School leaders are asked lo be more open to, and lo co-operate with, local community organisations, such as sport clubs, cultural centres and other associations. For example, schools can co-operate with local sports clubs to teach English or maths through physical exercise. In 2014, the government allocated funding to 15 schools, for the academic year 2015/16, to experiment with outdoor education and demonstrate how it could work. In 2014, the Danish government developed a booklet on the "grey zone" of language that can be used by volunteers working in homework cafes, a well-developed system of places, often libraries, where students can go after school to receive help on their homework.
