In this program, Dr. Greene interviews Dr. Craig Murphy, school psychologist in the Newton, Massachusetts Public School system. As part of a 3-year, federally-funded project overseen by Dr. Murphy, many of the elementary schools in Newton have been implementing the Collaborative Problem Solving approach. Dr. Murphy describes the challenges and successes in helping classroom teachers understand challenging behavior as a form of developmental delay and embrace Plan B as a viable option for helping students with social, emotional, and behavioral challenges.
