Is playing with students before presenting demands the secret to a great work session? We're joined by special guest Dr. Amanda Kelly, Behavior Babe herself, to answer this question with a detailed and in-depth discussion on her presession pairing research.  Not only do you get a behind-the-scenes tour of the research process and overcoming participant pitfalls, but also a heated discussion about whether Katie Perry or Angry Birds is the ultimate reinforcer.  If you learn one thing this week, its stop grabbing things from our learners!
