This Reader is intended to serve as a resource of primary source literature on college student development theory and as a text for courses on student development theory. Graduate students and other users are introduced to key student development theories by reading original works of the theorists, developing an awareness of the context in which development occurs, and examining applications of theory to practice. The Reader will also be useful in on-going professional development efforts for student affairs practitioners who lack formal study of student development theory or who wish to become familiar with more recent work on the topic. Those who work with college students and want to create programs and services to promote their learning, growth, and development will find a wealth of resources here to aid in those efforts.
