"Davis Guggenheim, the director of An Inconvenient Truth and Waiting for Superman, has a new film coming out —Teach, a two-hour documentary premiering Sept. 6 on CBS. The film follows four public school teachers throughout the school year, including Joel Laguna, a 10th grade AP World History teacher at Garfield High School in Los Angeles Unified. “This was an attempt to show what a really effective teacher is,” says Guggenheim. “If we could understand that, maybe we could get more of them in the classroom.” "
