#研究分享#【儿童网络使用情况研究】美国儿科学会成员Stephanie Ruest最近一项研究显示:日上网二至四小时的学生完成作业的概率较之低于两小时的学生降低了23%,上网四至六小时的学生则降低了49%。对此,Ruest建议2岁以下儿童应当避免使用除视频聊天之外的任何电子设备功能,而2-5岁儿童应有节制地欣赏高品质节目,5至18岁的儿童与青少年需要保证8-12小时的日睡眠时间,并让其不要养成与电视或是手机相伴入眠的情况。http://www.looooker.com/archives/36037

How long should you let your kids go online for? Experts reveal more than two hours can impact on homework - and say toddlers should be banned from tablets

By STACY LIBERATORE
It's something parents have always suspected– children are spending too much time looking at a screen and it is affecting their school work.
A new study reveals the more kids are plugged-in, the less likely they are to finish their homework.
Researcher found children who spend two to four hours a day using digital devices have 23 percent lower odds of always or usually completing school work - and the odds decrease with every additional two hours.
Today's children spend an enormous amount of time with digital media – especially those living in the US.
Kids ages eight to 18 spend about 44.5 hours per week in front of a screen, which includes smartphones, tablets, computers and televisions.
And a report from Common Sense Media found that some teens are exposed to as much as nine hours using media - which is only recreational.
A recent study from the American Academy of Pediatrics, in collaboration with Brown University School of Public Health, analyzed children's use of digital media to better understand how it relates to childhood 'flourishing'.
The team also looked at the overall positive well-being, which can be measured by behaviors and characteristics including diligence, initiative, task completion, and interpersonal relationships.

Data was gathered from the 2011 to 2012 National Survey of Children's Health to see the media use and homework habits of more than 64,000 children ages 6 to 17 years, as reported by their parent or guardian.
Media use included watching television, using computers, playing video games and using tablets and smartphones – any instance where a device was used for purposes other than homework.
And the data shows that 31 percent were exposed to less than two hours of digital media per day.
Another 36 percent were plugged-in for two to four hours each day, 17 percent were exposed to four to six hours and 17 percent used digital devices for six or more hours a day.
For every additional two hours of combined digital media use per day, there was a statistically significant decrease in the odds of always or usually completing homework.
Children who spent four to six hours on digital media had 49 percent lower odds of always or usually finishing their homework than those with less than 2 hours per day.
Those with six or more hours of media use had 63 percent lower odds of always or usually finishing their homework compared to children who spent less than two hours per day using media.

The authors found a similar relationship between digital media exposure and four other measures of childhood flourishing, including always or usually caring about doing well in school, completing tasks that are started, showing interest in learning new things and staying calm when faced with challenges.
And these trends all remained significant regardless of the child's age group, sex, or family income level.
This study adds to what is already known by showing that digital media exposure is associated with decreased measures of overall child well-being.
'It is important for parents and caregivers to understand that when their children are exposed to multiple different forms of digital media each day, the combined total digital media exposure is associated with decreases in a variety of childhood well-being measures including homework completion, task completion, interest in learning new things, and staying calm when challenged,' said study author Stephanie Ruest, MD, FAAP.
