Fans of the popular teaching blog Faculty Focus or The Teaching Professor newsletter will recognize Maryellen Weimer, long-time author and professor emerita at Penn State Berks.Active Learning: A Practical Guide for College Faculty is a collection of two to three-page articles, most of them published previously, discussing proven methods for building and maintaining active learning in the classroom. Each piece is straight to the point and feels like the kind of conversation you would have with your colleague down the hall. Written by and for faculty, Weimer brings together Claire Howell Major, Rob Kelly, Elizabeth Barkley, and others to share their expertise in three areas: leading effective discussions, selecting low-stakes assessments and learning activities, and managing group work.There are also a few tools and templates that both experienced and novice users will appreciate, and lots of references. Although this slim volume is a bit pricey, you’ll refer to it often and others will want to borrow it. Don’t let them, or you might need to purchase a second copy after loaning your creased and dog-eared one to someone and never getting it back. Also available on Kindle.
