Immersion is the process by which children learn their native language, but it can also be used in educational settings. Apparently in some countries, where the official language is not the language that is actually spoken, immersion is used in schools to teach the official language. Some companies (like Rosetta Stone) also use the method of immersion in their language programs. From reading the Wikipedia article it seems that learning (a second) language by immersion is mostly used for children and does take quite a long time.
- Are there studies that compare the learning of a language by immersion and the learning by other approaches?
- Is immersion equally useful for adults and for children?
