A Metacognitive Moment

We’re beyond the halfway point in most classes, and it may be a good time to take just a (metacognitive) moment to review progress and map the road ahead.

In my physics class, I ask students each day as part of their class preparation to attempt an explanation of a real or simulated physics result. The question is based on material to which they’ve just had their first exposure, by reading or video lecture. It’s challenging, and initially not well liked. But it’s definitely something at which students improve with practice. They become not only more willing to “guess,” but they begin to support their answers with evidence, independent research and/or mathematical analysis far more often.

When I recently told my students that I had begun seeing that progress, a number of them spontaneously reflected and then shared agreement that this was getting more comfortable. It’s easy to lose track, in mid-semester, of how far you’ve come already. And it can be highly motivating to students when they see progress. In a similar way, looking backward momentarily can sometimes help put what remains in perspective.

As a physics student, when I first learned about rotational motion, I missed the idea that every rotational quantity had a linear analog. I struggled mightily as I tried to learn rotational kinematics in about a week, and the pace seemed completely unreasonable to me given that we’d spent about seven weeks learning the same concepts for linear motion.

This week, as I teach the same material, I explicitly connect each new rotational quantity back to the linear one. This seems to help students not only absorb the new material but reinforces the old and makes the pace more reasonable. A look backward could be an open-ended reflection on progress, or an explicit challenge to make comparisons to, connections with, or predictions about what’s coming. It could be done as a formal assignment, an in-class exercise, as a “minute paper” reflection near the end of a class or through a Canvas survey or quiz.

If you’re looking for other instructional strategies (and don’t want to wait for next week), stop into or contact the Jackson Center for Teaching and Learning.

Probing Quantum Phenomena in Tiny Transistors

Nearly a thousand times thinner than a human hair, nanowires can only be understood with quantum mechanics. Using quantum models, physicists from Michigan Tech have figured out what drives the efficiency of a silicon-germanium (Si-Ge) core-shell nanowire transistor.

The study, published last week in Nano Letters, focuses on the quantum tunneling in a core-shell nanowire structure. Ranjit Pati (Physics) led the work along with his graduate students Kamal Dhungana and Meghnath Jaishi.
