Presents a sociological perspective on the issues involved in transforming the structure of inner city schools. This book evaluates the models which have guided past and present attempts at educational reform, and proposes a coherent theory for attacking the problems of urban education. Dr. Janowitz examines the inner city school as a social system—the physical structure, community setting, people involved, and persistent patterns of behavior. He analyzes the current trend of specialization teaching and recommends instead an "aggregation" model which increases the scope of the individual teacher and restructures the climate of the school.
