Recess (课间休息) time has been dropping for many children in America. This drop began the same year the No Child Left Behind Act (NCLB) was passed. The law aimed to make American education system more internationally competitive by introducing achievement goals for schools. And the goals are gauged (评定) by standardized tests in reading and math. If schools missed their achievement goals, they could be in trouble, including loss of funding.

It's no surprise that teachers have felt the pressure to make sure students perform well on standardized tests. When educators are facing pay cuts, loss of funding to their school and perhaps even the loss of their jobs, it's no wonder that they started questioning if recess was a waste of time. This pressure to bring even more learning into the school day is especially felt by underperforming, low-income schools that are already short of funding.

It may seem strange to send kids out to play when they're falling below state standards, but getting outside for unstructured (散乱的) play may be more helpful than keeping kids in the classroom all day.

"Moving, running and playing outdoors freely have great influence on children. These activities play a role in children's abilities to focus and control themselves throughout the day," Marie Conti says, a famous educator of early childhood education. The mind cannot be educated without using the body. Learning is a whole of thinking and moving," she added.

Recess time makes it possible for children to learn something they can't get in class. Asking other kids to play, explaining the rules of a complex game and ending arguments are all important life lessons that children can only learn if they're given time to play. When something unhappy happens, children can find a way to get back to having fun themselves.

The physical activities kids take part in during recess can also reduce stress levels and allow children to feel more relaxed. In an education system that. Continues to place higher expectations on children to perform to a certain standard, less stress is just what the doctor ordered.
