Clicker questions should be integrated, not jammed in later

The CWSEI group at UBC gets together every week to discuss a journal article. This week, it was a new article by Melissa Dancy and Charles Henderson “Pedagogical practices and instructional change of physics faculty,” Am. J. Phys. 78 (2010).

One of the questions explored in the paper is, why don’t physics faculty members adopt the research-based instructional strategies that so many have already heard of? Mazur-style peer instruction (PI) using clickers, for example.

Dancy & Henderson discovered that nearly two-thirds (64%) of the 722 faculty who completed their survey were familiar with PI and 29% actually used it in their classes. But on further probing, it turned out only 27% of that 29% (we’re down to about 8% now) had students discussing ideas and solving problems multiple times per class. It appears that a lot of physics faculty members equate “peer instruction” with “yeah, I’ve got clickers in my class.” The technology is there but it’s not being implemented in a way that promotes learning.

Using clickers to engage your audience

Today, I had the pleasure of demonstrating clickers to a group of journalists visiting UBC. They’d heard of the Carl Wieman Science Education Initiative that I’m part of, and wanted to “see clickers”.

The message I gave them is the one Tim Slater (@caperteam), Ed Prather and the rest of the team at the Center for Astronomy Education have been preaching for years: it’s not what the instructor does that matters; it’s what the students do for themselves. And clickers are a tool for facilitating this learner-centered instruction.

One thing a clicker question can do is quickly engage the audience. These journos are from France, so I posed a simple question

How tall is the Eiffel Tower?

A) 162 metres
B) 324 metres
C) 1024 metres
D) none of these

Is it important students know the height of the Eiffel Tower? No. But it engages them, gets their attention. And the crazy things is, after answering this question, you really want to know!

My audience didn’t all chose the same answer and I didn’t tell them the height. We moved on to other kinds of clicker questions: gathering predictions and think-pair-share (aka peer instruction).

But evidently the Eiffel Tower question was smoldering in a few of them because at then end of my presentation, they asked me to go back to the Eiffel Tower question, and proceeded to have a debate about its height. Apparently 324 metres is not the correct height because, as every Frenchman knows, that includes the radio antenna on the top. Or something like that. The point is, they engaged in my presentation because they had to spend a moment or two thinking and then declaring what they thought by pressing a button on the clicker.

That’s what clickers can do for you.

And once you’ve got them engaged and participating, voila, they’re ready to learn the important stuff.
