Why using games in the classroom?

There are many reasons why games should be used in the classroom. In today's post I will focus on the most relevant ones:
1) Games portrait real life. There are RULES, OBJECTIVES and OBSTACLES.
2) Games are voluntary.
3) Games offer choices.
4) Choices have consequences.
5) Consequences offer feedback.
6) Games offer freedom to experiment.
7) Games offer freedom to fail.
8) Games offer freedom to try on different identities.
9) Games offer freedom of effort.
10) In games, participants are involved in an imaginary situation, with explicit roles and implicit rules ( Vygotski)
11) Games lead to a greater degree of self-regulation, the participants actions being determined by the rules of the game. (Vygotski) .
12) When involved in games, participants' concentration and application to the task are much greater than in academically-directed activities contrived by the teacher.
