Rethinking Student Transitions: How Community, Participation, and Becoming Can Help Higher Education Deliver on its Promise, presents a reimagined theory of student transitions in college. The authors contend that while previous theorizations have helped move the practice of supporting student successforward through the latter half of the twentieth century, earlier conceptualizations and models have led to an inconsistent and incomplete picture of students' experiences in transition. The book offers both a review and critique of current models of transition and then develops a new conceptual viewpoint based in the ideas of situated learning and transitions as becoming. The second half of the book is dedicated to using this newtheoretical perspective to illustrate how higher education professionals can create conditions to support students in transition more intentionally, with a particular view toward supporting historically marginalized students, including racially and ethnically minoritized students, first-generation students, and post-traditional students.
