Written specifically for academic librarians and library administrators, this book identifies the myriad benefits of peer-assisted learning, exploring how the implementation of peer-assisted learning benefits information literacy instruction, cocurricular outreach, and reference services.In this era of accountability—and stretched budgets—in higher education, librarians need to make instructional programming both highly effective and sustainable. Peer-assisted learning is a methodology that has long been accepted in teaching but is relatively new as applied to academic library instruction, outreach, and reference. This book brings together the most innovative applications of peer-assisted learning in these contexts, explaining specific ways to apply peer-assisted learning in a variety of academic library settings for maximum benefit.This guidebook begins with an extensive literature review of the theoretical underpinnings of peer-assisted learning and the various benefits these programs can provide academic librarians and peer mentors. The bulk of the book's content is organized into three sections that address the subjects of information literacy instruction, cocurricular outreach, and reference services separately. Each section showcases real-world examples of peer-assisted learning at a variety of academic institutions. Through these case studies, readers can fully understand the development, implementation, and assessment of a peer-assisted learning program, and librarians and administrators will see the practical benefits of enriching the experiences of student employees. Practitioners will receive inspiration and guidance through chapters that discuss training activities, identify lessons learned, and explain the implications for further research.
