The centerpiece of Peer Instruction is the ConcepTest, sometimes referred to as a clicker question, other times simply as a question. ConcepTests, however, are more than mere questions. They are the fire, so to speak, that draws students’ attention and calls the students together to engage in the social learning activities that make Peer Instruction work.
ConcepTests, according Eric Mazur’s book: Peer Instruction: A User’s Manual are “short conceptual questions on the subject being discussed.” ConcepTests
(a) force to students to think through their arguments being developed; and
(b) provide them as well as the teacher a way to assess their understanding of the concept. p. 10
In the past, ConcepTests were written as multiple-choice questions — and if you do any additional reading about them you will see others have defined them as such. This definition resulted primarily because of the limitations of technology to help instructors poll anything but multiple choice.
Today,with cutting edge classroom response systems there are a range of rich-response types. For example, in the ConcepTest in Figure 1 below, I used Learning Catalytics to ask my audience to identify the region of the brain responsible for vision by tapping on their screens (they were using smart phones and Tablets). You can see the blank question and the results after Round 1 of voting. The green dots represent the individuals selecting the correct region.
Another cool thing about ConcepTests is that they turn the Peer Instruction classroom into what I like to call a higher-order thinking sandbox, where students can, in a low-stakes environment, build expert-level cognitive skills that are conduits to the Holy Grail of learning – knowledge transfer (the ability to apply prior knowledge to solve problems in or navigate new, unfamiliar contexts).
Some of these expert-level cognitive tasks include the metacognitive activity of self-monitoring. When we ask students to respond to ConcepTests, we are asking them to think about what they know and what they don’t know.
It is only when students gain awareness of their knowledge through self-monitoring, that they can further engage in the kinds of activities that are the mark of the most expert learners, such as self-regulation (e.g. controlling and assessing your own learning and related learning behaviors).
Finally, ConcepTests gives students extensive practice with retrieval. As research from the folks at the Memory Lab at Washington University in St. Louis emphasize, when students are asked to retrieve information, it increases their knowledge retention.
This is the brain on Peer Instruction.
