The conference room was packed at 5pm on a Saturday afternoon as I prepared to give a public talk and workshop at the 2016 NSTA conference in Nashville, TN, on how I use enhanced exit tickets in my science classroom to increase student accountability. What surprised me most was how awake and engaged the participants were after a long week of conferencing. We reviewed what an effective exit ticket looks like, and we explored the kind of evidence it generates and how to use that information to be more responsive to student needs. Participants also created their own enhanced exit tickets to take back to their classrooms. I left energized and ready to share this amazing evidence-based teaching strategy with others.
