    "You'd think that with all their Googling to find the Spark Notes of the novels they didn't read, today's students would understand how the search engine works. Wrong: They are completely clueless! In a detailed study of 30 college students by anthropologists at Illinois Wesleyan, only seven were able to do a "reasonably well-executed search." According to Inside Higher Ed: They were basically clueless about the logic underlying how the search engine organizes and displays its results. Consequently, the students did not know how to build a search that would return good sources. (For instance, limiting a search to news articles, or querying specific databases such as Google Book Search or Google Scholar.) Duke and Asher said they were surprised by "the extent to which students appeared to lack even some of the most basic information literacy skills that we assumed they would have mastered in high school." Even students who were high achievers in high school suffered from these deficiencies, Asher told Inside Higher Ed in an interview."

    "As web companies strive to tailor their services (including news and search results) to our personal tastes, there's a dangerous unintended consequence: We get trapped in a "filter bubble" and don't get exposed to information that could challenge or broaden our worldview. Eli Pariser argues powerfully that this will ultimately prove to be bad for us and bad for democracy. "

Human Science Language evidence

  • “Once you are trilingual,” she said, “your brain can break down new languages that make it so much easier to learn your fourth, fifth and sixth languages.”
  • In fact, research shows that learning a second language makes it easier to learn additional languages. In recent years, a number of neuroscientists and psychologists have tried to untangle the impact of bilingualism on brain development. “It doesn’t make kids smarter,” said Ellen Bialystok, a professor of psychology at York University in Toronto and the author of “Bilingualism in Development: Language, Literacy and Cognition.” “There are documented cognitive developments,” she said, “but whatever smarter means, it isn’t true.”
  • Ms. Bialystok’s research shows that bilingual children tend to have smaller vocabularies in English than their monolingual counterparts, and that the limited vocabulary tends to be words used at home (spatula and squash) rather than words used at school (astronaut, rectangle). The measurement of vocabulary is always in one language: a bilingual child’s collective vocabulary from both languages will probably be larger.

  • “Bilingualism carries a cost, and the cost is rapid access to words,” Ms. Bialystok said. In other words, children have to work harder to access the right word in the right language, which can slow them down — by milliseconds, but slower nonetheless.
  • At the same time, bilingual children do better at complex tasks like isolating information presented in confusing ways. In one test researchers frequently use, words like “red” and “green” flash across a screen, but the words actually appear in purple and yellow. Bilingual children are faster at identifying what color the word is written in, a fact researchers attribute to a more developed prefrontal cortex (the part of the brain responsible for executive decision-making, like which language to use with certain people). Ms. D’Souza said that both of her sons lagged their peers by almost a year in verbal development. Her pediatrician recommended speech therapy, and one son’s preschool teacher expressed concern that he did not know the alphabet. But when both started speaking, at around 3 years old, they were able to move fluidly among three languages. She said that her older son tested in the 99th percentile for the city’s gifted and talented program. “The flexibility of their thinking helps them in nonlinguistic abilities like science and math,” she said, speaking of her children. “But at the same time the normal things — the alphabet — they have trouble with that.”
  • George P. Davison, head of school at Grace Church School, a competitive downtown school, said that bilingualism tended to suppress verbal and reading comprehension test scores by 20 to 30 percent for children younger than 12. “If anything, it can have a negative effect on admissions,” he said.

    Parenting sites indicate many New York City parents want caregivers to teach their children a language.

    Some interesting questions as to whether parents can "know" it's a good thing or a bad thing to have their children learn a second language. There are clearly cognitive and social costs and benefits that must be weighed.
