TV is bad for children's education, studies say

科學(xué)研究表明:看電視不利于兒童教育

The more time children spend watching television the poorer they perform academically, according to three studies published on Monday.

Excessive television viewing has been blamed for increasing rates of childhood obesity and for aggressive behavior, while its impact on schooling have been inconclusive, researchers said.

But studies published on the topic in this month's Archives of Pediatrics & Adolescent Medicine concluded television viewing tended to have an adverse effect on academic pursuits.

For instance, children in third grade who had televisions in their bedrooms -- and therefore watched more TV -- scored lower on standardized tests than those who did not have sets in their rooms.

In contrast, the study found having a home computer with access to the Internet resulted in comparatively higher test scores.

"Consistently, those with a bedroom television but no home computer access had, on average, the lowest scores and those with home computer access but no bedroom television had the highest scores," wrote study author Dina Borzekowski of Johns Hopkins University.

American homes with children have an average of nearly three televisions each, the report said, and children with televisions in their bedrooms averaged nearly 13 hours of viewing a week compared to nearly 11 hours by children who did not have their own sets.

The American Academy of Pediatrics has urged parents to limit children's television viewing to no more than one to two hours per day -- and to try to keep younger children away from TV altogether.

In two other studies published in the same journal, children who regularly watched television before the age of 3 ended up with lower test scores later on, and children and adolescents who watched more television were less likely to go on to finish high school or earn a college degree.

University of Washington researchers reported that 59 percent of U.S. children younger than age 2 watch an average of 1.3 hours of television per day, though there is no programing of proven educational value for children that young.

TV watching appeared to help 3- to 5-year-olds with basic reading recognition and short-term memory, but not reading comprehension or mathematics, so the net effect of television watching is "limited in its beneficial impact," wrote study author Frederick Zimmerman.

本周一(7月4日)發(fā)表的三份研究報(bào)告聲稱,兒童花在看電視上的時(shí)間越多,他們的學(xué)習(xí)成績(jī)就越差。

研究人員說(shuō),人們一直將兒童肥胖和過激行為的日益增多歸咎為看電視太多,但是,關(guān)于看電視對(duì)兒童的學(xué)習(xí)的影響到底有多大,目前還沒有定論。

不過,本月刊登在《兒科和青春期醫(yī)學(xué)檔案》上的有關(guān)這個(gè)話題的三份報(bào)告得出結(jié)論說(shuō),看電視容易給孩子的學(xué)習(xí)帶來(lái)不利影響。

文章舉例說(shuō),如果一個(gè)三年級(jí)孩子的臥室里放有電視機(jī),這樣孩子就會(huì)經(jīng)常看電視,那么他在標(biāo)準(zhǔn)化測(cè)驗(yàn)中的分?jǐn)?shù)將低于那些臥室中沒有電視的孩子。

相反,研究還發(fā)現(xiàn)如果孩子的臥室里配有接入互聯(lián)網(wǎng)的電腦,孩子在考試中就會(huì)獲得相對(duì)較高的分?jǐn)?shù)。

“通過我們長(zhǎng)期的觀察發(fā)現(xiàn),一般情況下那些臥室里有電視而沒有電腦的孩子成績(jī)最差,而那些臥室里有電腦而沒有電視的孩子的成績(jī)最好,”研究報(bào)告的撰稿人、霍普金斯大學(xué)的迪娜·勃爾杰克夫斯基寫道。

這份報(bào)告聲稱,有孩子的美國(guó)家庭平均每戶有近三臺(tái)電視。那些臥室里有電視的孩子每周看電視的平均時(shí)間約為13小時(shí),而那些臥室里沒有電視的孩子每周看電視的時(shí)間則只有11個(gè)小時(shí)左右。

美國(guó)兒科學(xué)會(huì)敦促家長(zhǎng)們把孩子每天看電視的時(shí)間限制在一到兩個(gè)小時(shí)之內(nèi),并且讓年幼的孩子們遠(yuǎn)離電視。

根據(jù)同期雜志刊登的另外兩份研究報(bào)告,如果孩子在三歲之前經(jīng)常看電視,他以后的學(xué)習(xí)成績(jī)就會(huì)比較差,而且經(jīng)常看電視的兒童和青少年也很少能完成中學(xué)學(xué)業(yè),更不用說(shuō)取得大學(xué)文憑了。

華盛頓大學(xué)的研究人員再報(bào)告中指出,盡管目前還沒有已被證明對(duì)年幼的孩子有教育價(jià)值的電視節(jié)目出現(xiàn),但在兩歲以下的美國(guó)兒童中,有59%的兒童平均每天看電視的時(shí)間為1.3小時(shí)。

對(duì)三到五歲的孩子而言,看電視可能會(huì)提高他們的識(shí)字和短時(shí)期的記憶能力,但是卻無(wú)助于閱讀理解和算術(shù)能力的提升。所以,看電視的“實(shí)際益處相當(dāng)有限”,報(bào)告撰稿人弗雷德里克·齊默曼寫道。
