Yes, anything can be 'taught' if the person has an interest. IMHO, the best method is "hands-on" along with class time.
I had a few "youngsters" over the years that worked with/for me, and those that had an interest to learn, did well. Back then we worked at a printing plant, and there was a varied amount of TS from VFD's to old DC equipment. Experience is a great instructor.
Reading from books, and doing class work is a valuable instructional tool, but having actual 'hands-on' makes it even better. Actually 'seeing' a piece of equipment, after looking at the schematic, presents a "real life" experience.
