Funded by the Association of College & Research Libraries through a 2018 Academic Library Impact Research Grant, the Activating Library Classrooms: Evaluating Formal Learning Spaces for Active Learning and Student Engagement project endeavored to evaluate the design and use of formal learning spaces situated within Penn State University Libraries. Researchers evaluated seven library classrooms and interviewed seven faculty collaborators at six Penn State University campuses in order to identify areas of strength and growth for formal learning spaces. The results affirm the significance of formal learning spaces in libraries and how they can demonstrate academic libraries' abilities to partner in university curricula and student success.
