At the Green Free School in Copenhagen, Denmark, education is all about sustainability(可持续性). There are no desk, no blackboards and no tests. Students spend much of their time studying outdoors.
A group of 12 children are sitting in a circle when the bell rings. Instead of rushing to their next class, the children close their eyes. "Raise your hand when you can no longer hear a sound," says their teacher, holding a pair of bronze cymbals. One by one, their hands go up.
"I've always learned how to be around the world in a respectful(尊重的)way. To me, it's important to create a school that would think about the green transition (过渡) we are going through," says Phie Ambo, who started the school in 2014.
Now there're about 200 students at the school. According to Ambo, some parents come because of the green transition. And some come because it's a small school and they want a closer relation to the whole school society." In Denmark we have some super schools with thousands of children and a lot of people aren't comfortable with this," Ambo explains.
The school not only serves healthy food, but it allows kids to bring whatever they want to eat. "It's to show our kids that making the whole green transition can be fun and nice and it's not about not doing things," Ambo says. "We're all taking the first steps and learning from each other."
