In countries where the main language is not a world language, students often learn foreign languages in school. However, students are not taught about how to learn a language effectively.
Has any research been done on how effective it is to have a language learning techniques course in school before starting to learn these second languages? Do students who have had a course in language learning techniques perform much better than students who don't?
Such language learning techniques course should include learning about several techniques (e.g. flash cards) that have been shown to be effective by research.
