Desc: Blackboard Bubble: Directed by Jeff Deutchman. In 2001, I graduated from a NYC private school. Four years later, I went back in order to ask my teachers some serious questions. In this probing existential documentary, NYC teachers extol the egalitarian virtues of public education, and then attempt to justify their choice to teach at private schools. Are private school teachers more part of the problem or more part of the solution?
