Ken teaches Precalculus and Calculus in an accelerated program at Sisler High School in Winnipeg, Manitoba, Canada. He has been using The Geometer’s Sketchpad since first seeing it at an NCTM conference in 2004. … Continue Reading ››

I had the privilege this year of participating in the CADRE Fellows Program of NSF's Community for Advancing Discovery Research in Education, and met a number of colleagues in the program whose projects, like our Data Games project, are exploring the classroom benefits of computer-game- or simulation-based-learning. (In this post, I’ll refer to technology-oriented … Continue Reading ››

In a recent blog post, Karen Greenhaus describes how it's possible to construct familiar corporate logos using Sketchpad. You might start with a rhombus, for example, and then reflect it twice to … Continue Reading ››

According to a recent Wall Street Journal article, "Big Data’s Problem: Little Talent," the technology industry faces a major dearth of employees with strong data analysis skills. The article quotes a 2011 study by McKinsey:

A significant constraint on realizing value from Big Data will be a shortage of talent, particularly of people with deep expertise … Continue Reading ››

As a student, I didn’t place conic sections on my list of favorite high school topics. The standard textbook treatment of the ellipse, parabola, and hyperbola seemed uninspired. There were messy algebraic equations with multiple square roots. There was lots of terminology. Drawing a conic meant plotting several points on graph paper and connecting them with … Continue Reading ››

At around Pi-hour on Friday afternoon we successfully launched our new website. The night before (the night of the big storm for Bay Area folks), Andres and I were out with a dear former colleague and I mentioned I was going to blog about our new branding, new website, and new name. She said, “You … Continue Reading ››

Functions are hard for students. Students seem to master various families of functions – linear, polynomial, exponential, trigonometric, and so forth. They can graph them, evaluate them, transform them, and answer a variety of questions about them. But ask even our better students a question that’s out of the ordinary and we’re likely to be taken … Continue Reading ››

As a parent and math educator, I'm always on the lookout for high-quality, fun apps that help my sons and other young people develop their understanding of math. There are a large number of math games for mobile devices and PCs being churned out, and many articles being written in popular ed tech blogs and … Continue Reading ››

In a recent blog post, Karen Coe referred to Conrad Wolfram’s opinion that programming is to mathematics what composition is to English. I’ve taught programming and written a lot of Sketchpad code, and I appreciate Wolfram’s analogy. In English class, students read books, poems, short stories, essays, and articles—but to gain a deep appreciation for … Continue Reading ››

As an author of Sketchpad activities, I like to think that I can pose good problems for students to solve. But as I visit elementary classrooms and watch students use Sketchpad, I realize that a large part of the enjoyment they derive from using our software comes from creating their own problems and sharing them … Continue Reading ››
