NBC晚间新闻 西雅图学校发现多睡觉可提升学生成绩

It's a familiar scene in American schools. Teenagers struggling to stay awake in class. I just crave¹ sleep sometimes. So two years ago Seattle Public Schools decided² to push start time back almost an hour from 7:50 a.m. to 8:45 a.m. It is fantastic. In a new study by the university of washington researchers using activity watches to track sleep patterns of 10th graders. so this is sole activity. Found real benefits. I really like that you can see the pattern of their school day.

They got an average of 34 minutes more sleep per night, grades up by 4.5%, better attendance too. Teachers say at first some parents resisted the schedule change because it was throwing off their routines, but now they're hoping it's a wake-up call for other districts. It is so much more fun to teach kids who are more awake and more ready to talk about what they're learning. One school district, a lot less sleepless³ in Seattle.

在美国校园，有一个很常见的现象，就是学生们争取在课堂上不犯困。有时候我就是很想睡。所以在两年前，西雅图公立学校决定将上课时间从原来的早上七点四十五分延后到八点四十五分，延后了将近一小时。这太棒了。华盛顿大学的研究人员进行了一项新研究，他们使用运动手表跟踪10年级学生的睡眠模式。睡眠是唯一的活动。他们发现了这一决定带来的实实在在的的好处。你可以看到他们在上学日的睡眠模式。学生们每晚平均可以多睡34分钟，学习成绩上升4.5%，出勤率也变好了。学校老师说起初学生家长是反对这个上课时间变化的，因为这也会改变他们的时间安排，但是现在他们希望这是给其他区敲响的一个警钟。能在孩子们更清醒、更愿意讨论他们学习的东西的情况下教学，是很有乐趣的。在西雅图这个学校，学生上课犯困现象明显减少。
