, or a basic rifle can be beneficial for CTE.
CTE is similar, but is not the same...
With CTE, i can go home to my bed every night, and no one else "relies upon me" when they are in their bed, and i am on watch....
