So I spent entirely too much of the past week writing something akin to a live-action role playing game. In class on Friday (and continuing into at least part of this coming Monday), the students became world class scientists trying to figure out the "newly discovered" photoelectric effect. They're each a supporter of one of two competing theories of how light (classical electromagnetic waves) interacts with a metal surface to eject electrons and cause current to flow. On Friday, I welcomed them to the conference in the role of the physics department chair at the host institution:
[I stole this picture from a student's public Facebook post, by the way: thanks David T!] In their two big groups and then in six smaller lab groups, the students assembled a set of graphs illustrating their competing predictions, and then the leader of each main group presented their results to the conference.
And after that, the experimental data came in ("from the experimental conference down the hall"). Both groups got some things right, but fundamentally, everyone was wrong! So on Monday we reconvene to see if we can puzzle out the true story. I have absolutely no idea how that's going to go. I've tried to seed elements of the real (quantum!) explanation among them, and if anyone is particular clever or eager to get it right they might think to actually read the textbook. (On their own!) We'll find out! If nothing else, it was clear that they had a lot of fun with the activity, and they really were thinking hard about what their predictions should look like. I feel good about it.
In case you're curious, I'm including a glimpse of one character sheet here. I'll stick it behind a cut: ( The first page of Prof. Parma's character sheet. )
