1 . It’s normal for teens to want to stay connected with friends and social circle, but what about that happening in the middle of the night? The Journal of Youth Studies recently published new research showing that one in five teens from 12 to 15 regularly wake to spend all night on social media (社会媒体). Not surprisingly, the research also showed that these social night owls were three times more likely than others to feel tired at school and that girls were more likely than boys to be called to office.
The blue light produced by cell phones and computers makes the brain to stay awake, so it's easy to see why a teen might be up all night. A study in Psychological Science showed the same brain reaction: when teens saw large numbers of “likes” on their posts, they stayed awake with excitement as if they had eaten chocolates or won money. Besides not catching up on sleep and interrupting their sleep cycle, teens may never fully enter deep sleep that may be responsible for brain development and learning.
Considering about 72 percent of children from 6 to 17 sleep with some electronic media in their bedrooms, parents need to set rules sooner rather than later.
“Providing access (使用机会) to social media is a favor that children can earn and also lose,” Janie Feldman, an expert who treats sleep disorders (紊乱), reminds parents, “The bad effect is clear. So teens and parents should discuss and agree on its use, timing and access. When teenagers agree to the rules, it’s easier for parents to control how much time they use the phones or computers.”

2 . Traditionally, across the world, boys and girls attend a mixed school, where they study together. But boys’ schools are the perfect place to teach young men to express their emotions and involve them in activities such as art, dance and music.
Boys at single—sex schools were said to be more likely to get involved in cultural and artistic activities that helped develop their emotional expressiveness, rather than feeling they had to correspond to（和……相符）the “boy code” of hiding their emotions to be a “real man”.
The findings of the study go against received wisdom that boys do better when taught alongside girls.
Tony Little, headmaster of Eton, warmed that boys were being failed by the British education system because it had become too focused on girls. He criticized teachers for failing to recognize that boys are actually more emotional than girls.
The research argued that boys often perform badly in mixed schools because they become discouraged when girls do better earlier in speaking and reading skills.
But in single-sex schools teachers can tailor lessons to boys’ learning style, letting them move around the classroom and getting them to compete in teams to prevent boredom, wrote the study’s author, Abigail James, of the University of Virginia.
Teachers could encourage boys to enjoy reading and writing with “boy-focused” approaches such as themes and characters that appeal to them. Because boys generally have more acute vision, learn best through touch, and are physically more active, they need to be given “hands-on” lessons where they are allowed to walk around. “Boys in mixed schools view classical music as feminine（女性的）and prefer the modern genre（类型）in which violence and sexism are major themes,” James wrote.
Single—sex education also made it less likely that boys would feel that they had to be “masterful and in charge” in relationships. “In mixed schools, boys feel forced to act like men before they understand themselves well enough to know what that means,” the study reported.
