So this week, for one of our projects, to get follow up data from teachers and kids (never an easy task); we tried a new data collection technique -- data palooza (named by Jenn):

3 days, 3 data collectors, 10 schools, 600+ kids, 20+ teachers, 20+ $25 gift cards and 48 dozen home made chocolate chip cookies. It worked! The teachers liked the gift cards, the kids loved the cookies and we got lots of data from every school. I'm going to do it again even though 48 dozen cookies is a lot of cookies (I made 27 dozen, Jenn 21).
