Total immersion works a helluva lot better for those learning a foreign language.
Yep. Why cater to them?
Of course, being bi-lingual or tai-lingual is a good thing (and I wish I was). Linguists say your mouth muscles haven’t “frozen” until about age 11 or 12 and before that age you can learn another language without any accent.
My Dad arrived from Germany in 1927 when he was 3. He had an older brother and sister with Mom and Dad. For Dad, it was learn English via total immersion or get beat up every day on the streets of NYC. His English was so good that you’d never know that Dad only spoke German through age 3 (of course, the typical 3 year old has a 200 or more word vocabulary and speaks in three- or four-word sentences).
Yep. I like to use reality tests when confronted with these kinds of issues. Here is the Bilingual Education Reality Test: If your pay depended upon how much English the kids actually learned, what method would you use?
