We were discussing the rules about how students should act when they work in groups: work to find work to do; allow people to work; be respectful; be focused on the project at hand. As the discussion evolved into what we should do about enforcement, one student suggested that positive reinforcement would be better than negative, so maybe they should get points for good behavior. Being students raised on the Harry Potter series, it was perhaps inevitable that someone would come up with the idea of separating the class into houses that could compete to see who got the most marbles/points.

Support for an inter-house competition was unanimous — after a little more discussion and explanation — and they were able to persuade me to try it. Each group would be its own house — they got to choose the names — and would earn marbles as a group.

I dug up some marbles and a few old jars overnight. I realized, however, that I’d run out of marbles pretty quickly if I gave them out as liberally as I wanted to, so I whipped up a website to keep score long-term.

They chose names. The names all ended up being Harry Potter themed — over some opposition within the groups, however. No one wanted Hufflepuff, and one group flirted with Slytherin, but we finally ended up with Griffindor, Ravenclaw, Chudley Cannons, and S.P.E.W. (Society for the Promotion of Elvish Welfare). I think they may have, briefly, given each other individual names out of the books, but I was not privy to those deliberations.

How’s it working?

It’s working remarkably well so far. It was originally their idea, and they were forced to persuade me that it was worth trying, so I think they’re well invested in making it work. Our discussions have been much more organized, with fewer people speaking out of turn. And we’ve had much more discussion and questions among them since that’s one way to gain points.

I’ve made it a point to use the physical jars with marbles. They can hear the marbles clink when they fall in, so they get direct, unobtrusive positive feedback.

I’ve also made it a rule that they don’t get points if they ask for them — to reduce the lobbying — but they can still challenge if they did not get points they think they deserved; I always encourage them to think that they’re entitled to a reasonable response from me on any subject (its a good way of keeping me honest, and it helps them see the bigger picture).

The students were also able to change my mind about taking away points. I’d originally wanted to only give positive rewards, but they thought they could handle the negatives just fine, and were kind-of looking forward to them. And I have to admit they seem to work. Now, I’m not the only one trying to keep these adolescents in line. They’re getting pressure for good behavior from their peers; a much more potent source of influence for kids in a stage that features social development.

The inter-house rivalry is also healthy enough at the moment. They’re quite happy to see the other groups loose points, but seem to realize that openly advocating for it would not be a particularly advantageous move.

At the end of the quarter, the students want some sort of reward for the house with the most points. I told them that they should make proposals, because I had no good ideas.

In all, it has started quite promisingly. We’ll see how it goes.
