“skilled” = fully indoctrinated
“skilled” used to mean well educated in the subject matter and able to successfully convey the material to the students.
But, that was back when the subject matter dealt with reality.
With an excellent undergraduate program, those with potential will be identified and prepared for the classroom. To thrive, they need discipline support and a stable environment.
All of this extra training is based on the myth that anyone can be a teacher if they get enough training. Too much training does harm....it wastes time capable teachers could spend teaching and it artificially boosts those who shouldn't be teaching.
