Does Duolingo work? Is Duolingo actually effective for learning a language?

Yes, Duolingo does work. And the answer comes down to learning science.

Duolingo is built on decades of research in psychology, cognitive science, and neuroscience. Instead of asking learners to memorize vocabulary lists or grammar rules, the app uses evidence-based learning techniques that help people remember information longer and use it in real conversations.

Our courses are developed by a team of learning designers, curriculum experts, and learning scientists, including researchers with PhDs in fields like cognitive science, psychology, linguistics, and education.

In this video, Parker (Learning Designer) and Audrey (Learning Scientist) explain the five core learning science principles behind Duolingo:
• Retrieval practice
 • Noticing patterns
 • Spaced repetition
 • The zone of proximal development
 • Communicative competence

You'll also see how features like Practice Hub, Explain My Answer, DuoRadio, Speaking Adventures, and Video Call put these principles into practice.

Whether you're wondering "Does Duolingo work?", "Is Duolingo effective?", "How does Duolingo teach languages?", or "Can Duolingo help you become fluent?", this video explains the science behind the app.
