So, it's done. I've submitted the final draft of my dissertation to my committee and will defend on July 1st. I reworked it a bit more after the last draft, moving my process into the methods chapter and making chapter 4 all about the preliminary results. Then chapter 5 is my new elaborated TPACK model and chapter 6 is the conclusion. I think it's pretty cool, but we'll see in about a week! 

I am now most nervous about the questions my committee might ask me in the defense. I have no idea what to prepare for. I finished my coursework several years ago, so while I understand the concepts from the courses I couldn't necessarily give any specific details about my courses. I also don't know how thoroughly I need to review the literature from my chapter 2 or whether they'll mostly focus on chapter 5. I've asked my chair if he can provide some guidance, so we'll see what he says.
