Gee:

"There are nearly always multiple solutions to any given problem. Players can choose strategies that fit with their style of learning, thinking, and acting. This, of course, is highly motivation both for learning and for playing the game and a rich source for reflection on one's own styles of learning and problem solving" (p. 78).

McNiff:

In Mathematics classes the student is taught a way to solve a problem and often detoured from using other methods to solve because it will cause "problems" when solving larger problems. Some math teachers, depending, will show students two ways of solving a problem and allow the student to pick "whichever is easiest" for the student to learn to solve the problem. I realize that in high school mathematics, when students should be thinking critically, problem solving/equations and formulas are rarely paired with theory/explanation and critical thinking.

In foreign language classes in high school students have to write, read and communicate in another language. In mathematics, students aren't taught to speak about math and theories, definitions.
