The Second World-Wide Survey of Physical Education in schools, published under the auspices of the International Council of Sport Science and Physical Education, identifies large gaps between the promise of positive outcomes of physical education and actual outcomes. The mismatch between the policy and practice of physical education stems from deep-seated disagreements about what the goals of physical education should be; the multifaceted nature of the subject; and a lack of competence, confidence, and accountability among the teachers who are responsible for teaching physical education in schools, among other things. According to the World Health Organization, the physical and holistic health of young people and adults is threatened by increases in obesity, diabetes, heart disease, and certain cancers—in part due to increased sedentary modern lifestyles and insufficient exercise. Physical education has the potential to ameliorate the negative impact of sedentary lifestyles and exercise insufficiency. Teacher-education programs for physical education the world over advertise that teachers of the subject help young people acquire a love for physical activity and the skills to practice and enjoy sports; they also teach life skills, including teamwork, sportsmanship, problem-solving, and creativity, and help students develop the habits of a healthy lifestyle. How programs prepare physical-education teachers to deliver on these promises varies considerably. According to the Organisation for Economic Co-operation and Development, Singapore has one of the best-performing teacher-education systems in the world. It is run by the National Institute of Education in Singapore. The tight coupling of theory and practice and the tripartite relationship between the policymakers at the Ministry of Education; the National Institute of Education, where teacher training occurs; and the schools, where physical education is experienced, are the key determinants of a quality physical-education experience among children and adolescents in Singapore.
