Game sense is an approach to teaching physical education that focuses on learning skills through modified games rather than isolated drills. It emphasizes student engagement and collaboration through open-ended questioning and cooperative gameplay. There are four categories of games - invasion, net/wall, target, and striking/fielding games. The game sense approach provides benefits like inclusion of all students, collaboration, autonomy, enjoyment, and intellectual engagement through reflection. It aligns with teaching philosophies that emphasize student-centered learning, fun, and a constructivist approach where students actively construct their own understanding through social engagement.
