My BS Education degree is in workforce education, IE instructing your job specialty. There are a lot of good electricans but few good electricians/instructors.
My degree helps me relate to the adult learner, and I understand the learning process, how to build exams, and much more.
What I didn't get much of is how to manage the classroom environment. I am always thinking of how to present material in a unique way
Of course, on the job experience is a must. Don't think I am a classroom only guy. Today I was out in a vault wiring a magnet flowmeter.
Look for some specialty certificates in instructing, and get any certifications for your job speciality. I am certified as a traffic signal tech, control system tech, water distribution manager, and a master electrician.
