Duolingo
About
Duolingo is a language-learning educational application for web and mobile devices. The platform assesses users through a variety of tests, using writing, reading comprehension, and speech, which become increase in difficulty depending on the user's proficiency.
History
Work on Duolingo began at the end of 2009.[1] Carnegie Mellon University computer science professor Luis von Ahn, the inventor of CAPTCHA, and Severin Hacker, a graduate student, wanted to create an app that would teach people a new language but also translate simple phrases around the internet.[2] Ahn also wanted to create a free way for people around the world to learn new languages, something that was very expensive in his home country of Guatemala.[3] In exchange for the user's translations, Duolingo has remained free for users.
Funded by a MacArthur fellowship[4] and a grant from the National Science Foundation,[5] Duolingo launched a public beta on November 30th, 2011 with a waiting list of more than 300,000, before releasing to the general public on June 19th, 2012. The app hit the iOS App Store on November 13th and the Google Play Store on May 29th, 2013.
Features
Duolingo offers courses in more than 20 languages. The app assesses student proficiency through more than 68 courses, which ask the user to read, listen, and speak different languages.
To keep students engaged, the developers gamified Duolingo, encouraging users through a streak count, which motivates users by tallying how many days in a row they have taken classes, experience points, and hearts -- if all hearts are depleted in a session, the user must retake the lesson.
In Duolingo, users gain "lingot, "a portmanteau of lingo and ingot," (now called Gems) for good performance. Lingot allows users to purchase different items in the game.
As of May 2017, Duolingo offers 23 course for users who know English. They include:
