I'm thinking about going back to school to get my secondary biology teaching certificate. I've never taught anything in my whole life, so to get a feel for whether teaching is really something I'd like to do, I asked if I could shadow a middle school science teacher. The board of education said that I wouldn't be able to shadow someone, but I could substitute teach. Is it just me, or is that putting the cart before the horse? I've NEVER taught anything, and they want me to get a feel for it by subbing? How can I substitute teach if I don't know what I'm doing? My question to all of you is, should I go ahead and sub, even though I don't know how to teach? Thanks for your opinions!
