想提升学生上课专注力？把椅子换成运动球试试！
Sitting on a chair all day in school can make anyone want to move around. So, more and more teachers are asking students to sit on a ball. By sitting on exercise balls instead of chairs, teachers find students’ attention improved. What’s more important, it’s very interesting and exciting.
Peter, a fifth-grade teacher in West Virginia, the USA, has been using balls as chairs since December 2015. “The students love them,” he says. Peter took a survey of his students. 80% of the students reported that sitting on the balls helped them pay more attention to what they were learning. They can focus on what their teachers are teaching.
The manager(经理), Mary, felt so strongly about the use of balls as chairs. She encourages the use of the balls. She hopes not only teachers but also students know how to use them. “Our products are used in 24 states, three provinces in Canada, Puerto Rico and Japan,” says Mary. “Research shows that sitting on the balls makes them sit up straighter,” says Mary, “but they never get bored.” Because the students are moving, so the kids have more energy and can keep focused longer. “Besides, they’re fun,” says Peter.
