Children have devised many playground games and pastimes. But because playgrounds are usually subject to adult supervision and oversight, young children's street culture often struggles to fully thrive there. Research by Robin Moore (Childhood's Domain: Play and Place, 1986) has clearly shown that playgrounds need to be balanced with marginal areas that (to adults) appear to be derelict or wasteground but to children they are area's that they can claim for themselves, ideally a wooded area or field.
Playgrounds originiated in Germany. They were created as organized and instructional play areas for the use of teaching children the proper ways to play. Over time, organized playing areas have been adopted by other countries of the world and have become commonplace. The widespread adoption of playgrounds led to the Germanisation of some aspects of childhood development.
A type of playground called a playscape can provide children with the necessary feeling of ownership that Moore describes above. Playscapes can also provide parents with the assurance of their child's safety and wellbeing, which may not be prevalent in an open field or wooded area.
