Early and mid-adolescence is a critical stage in the life course. Urban adolescents face special risks and often have fewer supports and opportunities to guide them through this critical period. As the United States population becomes increasingly diverse, particularly in urban areas, families, communities, and schools may need to create new social institutions and relationships to meet the needs of this new population. This course focuses on three central questions. First, how are the education and developmental trajectories of adolescents shaped by their experiences in their families, schools, and communities as well as the interrelationships among these domains? Second, what are the special needs or issues that arise for adolescents who are from immigrant families, who are cultural, racial, or ethnic minorities, or who are from educationally and economically disadvantaged households? And third, how do we translate an understanding of the needs of adolescents and the conditions in families, communities, and schools that foster positive development into the design of policies and practice?
