Duolingo: Improving Language Learning and Assessment with Data
Duolingo is a language education platform that teaches 20 languages to more than 150 million students worldwide. Our free flagship learning app is the #1 way to learn a language online, and is the most-downloaded education app for both Android and iOS devices. In this talk, I will describe the Duolingo system and several of our empirical research projects to date, which combine machine learning with computational linguistics and psychometrics to improve learning, engagement, and even language proficiency assessment through our products.
