Teachers get ___1___ at students—they don’t pay attention, they’re sleepy, they have bad attitudes. But improvement could be a matter of timing—just start school later. That’s according to a study in the Archives of ___2___ and Adolescent Medicine.
Beginning at adolescence, kids have what’s called a ___3___, where they start sleep later and sleep later in the morning. And they need plenty—about nine-and-a-quarter hours a night.
The researchers evaluated 201 Rhode Island high school students whose school ___4___ its start time from 8 to 8:30. The kids completed a sleep habits survey before and after the time change.
After the delayed start, the percentage of students who said they got at least eight hours of sleep a night jumped from about 16 to 55 percent. Class attendance improved, and there were fewer visits to the health center for ___5___. Plus, the number of students who said they felt unhappy, depressed, annoyed or irritated dropped significantly.
Before the study, teachers, coaches and administrators all resisted the later start. After, nearly all voted to keep it in place. A half-hour change for happier, better students? Seems like a good time for all.

学生的表现着实令老师恼火。他们听课心不在焉，昏昏欲睡，态度恶劣。但要改变这一状况只需在时间安排上稍作调整——学校晚点上课就好了。《儿科学与青少年医学档案》发表的一项研究为此提供了依据。
进入青春期，孩子们会出现一种叫“睡眠相位后移”的睡眠紊乱，晚上睡不着，白天醒不来。他们需要很长的睡眠时间——每晚9小时15分钟。
研究人员对罗得岛州201名高中生进行了调查分析，这些学生的学校将开课时间从早晨8点推迟到8点30。在此前后，学生们填写了一份关于睡眠习惯的调查问卷。
上课时间推迟后，55%的学生反映每晚至少得到8小时睡眠，而此前这一比例仅为16%。课堂出勤率得到了改善，因疲乏相关疾病就医的人数下降。此外，反映自己情绪低落、压抑、困惑、烦躁的学生大大减少。
研究开展之前，老师、辅导员及校方管理人员一致反对延迟开课。但现在，几乎所有人都投票赞成继续实行这项措施。每天推迟半小时，让学生们更高兴、更优秀？看起来是个皆大欢喜的结局呢。
