Is it true that immersion in a foreign language leads to faster fluency?
Partly. One encyclopedia entry says Canadian French immersion gives students proficiency in both official languages, and a small narrative study of three adolescents reports immersion contributed positively to oral fluency. A CLIL study, by contrast, found students improved communicative goals but not oral linguistic competence. None compares immersion against other methods for speed of fluency, so the 'faster' element is only partly addressed.
