What are the stages of course creation at Duolingo? How is AI involved?
Stage 1: Curriculum design is the first stage of course creation, where curriculum designers plan what to teach and when for any given course. They design the high-level structure of the course, specifying the order of learning objectives so that the course follows the CEFR standard but is also customized for the specific language background of our learners. This stage uses the least of AI and it is mostly prepared by humans.
Stage 2: Raw content creation is the second stage of course creation, where human experts build the “raw” content for each lesson, which later serves as the pool of available material from which specific exercises are created. AI provides some critical support for these experts to do their jobs efficiently. In this stage AI is used more but still the most amount of work is done by humans.
Stage 3: Exercise creation is the third stage of course creation, where experts take the content and create a pool of interactive exercises that we can later show to learners in lessons. Most of the time we use computer algorithms to automatically create exercises from “raw” content, but expert humans also have a part to play in exercise creation. In this stage AI does most of the work, humans do a little bit less work
Stage 4: Lesson personalization is the final stage of course creation, where Duolingo assemble personalized lessons that learners see when they use Duolingo. AI is used to figure out which of those exercises to show to a given learner at a particular time so that the experience is personalized to that learner’s specific needs. In this stage humans do not do anything and everything is created and done by AI.
In conclusion, Duolingo is effective and unique language learning app that uses a variety of AI-powered features to provide users with a personalized and great learning experience. From speech recognition and error detection to personalized lesson creation, Duolingo leverages the power of AI to create an innovative way to learn a new language. Duolingo’s approach to language learning, powered by AI, is a notable example of how technology can be used to make education more accessible and effective.

I love this article! An excellent illustration of how technology may transform education is the usage of AI in Duolingo. The future of language learning appears promising and individualized as AI advances. This is something super important in current times and especially in Poland where we still have a pretty conservative system.
