I have been the beneficiary of an all-expense paid PD opportunity. It was taught by professors from 5 different colleges who were working with a NSF grant to teach computer programming. They provided lodging (hotel) and food as well as travel money. This eliminated a HUGE obstacle to trying new things when school is not in session. That brings me to the second part, which is when we have time for professional development. Summer is usually the only time, but we can be creative about finding ways to keep our fires burning back in the classroom to step out and get our own creativity ignited by someone else. I'd love to see more opportunities like this. I wish more colleges and companies (Adobe, AutoDesk, etc.) were able to offer more learning ops. I, for one, could really get into an Adobe Creative Suite extravaganza, but I will never be able to afford Adobe MAX on a teacher's salary.
