Swanson School signed up to the study by AUT and Otago University just over two years ago, with the aim of encouraging active play. However, the school took the experiment a step further by abandoning the rules completely, much to the horror of some teachers at the time, he said.When the university study wrapped up at the end of last year the school and researchers were amazed by the results. Mudslides, skateboarding, bullrush and tree climbing kept the children so occupied the school no longer needed a timeout area or as many teachers on patrol. Instead of a playground, children used their imagination to play in a “loose parts pit” which contained junk such as wood, tyres and an old fire hose. —National News | TVNZ.
