Professional development that allows time for sharing, reflection and collaboration at a time that is free from other obligations so I can actually be engaged. When I worked in industry we were allowed 20% of our time to work on "new" projects of our own design. The creativity and freedom was refreshing! When I started teaching 35 years ago, I remember LOVING the PD days at the start of school. There was a motivational speaker who got us all jazzed up but THEN we were given the rest of the day and the next day to work on how to implement what we had heard. I loved being given the space and time to create with others rather than doing it at night, alone.
