Acknowledgments

Many authors take pains to recognize the essential contributions of others while reserving all blame for errors or omissions to themselves. I’ll be no different. While 99.9% of the text in this book came from my brain, through my fingers, and onto this here laptop, the book on your screen or in your hands would not have been possible without the support, encouragement, or assistance of many friends, colleagues and students.

Ideas and inspiration for problems and examples used in this book came in some cases from literature, but also from listening to and discussing ideas with colleagues. Whether they know it or not, Mike Weber, John Tyndall, Peter Wolter, Julie Blanchong, Jim Adelman, Cathy McMullen, Lisa Schulte Moore, Sally Carullo, and Adam Janke have all supplied at least a kernel of an idea reflected in these materials.

Financial support for taking the final steps in creation of this book came from a Miller Mini-Grant for Open Educational Resources from Iowa State University’s Library, Office of the Senior Vice President and Provost, and Center for Excellence in Learning and Teaching. I owe a great deal of thanks to Abbey Elder, open access and scholarly communication librarian at Iowa State, who held me accountable for using that grant wisely, managed a blind review process, and helped me navigate the weeds of electronic publishing. In addition to three anonymous reviewers, I am grateful for the editorial assistance of Ellen Justis and Quyn Westfall. Students in the spring 2019 section of NREM 240 at ISU were the first to use a completed draft of this text, and I am grateful to them for their candid feedback. Of those students, I’m particularly grateful to Diane Maxwell for her sharp eye in catching typos and other blunders.
