He moved to Pittsburgh to study at Carnegie Mellon University where he co-founded Duolingo with Luis von Ahn in 2009.[6] He received his BS in Computer Science from ETH Zurich in 2006 and his PhD in Computer Science from Carnegie Mellon University in 2014.[7] The Founding of DuolingoInitially, Hacker and his former graduate advisor, Luis von Ahn, wanted to develop an application that could translate internet sites, so that it would be accessible for non-English speakers. They felt that automated translation software wasn't as effective as using the skills and knowledge of bilingual speakers.[8] During Hacker's doctoral studies, Duolingo became a by-product of this idea, or "happy mistake."[9] Hacker's goal for Duolingo was to make it "100% free" so the most disadvantaged person with an internet connection would still have access to it.[8] DuolingoHacker and his team of PhD students used machine learning to personalize Duolingo to each user. Specifically, they wanted to predict what language concepts the user was on the verge of forgetting. In 2012, a study by American universities showed that spending 34 hours of learning on Duolingo was equivalent to a full-semester of a college language course. Hacker and von Ahn still intend to use Duolingo to get closer to their original idea. They have recently started selling translations, such as to the Spanish tech news group of CNN.[10] Retention PhilosophyThere are two parts to Hacker's "Retention Philosophy": learning should be fun and motivation should remain high.[10] Through Duolingo, Hacker wants users to have the option to increase their 'stay-tuned quota' which involves adjusting the learning time and difficulty of the course. Another idea derived from Hacker's philosophy was to apply gamification to Duolingo. This was to apply game elements and principles instead of classroom learning tools to the course.[10] Awards and Honors
