The second edition of Student Development in College will help student affairs practitioners understand the developmental challenges facing today's college students. It will provide scholars with a comprehensive and inclusive overview of the most important student development theories and related research, including new approaches with which they may not be familiar, particularly related to social identity development. Most importantly, it will assist student affairs professionals in designing individual, group, and institutional approaches to work more effectively with students at various developmental levels and to facilitate student growth. This second edition includes the "foundational theories" of student development found in the first edition, but also offers newer integrative social identity theories that look at student development in a more holistic way. These theories are critical for understanding the diverse student populations of the twenty-first century.
