Teach For America is a national corps of outstanding recent college graduates who commit to teach in our nation's public schools for two years. Earlier this year we talked with two Teach for America corps members, Donique Nobles and Shelby Rohrer, just as they were beginning their first week in a real classroom in Memphis City Schools. This week we visit them again to get a firsthand report on how tough the challenge being a first year teacher really is.

Also we'll find out about a remarkable emergency medical transport system that is saving lives and preparing for disaster in Birmingham, Alabama. Joe Acker is executive director of the Birmingham Regional Emergency Medical Services System and he's here to tell us more about this innovative program.

We're reaching out to our students and fellow citizens, this week on Smart City.
