modified and used over many different semesters with students. Parts of these ideas can
be found throughout this text. In addition, Will Dickinson and Steve Schlicker provided
me access to a large number of their electronic notes and activities from teaching of
differential and integral calculus, and those ideas and materials have similarly impacted
my work and writing in positive ways, with some of their problems and approaches finding
parallel presentation here.
Shelly Smith of GVSU and Matt Delong of Taylor University both provided extensive
comments on the first few chapters of early drafts, feedback that was immensely helpful
in improving the text. As more and more people use the text, I am grateful to everyone
who reads, edits, and uses this book, and hence contributes to its improvement through
ongoing discussion.
Finally, I am grateful for all that my students have taught me over the years. Their
responses and feedback have helped to shape me as a teacher, and I appreciate their
willingness to wholeheartedly engage in the activities and approaches I’ve tried in class,
to let me know how those affect their learning, and to help me learn and grow as an
instructor. Most recently, they’ve provided useful editorial feedback on an early version of
this text.
Any and all remaining errors or inconsistencies are mine. I will gladly take reader and
user feedback to correct them, along with other suggestions to improve the text.
