PDHPE plays an important role in primary school students' development by encouraging understanding of self and others, promoting physical activity, and emphasizing informed decision making. It encourages communication and interpersonal skills, balanced eating habits, and the ability to identify drugs and their effects. PDHPE also encourages locomotor skills like running and jumping, manipulative skills such as catching and throwing, and games skills to enhance future performance. To maximize the benefits of PDHPE, lessons should be fun and involve everyone, be well prepared with limited wait times, and be targeted to students' abilities.
