A NOTE FROM THE AUTHOR
have over 30 years of experience teaching high school mathematics, over
years with animation. I have taught all levels and topics within
the mathematics curriculum for grades 8 through 12, as well as various
computer science courses. For over two decades, two courses never were
omitted from my teaching schedule – AP Calculus and Geometry.
Early on, I began to understand one of the reasons many students struggled with advanced mathematics. They did not see the ideas as dynamic, flowing and connected. Instead, they saw discrete images in which each problem was entirely different from every other one.
Their mental images were rigid and needlessly numerous. Then in the early
1990s, I began to augment my teaching with Geometer’s Sketchpad animations. Beginning just with
geometry, I quickly expanded
their use to calculus and algebra as I witnessed the dramatic and
powerful effect they had on my students’ conceptual development. The
animations graphically demonstrate how many seemingly different problems
could merely be slight variations of a single theme (or concept). My
students did not become dependent upon the computer animations; instead,
they were empowered to create their own mental images that adapt to
varying parameters and grow from one situation to the next.
I am pleased to offer these animations for use in classrooms everywhere.
What has taken me thousands of hours over many years to develop is
immediately ready to use with your students. Just launch Geometer's Sketchpad
and open any of my finished animations. I am
confident that you, too, will enjoy marked improvement in your students’
conceptual understanding, visualization skills, and enthusiasm, just as
I have with my own students.
