I have an M.S. degree in electrical engineering from Univ. of Minn. and have been a practicing engineer for almost 30 years now. I've about had my fill of engineering and I'm seriously considering switching career to teaching high school physics and math. Assuming for the moment I have sufficient mastery of the material at the H.S. level, I have a few questions: - How common is it for engineers to switch to teaching high school physics or other science? - Can it be done without getting a degree in physics? (I understand I may need to get a degree in education, or some other flavor of certification. - Setting aside the 70% pay cut, how difficult is the transition? - How difficult is the job? - Is it expected that there will still be a shortage of H.S physics and math teachers in three or four years? Thanks for any insight you can offer.
