Research-backed approaches to language acquisition
Review vocabulary at optimal intervals using Anki or built-in SRS. The most effective method for long-term vocabulary retention — 200-400% improvement over traditional study.
Immerse yourself in content slightly above your level — podcasts, YouTube, Netflix with subtitles. Stephen Krashen's theory: we acquire language when we understand messages.
Start speaking from day one — even imperfectly. italki tutors from $5/hour. Language exchange apps (HelloTalk, Tandem). The discomfort of speaking is where real acquisition happens.
Read graded readers and then native material. LingQ platform tracks unknown words. Even 20 minutes of daily reading dramatically improves grammar intuition and vocabulary.
Write daily in your target language and get corrections from native speakers (Busuu, Lang-8, HelloTalk). Writing forces you to produce language, not just recognize it.
Change your phone language, watch shows in target language (Netflix language learning extension), listen to music, follow social media accounts. Create an immersive environment at home.
