The goal of this book is to help educators teach effective live online sessions using Zoom. It offers practical pedagogical advice. The book is based on the author's experience teaching online, observations of several colleagues teaching online at Harvard University, research-based principles of effective teaching and learning, and, perhaps just as importantly, interviews with dozens of students who recently experienced online learning for the first time and also had to adapt to this way of learning in a hurry. -- adapted from page 4 of cover.
