College of Arts and Sciences

Growing up, every Tom Cruise character was that super-confident, super-cool guy that could bluff his way through any situation with quick wit and a smile. Who didn’t want to be Joel Goodson or Brian Flanagan or Maverick?

But I definitely also had an appreciation for people who planned every move with military precision. Who could see the downstream consequences to actions that everybody else missed. See: Jane Craig in Broadcast News. So: going by the book, or flying by the seat of our pants? Painting by numbers, or just making some happy little trees?

Is teaching an art, or a science? If you’ve been around the game for awhile, you’ve probably concluded it’s both.

Joshua Eyler of Rice University turns the question on its head in a 2015 blog post, proposing that “the most effective teaching is that which helps students learn to the greatest extent possible”.

So how might we change the art vs. science question to reflect this positioning of learning?  Though we’ll have to sacrifice the nicely compact nature of the original, a new version of this question might ask whether achieving a deep understanding of how our students learn (both in general and about our fields) is more of an art or a science.

The sorts of collaborations with students that might reveal this knowledge could certainly be called creative and even artistic.  I also think there is something of an art to being attuned to students’ individual approaches to learning (or their Zones of Proximal Development) and adjusting our strategies and techniques accordingly in order to ensure we are helping as many students as possible.

What about science?  I have to admit I’m biased here.  As someone who is writing a book on the science of learning, I lean more heavily in this direction.  Because learning has its basis in the neurobiological mechanisms of the body, I think science has much to teach us about learning.  Learning is also rooted in the social world as well, so the fields of sociology and psychology provide further opportunities for understanding.

Brain science and psychology and making adjustments on the fly for what our students (collectively or individually) need at the moment? Yeah, that sounds exactly like what teaching is. “All Of The Above”.

That was us a couple of weeks ago. I know the look I saw on my kids’ faces after the logs quiz. It’s never a good sign, but that “I don’t get this and math is stupid and I quit” feeling in February makes for a long last 13 weeks for everybody involved.

So I called an audible.

I’m hardly the first to roll out this activity. My favorite instructional coach was doing Barbie Bungee before I was even teaching, long before Twitter and Desmos had even been thought of. The great Fawn Nguyen and Matt Vaudrey have raised it to an art form.

But I gambled that it would be just the antidote for the Math Plague that was threatening to decimate my classroom. Plus, worst-case scenario, I could justify it (at least to myself) by saying that the linear concepts and DOK 3 activity would be ideal for my students in the weeks leading up to ISTEP re-testing season.


I leaned heavily on Mr. Vaudrey, who is kind enough to post his materials for anyone to use, and to reflect on his own lessons so that folks downstream might be able to anticipate the stumbling blocks for their students. I teach in the new STEM wing of my school, in what eventually will be a combo computer lab and build/makerspace. So I had some essential ingredients on hand: measuring tools, lots of space, and plenty of surfaces at a variety of heights. What I didn’t have on hand, I sought out: eight bags of #32 rubber bands at WalMart, and 8 WWE wrestling figures from my son’s collection.

Day One I tried to hook them in with an insane missile silo bungee jump, then set them up with a figure, a bundle of ten rubber bands, a data collection sheet, and let them go about the business of jumping.

Perfect world: each group of three or four students would have had about 8-10 data points. Reality: most got 4-5. Several got only 3, and one group managed to record only one distance. Those guys are gonna need some extra support.

Day Two, time for some estimates backed up by math: How many bungees would be needed to jump off the top of my projector? How far a jump could their figure make with 25 bands?

And in one of those glorious moments of teaching, I had set the hook. Students were madly pouring over their data, trying to use it to give legit estimates to the questions.

Teamwork, baby. Teamwork.

(It was about this moment that I decided that I would honor their efforts at thinking and reasoning and doing actual math on their own by entering some points for the three-day project as a quiz grade. By department policy quizzes and tests account for 75% of a student’s grade, so a good quiz grade is like finding a hundred-dollar bill on the ground outside your classroom.)

So we dumped data into a Desmos graph, let some groups with few data points share some numbers from other groups (that’s that extra support we talked about), made a trend line, set a horizontal line at 533 cm on their graph, and talked about how many bands they’d need to safely make a jump from the top of our two-story Robot/Quadcopter Arena.

Letting Desmos do the heavy lifting to free up brain power for thinking.

Quick group huddle to compare numbers, then after a few minutes of table talk I stopped to see each group, ask about how they came up with their number, and (this is key) have them agree on one number, write it down on their page, and circle it.

Day Three, the Tournament Selection Committee has announced the pairings, and the teams are ready to jump.

Not that I’m craving attention or anything, but yeah, I totally posted the brackets on the window of the arena that faces a heavily traveled hallway.

I pre-assembled strands of ten bands to accelerate the assembly process, then students built their bungees and gathered, two teams at a time, on the second floor. We quickly found out that everyone in my 2nd hour class had seriously miscalculated the number of bands they needed. Fig after fig crashed to the floor. Lacking other options, and wanting to avoid the buzzkill of a six-way tie for last, we finally decided the “less dead” fig would move on.

The afternoon class seemed to have had some better estimates and we had some competetive matchups, as well as some gamesmanship as some teams attempted to scrunch two or three bands together in their hand on the railing to avoid a figurative skull fracture (high school kids, right?). The extra-long bungees in 2nd hour made a great math conversation starter (“what happened, you guys?”). I used Matt Vaudrey’s feedback form, and found out that Barbie Bungee was a near-unanimous hit.

Would this three-day activity had made more sense back in September when we were doing linear stuff? Probably. Would I have had the confidence to step back from the curriculum map for a minute when my students needed a breather if I hadn’t been hanging out on the periphery of the #MTBoS with its brilliant minds and fantastic lessons and activities? No way. Would I have tried Barbie Bungee without being able to follow a well-worn path? Not sure. I’m down with taking chances in the classroom, but I’m not sure I’d have been wise enough to add the Desmos piece if Vaudrey hadn’t blogged about it. And that made the whole project. We’d have been dead in the water, guessing a number of rubber bands for the Big Jump without it. Which means we would have missed the math altogether.

What I do know is: my students bought it, real learning happened, we all got the stress relief we needed, and I came out looking like an improv artist taking a prompt and making comedy gold.

Brian Flanagan would have been proud. Jane Craig too.

Art. And Science. It’s a Both/And.
