I was doing some research into game-based learning and came across a NASA-sponsored project that allows students to learn about the moon through an online game called Selene.
The game can be located here: http://cygames.cet.edu/
I haven’t tried it out yet because they have a bit of a bureaucratic method of getting people online – you need to apply to be a “recruiter”, download parental permission forms, provide phone contact information, etc. before being given an access code to use to get students online.
Part of the reason for all this is that the game is also a research project, and data will be collected from the student’s progress in the game.
Have a look at this video from NASA Education to hear a better explanation of the game than the website gives:
I aim to try it out with my class next year, but if anyone’s used it and has feedback to offer, I’m always interested.
