Teachers—Walk a Mile in their Classroom

I was lucky enough this past week to visit some classrooms and see teachers using Sketchpad in various ways. It's been seven years since I was in the classroom myself, so for me it was like coming home. It brought back a lot of great memories, though also some reminders … Continue Reading ››

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 ››

Understanding Proportional Relationships with the Proximity Data Game

In the Fall as Middle School and Algebra 1 teachers look for activities to develop students’ understandings of proportional relationships, they may turn to measuring scale diagrams or using springs. One of KCP Technologies' new online Data Games called Proximity offers a new option for teachers to help students learn about proportional … Continue Reading ››

Monopoly Math

Scan the headlines and you’ll see a stream of stories about educational technology: 1 to 1 iPads, teacher blogs, the flipped classroom… the electronic beat goes on. I’m not pining for the silky feel of chalk on my fingertips, but there’s something to be said for old school games and their ability to illustrate mathematical … Continue Reading ››

The Standards Are Not The Curriculum

We were so impressed by Jamila Riser's talk at NCSM a couple of years ago that we asked her to present an Ignite! for us this year. Now, we've asked her to guest blog so we can share even more about the amazing work she's doing in Delaware. Jamila is the Director of the Delaware … Continue Reading ››

She's done a variety of work for Key, including presenting webinars, moderating online courses, and … 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 ››

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 ››

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 ››
