It suggests that through television it is possible to teach children a language not spoken at home or in the every-day environment:
After just one year of age, “E”, began to communicate with her father in Venetian and in Armenian language with his mother. The evening after supper, every single day, “E” has to see a cartoon or a movie for kids in FRENCH language for about an hour. This block of french language cartoons consisted of about 2/3 weeks alternated by another block of 2/3 weeks of cartoons or movies in RUSSIAN language.
I have no experience in raising polyglot children but it seems to me that they can get to understand a new language only in an interactive way (mostly by speaking it). This that cannot be done with television. So I am a bit skeptic.
Do anyone ever heard of similar approaches? Do you think that they're reliable?
