Furman Brown has spent over a decade figuring out how to design a better school. As a first-year teacher in South Central Los Angeles in the early 1990s, he got a taste of what was wrong with the traditional public school model: It was not designed to serve students "or" teachers well. Convinced there was a better way to organize and distribute work inside schools, Brown joined the staff of a start-up school in Brooklyn, New York, and slowly, over the years, pieced together the sides of what he calls the "Rubik's Cube" of school design. With his Generation Schools model and its pilot, Brooklyn Generation public high school, which opened in 2007, he thinks he may have solved it. Instead of isolating teachers, the Generation Schools model organizes them into grade- and subject-based teams, designed to blend different types of expertise and levels of experience. Generation Schools is just one model, and today, it is determining the outcomes of only one high school. But its design and the principles that it rests on--using people strategically and time intentionally--represent a new way of thinking about how to approach the teacher quality challenge in public education.
