Picturing Functions and Functions of Pictures

I’m excited to be making my first presentation of the 2013-14 school year next week in Baltimore. Daniel Scher and I are presenting Picturing Functions and Functions of Pictures. We'll be discussing the connections between pictures and functions. These connections are even richer than I realized when I first began to work with pictures in Sketchpad. In the … Continue Reading ››

Collaborating on an Extension to a Little-Known Theorem

[Today's post is from Steven Fuchs, with whom I recently corresponded and whose enthusiasm was sufficiently infectious that I pressed him to share it here. --Scott]

One day late last spring, while teaching at St. Thomas High School in Houston, I noticed in a book a figure demonstrating Monge’s Theorem. (Don't look this up … Continue Reading ››

Introducing the Dynamic Number Project

Four years ago, my colleague Scott Steketee and I began brainstorming new Sketchpad activities for a National Science Foundation grant called Dynamic Number. Our goal was to use Sketchpad to make ideas from number, operation, early algebra, and algebra come alive through interactive models that emphasized conceptual understanding. Dynamic NumberContinue Reading ››

Revisiting a Childhood Addition Code with Sketchpad

As a fourth-grader in 1977, I had a love-hate relationship with my Addison-Wesley textbook. Its contents overflowed with arithmetic problems, but every so often an entertaining brainteaser appeared to break the monotony of drill practice. These puzzles were clearly marked: Each appeared in a box set aside from the main text and featured a bespectacled … Continue Reading ››

What’s the Appropriate Role for the Teacher when using Computer Games?

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 ››

Preparing Tomorrow’s Data Scientists Through Data Games

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 ››
