Lịch sử hình thành của duolingo
Duolingo started as an idea from Luis von Ahn, who wanted to create a free
language-learning platform, unlike expensive courses like Rosetta Stone. He
teamed up with his PhD student, Severin Hacker, to develop the platform in 2009.
By 2011, Duolingo launched its beta version and was officially released to the
public in 2012 with support for multiple languages.
From 2013 to 2017, Duolingo grew quickly by launching its mobile app on iOS
and Android, attracting millions of users. In 2014, it introduced Duolingo for
Schools to help teachers with language lessons. In 2016, Duolingo Incubator was
launched, allowing the community to contribute to new courses.
From 2018 until now, Duolingo has expanded and become even more successful.
In 2018, it added features like Stories, Podcasts, and Duolingo Plus (the ad-free
version). In 2021, Duolingo officially went public on the Nasdaq stock exchange
under the symbol DUOL. Today, Duolingo has over 500 million users, supports
more than 40 languages, and is one of the most popular language-learning apps in
the world.

cost. The app is available on both mobile and desktop, making it convenient to
study anytime, anywhere.
Gamified Learning
Lessons are designed like a game, making learning fun and engaging. The point

Supports Multiple Languages
Duolingo offers over 40 languages, including popular ones like English, Spanish,
French, and Japanese, as well as rare languages like Scottish Gaelic, Esperanto,
and Hawaiian.

It is designed for both beginners and advanced learners who want to review and
improve their skills. The placement test helps users start at the right level.
Comprehensive Practice
Lessons cover vocabulary, grammar, listening, speaking, reading, and writing. The
"Duolingo Stories" feature helps improve reading and listening skills in real-life
contexts.
Flexible and Stress-Free Learning
There is no time limit, so users can learn at their own pace. Short lessons take only
a few minutes each day, making it easier to stay consistent.
Upgraded Version (Duolingo Super)
The premium version removes ads, offers advanced review features, and provides
detailed progress tracking.
Những khuyết điểm của duolingo Lack of In-Depth Grammar Teaching
Lessons focus mainly on vocabulary and sentence patterns but do not
explain grammar in detail.
Learners may struggle to apply grammar correctly in real-life situations.
Not Suitable for Advanced Communication
Duolingo helps improve reading, writing, and listening, but there are few
opportunities to practice real conversations.
Pronunciation exercises are basic and do not provide detailed feedback on
correct pronunciation.
Content May Feel Unnatural
Some translations on Duolingo can be unrealistic or uncommon in daily life.
Sentence structures may differ from how native speakers usually
communicate.
No Personalized Guidance
The app uses AI to adjust lessons, but there are no live teachers to guide
learners.
Users cannot ask questions or receive detailed feedback like in a traditional
classroom.
Ads in the Free Version
Free users must watch ads after each lesson, which can interrupt the learning
experience.
The Super version (paid) removes ads and offers advanced review features.
Gamification System Can Be Distracting
Some users may focus more on maintaining their streaks or earning points
rather than actual learning.
The game-based approach may not be suitable for everyone.
