For my dissertation, I am investigating Higher Order Thinking Skills (analyzing, evaluating, and creating) in digital games.  I would like to find games, on the iPad, that develop these skills.  Unfortunately, I have not found many games for middle school and High school students which develop Higher Order Thinking Skills.  If you have discovered some of these games, please let me know, so that I can include them in my dissertation.

Thanks.
