The legacy of Brazil's revolutionary literacy campaign

In 1963, the Brazilian government launched a literacy campaign spearheaded by the revolutionary educator, Paulo Freire. The campaign focused on rural communities in the country's north, and used experimental techniques to teach hundreds of students to read through a 40-hour course. A new documentary, "Reading the World," looks back at the history of that campaign through interviews with students who graduated from that program. Host Marco Werman speaks to co-director Catherine Murphy about the film.
