Donna Gaffney, trauma specialist and co-founder of 4 Action Initiative, and MaryEllen Salamone, co-founder of the Families of September 11, explore what teachers have learned from talking to kids about 9/11 for 10 years. They discuss the curriculum they helped develop with other volunteers from Liberty Science Center and the New Jersey Commission on Holocaust Education, titled "Learning from the Challenges of Our Times: Global Security, Terrorism, and 9/11 in the Classroom."
