Acknowledgements

We gratefully acknowledge the wonderful assistance from several students from the Instructional Psychology and Technology department at Brigham Young University who assisted in publishing this book. Megan Charlton and Halli Romero provided outstanding copyediting of the chapters, and Rebecca Nissen was the lead instructional designer and project manager (and also assisted with copyediting). Rebecca also created the wonderful cover for this book, which represents the tree metaphor that we used for orienting our thinking on this edition. The contribution of all of these collaborators were professional, timely, and made the book far better. 

We are also deeply grateful to the authors willing to publish their ideas in an open format. It is because of you that students, practitioners, and scholars can have access to these ideas. 

Because this book is published online through EdTechBooks, we can continue to make edits and revisions. Please email one of the editors if you see something that needs to be addressed. Thank you for supporting open scholarship!
