The document discusses Game Sense, which is a student-centered teaching approach used in physical education. Game Sense allows students to develop skills within a game setting by modifying activities to suit different ability levels. It focuses on learning techniques through playing games first before focusing on mechanics. Game Sense is beneficial as it encourages cooperative learning, develops cognitive skills, and aligns with outcomes in the NSW PDHPE Syllabus such as participating in sports and understanding the health impacts of physical activity.
