Nowadays, the world is developing in a fast way, so it is very important for students to be good at skills such as solving problems, making decisions and critical thinking(批判性思维). It is said that all these skills appear in StarCraft. Therefore, StarCraft can provide a high effective environment for students to consider and take action in difficult situations.

“A student who gets a university education and goes into the business world could realize that something he learned in his StarCraft class helps him to think in a different way,” said one teacher in the University of Florida.

“The StarCraft class offers a new way to students to study. Study is not only about learning things from books,” said another teacher.

Not all the students can take the StarCraft class. The class is only open to the students who have some knowledge about the game.
