A model of classroom gamification is Steven L. Johnson, an assistant professor of management information systems at Temple's Fox School of Business. He created a Social Media Innovation Quest where students earn points and receive badges. "You will always have your top performers, and you'll always have students who struggle, no matter how many incentives you throw at them," he said. "A well-designed gamification system has the most impact on the middle 40 to 60 percent of students. It motivates these students to do more."
