Since the publication of the first edition of Online Teaching in K12: Models, Methods, and Best Practices for Teachers and Administrators, education has undergone two seismic shifts: the pivot to online teaching necessitated by the COVID-19 pandemic and the rise of generative artificial intelligence tools for the classroom. This updated second edition takes these developments into account, serving as a hands-on reference for education professionals—teachers, administrators, program managers, policy makers, and faculty in teacher preparation programs—who are seeking success in the planning, design, and teaching of K12 online courses and programs. Twenty-nine experts and practitioners present an array of frameworks, models, and methods; tools and apps; and other need-to-know information on the myriad aspects of online teaching and learning in both fully online and blended environments. Pre-service, new, and experienced education professionals can all use this book to build or supplement their knowledge and skills. The second edition of Online Teaching in K12 is the essential guide to help educators navigate and shape the future of K12 online primary education.
