This is true for many children of non-English speaking immigrant parents anywhere in the developed world. Schools will use language immersion and extra help to get these kids up to speed very quickly. Computers are sometimes used for educational games and activities, but these can be done just as well without.

Can I guess that you are (native/ethnic) Norwegian and upset by the recent waves of immigration to Norway? Your comment is very specific, plus you used a new throwaway account.

No, they don’t. Especially in elementary school.

My living example - my kiddo didn’t speak a word in English until 4.5 years, when she went into preschool. Russian speaking home and daycare do that for you.

After 9 months in American preschool, she completely switched to English language as her primary. 2 years later, and she speaks Russian with strong accent.

Do you have a source for this?
