Using academic games in classroom lessons can significantly improve student achievement, according to Robert J. Marzano, an ASCD author and the CEO and co-founder of Marzano Research Laboratory in Colorado, who has helped conduct more than 60 studies on the practice. Marzano writes that teachers should incorporate games that offer a low-stakes competition and are focused on a particular lesson. After the game is over, teachers also should take time to discuss the results with the class, he writes in the current issue of ASCD's Educational Leadership.
