Well-planned online teaching is a highly creative, engaging endeavor that involves much more than learning to use certain tools and programs, and choosing online instruction for a school or district is very different from rushing to remote learning during an emergency. In this comprehensive guide for K-12 administrators and teachers, Stephanie L. Moore and Michael K. Barbour provide a decision-making process educators can use to make informed, strategic choices about whether and how to incorporate online learning that is best suited to their specific contexts and student needs, including the "handshakes" required to align instructional concerns with school- or district-level infrastructure and supports. As they persuasively argue, online learning is an important feature of a robust educational portfolio and a precious source of flexibility and resilience for schools now and going forward.
