Exit Tickets and Personalized Project Work

I have been challenged by helping students use time well when working with project based learning (PBL) this year. One of the strategies I use is an exit ticket -- something that is shared that shows progress, accountability, and the state of work before one leaves the class. I came across this post this morning on some tools that may be used for creating exit tickets:

Lots of formal and informal checkpoints are needed with projects in order to maintain accountability and momentum on work. Exit tickets are yet another conversation point for this accountability and momentum.
