“Figuring It Out” Is Where the Learning Happens

 I often get asked the question when doing webinars, workshops, or professional development training, "is there a quick way to do that" with Sketchpad, TinkerPlots or Fathom? For example, last week we had a webinar on functions, and the question came up about whether Sketchpad had a … Continue Reading ››

ICME: The Nature of Students’ Mathematical Thinking

Like other enthusiasts of mathematics, I’m captivated by the way that mathematical ideas can explain things in the physical world around me, and by the way that I can carry out mathematical thought experiments in my mind and then apply the results to control my external physical environment.

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 ››

Parents, Children, and Functions in Sketchpad

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 ››

Real-World Problems: Whose World Is It, Anyway?

At a meeting of mathematics supervisors this week there was much discussion about how to meet the needs of struggling learners. I thought of the students I’d worked with over twenty years in the classroom, and of how my kids caused me to rethink my teaching. They asked me a lot of surprising questions. Take this … Continue Reading ››

Walk Like a Mathematician
