In the 19th century, developmental psychologists such as Friedrich Fröbel proposed playgrounds as a developmental aid, or to imbue children with a sense of fair play and good manners.
In Germany, a few playgrounds were erected in connection to schools, However, it was only in the early 20th century, as the street lost its role as the default public space and became reserved for use by motor cars, that momentum built to remove children from the new dangers and confine them to segregated areas to play.
The place where children of tomorrow study, where the future of nation is shaped is called school. We study in our school in a great friendly environment. As soon we reach we line up for attending the assembly.
Since, education is essential weapon for tomorrow, so the good schools of today are important for the best future of a nation. Attending the school assembly is a wonderful experience.
In the United States, organisations such as the National Highway Protective Society highlighted the numbers killed by automobiles, and urged the creation of playgrounds, aiming to free streets for vehicles rather than children's play.
In tandem with the new concern about the danger of roads, educational theories of play, including by Herbert Spencer and John Dewey inspired the emergence of the reformist playground movement, which argued that playgrounds had educational value, improved attention in class, enhanced physical health, and reduced truancy.
Some of the most common constructions were the carousel, sphere, seesaw, rocket, bridge, etc.
Playground design is influenced by the intended purpose and audience.
A playground, playpark, or play area is a place specifically designed to enable children to play there. While a playground is usually designed for children, some target other age groups.
Berlin's Preußenpark for example is designed for people aged 70 or higher.
