Preparing for the next step

I am finding myself moments away from my first days as a teacher. It's really amazing to think that my life's work as a student is finally culminating. I am going to step into my classroom on Monday as Ms. Raskin, apparently an alter-ego in itself. I can't wait, but find myself terrified at the fact that I am going to make a difference in someone else's life--or worse, have no impact at all. I've been trying, over the past few days, to put together a unit on a book set during the Iranian Revolution. I love the book, yet continually am finding it difficult to find out what I really want my students to take away. I've flirted with the middle eastern experience, and having very little understanding of it myself am becoming increasingly frustrated. It's so exciting to continue learning, but feels like a let down to find that there's very little for me to stand on...
