I have a B.S. in Liberal Arts (concentration in Managment and History) from Excelsior using the information from this forum (non traditional). I am a controls engineer but would like to substitute teach in Michigan during my retirement. Maybe even be a regular teacher. Not sure. I have heard of a certification program called teachers of tomorrow. Also considering a Masters degree from WGU in education. What you all think? Would like to teach science, computers, social studies, and business. Don't really have a preference for a particular age group.
