I went to Games+Learning+Society to present Mecanika’s impact in Quebec classrooms, and was surprised by the amount of physics games I saw there. Here’s the description.
It turns out that most physics games out there do not seem to have results as strong as what we've recorded. I just submitted proceedings on the actual results, which I'll link to here later. But briefly: the game caused a large measurable increase on the Force Concept Inventory, and that effect was observed whether or not we added classroom debriefings and detailed guidebook activities about the game. These results are pretty solid since we used a control group and pre/post tests.
So my goal right now is to put this game in front of as much teachers as I can, for free. They don't even have to look at the game themselves! As long as they ask their students to play it at home, they should see a difference in students Newtonian conceptions.
