Flip It! is a resource that methodically guides teachers as they take steps to begin flipping their ESL classroom. Flipped learning exposes students to the instruction outside the classroom and uses class time to apply new knowledge through activities, typically with the teacher in the “guide on the side,” as opposed to the “sage on the stage,” role. Robyn Brinks Lockwood introduces flipped learning and compares it to blended and mixed–mode learning. She then documents the many benefits of flipping for her and her students—improved student performance, lower absenteeism, increased interaction, and more time for students and teachers for what they need, among others. Flip It! is the perfect introduction to flipping ESL lessons because it shows teachers how to flip without making videos and without giving up on a textbook, how to take advantage of readily available additional material on course content, and how to modify a variety of activities to work in a flipped learning environment. More than 50 activities from textbooks are included to help illustrate ways to flip various reading, writing, listening, speaking, grammar, and vocabulary lessons.
