Classroom digital games report

78% of Teachers Use Digital Games in the Classroom
Digital and traditional games play a significant role motivating, rewarding and engaging students in the classroom, according to a survey of 694 K-8 teachers. It reports that 78% of educators use digital games in class, up from 50% two years ago. Many use them more often for motivation than instruction, and 47% say low-performing students benefit the most from digital game-play. In addition, 26% use nondigital games for classroom connections and interactions.
