Ask your friends to tell you about their best teachers. They likely will describe people who were passionate about their fields and student learning, knew their subjects cold, communicated great faith in students’ capabilities and insisted they live up to those expectations, were excellent explainers, and were caring, authentic, respectful, and well prepared for class. For the past 20 years, I have been publishing books and articles about effective teaching approaches; the qualities your friends would name are typical of the best teachers. Poor in-person teaching happens every day at every university.... Poor online teaching also happens every day. But great teaching and deep learning also happen online.
