For the last 12 years, Amy Schlein Kaufman has taught preschool at Philadelphia’s Lowell Elementary School.

The district says it’s making progress. In this America Tonight excerpt, Lisa Fletcher talks to her and to an environmental scientist documenting the conditions of Philadelphia classrooms who says there’s a cheaper and faster way to fix the city’s problems.
