And how many kids that did not play Oregon Trail know that people ever got in wagons and had a hard time getting to the West. (Where is the West anyway? Why didn't they just fly or take the bus?) I do not suggest that Oregon Trail was great for teaching history. It was not. But it did teach some history.
Civilization is a better example. I have run programs that used Civilization with close to realistic maps and poor middle school kids. Did they become historians - No. But did they have a better idea of the map of the world and how technology changed with different era's in world history. Well Yea. Did they find it hard to learn. Surprisingly yes.
I guess it depends on where you are, what looks like progress?
Another open source Avonics system is from the Portland State Aerospace Society. http://psas.pdx.edu/AvionicsTeamHome/
Probably not as relevant as the Paparazzi team since they tend to fly straight up and straight down
We (DANEnet) did several robotics groups in mandatory summer school a couple of years ago. We started kids off with Robosapiens. That is a controller based pre built robot. This was good for 1-2 sessions. Then we moved them onto the great Robodance program (free software to do visual programming on a pc using a USB wireless remote to control the Robosapiens). Another couple of sessions. Finally we went to Lego Robotics based program.
We lost some kids at each step. The step to Lego Robotics was particularly hard for these kids. One of the best groups was a mix of bilingual and solely Spanish speaking kids. Shades of the undocumented high school students that won a national college robotics competition http://www.wired.com/wired/archive/13.04/robot.html
Ya'll hear about the geometer who went to the beach to catch some rays and became a tangent ?
