Maybe you're an undergraduate or graduate student who's just been appointed a TA. Or maybe you're a postdoctoral student or a new hire with limited teaching experience. In either case, you'll be expected -- with little to no training -- to enhance the learning experience of students. Kathy Nomme and Carol Pollock recognize this gap between expectations and training and draw on decades of experience to offer practical advice on: (1) interacting with course instructors or coordinators; (2) dealing with nerves and anxiety; (3) preparing the first session; (4) supporting student learning; (5) developing learning exercises; (6) engaging students with diverse needs and backgrounds; (7) using technology in the classroom; and (8) assessing student work and providing feedback. This short, accessible guide can be applied to any discipline or teaching scenario -- from large lecture halls to smaller labs, studios, seminars, and tutorials. It not only demystifies expectations for TAs, it sets the stage for developing a lifelong teaching practice. This book is a must-read for current and future TAs, postdocs and new faculty with limited teaching experience, or anyone involved in TA or teacher training.
