You have included some great information. However, I have to show my ignorance and ask what an SOW is. I am a first year teacher and don't know that I have came across that acronym yet, though there are so many I might have and just forgot to be honest.
Also, something I might add that many may not think of is to be aware of words that are actually derogatory and may not seem so, as well as being cautious or avoid altogether using colloquialisms and sarcasm in the classroom. You touched on those when you mentioned becoming educated and making the classroom open and safe for all, but I thought specifically those might helpful for others.
