Constant Velocity Card Sort

Autumn is here one day then gone the next on campus. We’ve had this odd up/down temperature fluctuation this week, which has made for many foggy days. Monday, as I walked home, I was struck by the fog rolling in over the nearby hill and enjoyed a high of 58°F. Today, it’s 80°F and sunny. Oh, and by the way, that building on the right is the dorm where I live.

Ok, that’s enough rambling about autumn in the Pioneer Valley. Let’s look at some physics.

My colleagues and I created a card sort for our students and the results were wonderful. The students have been working with five different representations at this point and our card sort left out only the data table. Here’s one page from the sort:

While sorting today, students chose to work together in so many different ways. My favorite was this group that turned their sort into a kind of Go Fish game — each kid took all the cards for one representation and read off important details to ask for that card from the others. For instance, “do you have one with a velocity of +6 m/s and a starting point of -3 m?”

Many thanks to Kelly O’Shea and Brian Frank for sharing so many card sorts over the summer. Their work inspired us to create our own.

If you use and improve ours, would you let me know? Constant velocity card sort (on Google Slides).
