About Math Without Borders
Author/Producer of the Home Study Companion courses
Allow me to introduce myself. I am David Chandler, author of the Home Study Companion series. I love to teach physics and mathematics!
Education: I have a BS in Physics from Harvey Mudd College (individual program of studies combining physics and engineering), an MA in Education from Claremont Graduate University, and an MS in Mathematics from Cal Poly University.
Teaching Experience: I have taught physics, mathematics, astronomy, and computer programming for over 35 years in public, private, international, and charter schools and community colleges since the early 1970’s. In the last nine years before I retired, I taught at Eleanor Roosevelt Community Learning Center, a K-12 charter school that works with homeschooling families. Working with homeschoolers led me to see the need for course materials that replace the classroom experience. At this point I have taught more students in my retirement than in my regular teaching career.
One of my more interesting projects at Eleanor Roosevelt was designing a mixed grade level course called Math Explorations (for 2nd grade through Jr. high) to stimulate curiosity and encourage mathematical thinking. Math Explorations involved “precursor activities.” I described it as “stuff that doesn’t look like math.” We did puzzles, mazes, perspective drawing, distorted photographs, and a lot of other fun and fascinating things to stimulate curiosity, inventiveness, and a sense of wonder. It’s not about “math skills,” narrowly defined. It’s about how the brain is wired! This is the kind of thing I could do at a charter school working with homeschoolers that I couldn’t possibly get away with in a conventional public school. I took a similar approach for several months as a “math columnist” for the online Schoolhouse Teachers program, except this time at the high school level. A few of my Math Explorations projects are on display under the Bonus Topics tab.
I have frequently put mathematics to work outside the classroom, including working as a programmer, inventor, product designer, and consultant. I really do use math on a daily basis apart from teaching! Mathematics is a wonderful tool that enhances the potential for both creativity and fundamental understanding of the world.
