Yes, I had made arrangements to go to #ghc2012. I had paid an Early Bird Registration, booked a hotel and flight, and even made reservations with Super Shuttle. Had been discussing it with our Associate Principal with Instruction.
However, I didn't realize that our approval process on Staff Development had changed and I was asking the wrong person permission to go.
BUT the real reason.
I've ended up with a much bigger course load than I had expected. In fact, I had expected an easier year. We have a lot more students at our school that we expected and the technology electives are down a teacher. That means I have a lot more students than I have ever had.
It also means that my students are at a lower level and less independent. I just finished making a movie over an assignment for my AP students. If they had been my PreAP students they would have knocked out that assignment in about 5 minutes, and gotten it right. Okay, maybe a whole class period.
I left one class early by 30 minutes for a doctor's appointment and no work got turned in. I can't imagine what chaos will happen if I am goine for 4 days.
