Even-handed video from Al-Jazeera interviewing some of the people involved in the anti-Value-Added-Model lawsuit against Value-Added Model evalutations of teachers in New York state.
You may have heard of the lawsuit – it was filed by elementary teacher Sherri Lederman and her lawyer, who is also her husband.
