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.

Getting your kids excited about science

There was an amazing blog posting in my twitterstream this morning, thanks to @SkepticsGuide and @COmtnClimr. Steven Novella posted A Parent’s Approach to Science Education. If you’ve got kids (or nieces, nephews, neighbour’s kids, hell, even the neighbours) and you want to enrich their science education and, more importantly, get them excited about science, you should read his post. It’s full of great advice. Nice shout out to astronomy, too.

The birth of a clicker question

It’s easy to come up with poor clicker questions, ones that merely test who has memorized X, Y, or Z from the previous slide. Or questions where there is no way to figure out the answer: either you’ve got it or you don’t.

Good clicker questions, on the other hand, take some time to create. Sure, you might stumble onto a good one every now and then, and it gets easier as you do it more. But it’s really gratifying when you put in the time, and it works. Here’s my story.
