A Swan Song for Sweet Karen Coe

Today I leave for my first proper vacation in a year and a half. Last time I took such a vacation, Key sold its high school textbooks to Kendall Hunt and transformed from a publishing company to a educational technology company. This time I just hope to survive the end of the world. 🙂 Before … Continue Reading ››

California Dreaming: Reflections on the ISTE Conference

If you're the kind of teacher I was, you may never have heard of ISTE—the International Society for Technology in Education. I'd never heard of them either. Every year, ISTE puts on a very large, well-organized, and international gathering of teachers, techies, and marketeers in a gadget, … Continue Reading ››

Sketchpad Activities, Cognitive Demand, and Differentiation

Not long ago, I conducted a Saturday morning PD session for some Texas teachers participating in an NSF research project. (The research is a controlled study of the relationship between students’ use of Sketchpad and their conjecturing and proving behavior. I hope we’ll have a blog post about this study itself before too long.) Because of the … Continue Reading ››

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 ››

What do you wonder? Real-world math problems are everywhere

We hear this everywhere - students should be doing "real-world" math and they should be applying what they learn in math to "real-world situations." Textbooks and math resources advertise their "real-world problem solving" experiences and "real-life math applications." But, as those of us who are math teachers can attest, often times the real-world examples are … Continue Reading ››

Writing Mathematics with Sketchpad

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 ››
