David B. Spangler- ActiveMath
David B. Spangler has devoted his entire professional career of more than 35 years to mathematics education. He began as a middle-school mathematics teacher where he taught in an individualized setting. Later he taught at Triton Community College where he gained direct experience interacting with struggling students in a developmental math laboratory. Currently he teachers mathematics methods courses through National-Louis University and ActiveMath Workshops, a professional development company that he co-founded in 1994 (www.activemath.com). Some of the methods courses and workshops he facilitates address special needs students, intervention, computation, and error analysis at the elementary level. David has literally worked with thousands of students and teachers during his career.
For many years David has worked as a mathematics textbook editor at the K–12 level for major publishers. He has also authored several mathematics books and has written numerous articles for mathematics journals, such as Mathematics Teaching in the Middle School. Based on his extensive experience in mathematics education, David is uniquely qualified to write this book.
As a mathematics educator, David’s goal has always been to teach mathematics for meaning rather than in a way that promotes rote memorization. This book was written to help teachers achieve that goal. David’s other professional goals include exploring ways to teach mathematics through engaging, real-world applications and to explore humorous aspects to mathematics — especially mathematical blunders that illustrate mathematics illiteracy. David is a frequent speaker at conferences of the National Council of Teachers of Mathematics and other professional organizations where he addresses teaching mathematics for meaning, teaching mathematics through real-world applications, and teaching mathematics through humor. He also delivers after-dinner talks on the subject of mathematical humor.
David lives with his wife, Bonnie, in Northbrook, Illinois. They have three grown children, Ben, Jamie, and Joey.
