We’re spending the next two weeks in the company of high school students who are visiting the Museum of Tolerance in Los Angeles. If you haven’t been there yet, it is an amazing interactive museum devoted to issues of hate, from the Holocaust to cyberbullying, and the personal decision-making of the individual to make the world a better place. The challenge is making this trip extend beyond a single experience. The History teacher has all his students writing a letter to themselves and dated one year from today. They’re describing the three personal commitments they made and how it resulted in a better situation. He’ll return the letters to them on January 7. 2011.It brings to mind a question we’re often faced with: how do you make the learning from a field trip endure beyond a single day?
