Around 70 million people have so far signed up to Duolingo – the app which applies the language of computers to help students learn a foreign language for free
Launched in 2012, the app applies computer science to the teaching of English, French, Spanish and German – as well as other languages – by developing a “tree” of skills in which the user goes from one challenge to the next. The method has been curated by examining how thousands of users react to learning one skill, for example verbs, before another, such as adjectives, and finding the most beneficial.
