Something happens to many children when they are out of school over the summer months. It is called the “summer slide.” This may sound like a ride at a water park. But it's not. Summer slide is when children forget much of what they learned during the latest school year.

    To fight the effects of summer slide, teachers often give students homework over the summer. Many parents may send children to all kinds of camps or find other activities to keep them learning. Some even try to build up their children's strengths by getting them into extra tutoring.

    However, experts say keeping children busy all the time is not good for them. The result is often a tired child with an overcrowded schedule. This keeps a child's brain active constantly—learning, gathering information and preparing for the next event. And this may have the opposite effect the parents are not hoping for.

    What should parents do instead? Nothing. According to Lea Waters, a psychologist specializing in positive psychology and positive education, slowing down actually helps children become the best they can be. Machines need to be reset, while kids need to goof off（偷懒）. She says that goofing off really allows kids to have some downtime, when they're not focused on a specific task but are free to do something that they're interested in doing and that they can do more automatically and get enjoyment from, like shooting baskets or listening to the music.

    She also adds that goofing off does not mean the brain isn't working. It just goes into this default network mode（默认网络模式）and uses that time to process all the information it had during the day, to integrate（整合）new information. It makes a kind of decision about what information to put into memory and what to get rid of, which in fact helps to improve memory.
