Duolingo Lessons

Duolingo offers various lessons and activities in unique ways. Students will learn using different approaches like stories, audio, video, etc. Below are the types of lessons Duolingo provides, showing how it utilizes listening exercises, flashcards, and multiple-choice questions for learners.

Skill Tree of Lessons (Modules):

One of the best and most compelling features of Duolingo is the skill tree or language tree. Each language course consists of various skills that cover certain topics. Those topics teach learners English vocabulary and grammar with a broad scope of languages. Also, each skill set has five levels that help the users practice, providing various activities and exercises. Duolingo’s skill tree of lessons is more like an organized progression of a course’s skill depending on the difficulty level.

Duolingo Skill Tree

Every level unlocks new lessons regarding each module. The higher the level, the more challenging the exercises are. And as you progress, unlocking new skills will help you learn English more.

Here are some topics covered in the skill tree of lessons.

  • Basics 1. It is one of the most important skills in the tree, especially if you are just starting to learn the language. It teaches the basics of English and provides lessons consisting of simple words such as man, woman, boy, and girl. In addition, Basics 1 serves as a primary lesson to introduce English before taking up the language tree.
  • Phrases. If you master Basics 1, you will progress to the next skill in the language tree, which is the Phrases. This skill contains sentences and their translations. It will help you learn some full phrases in a certain language. Phrases also help you practice your pronunciation and skills in putting words into a sentence.
  • Animals. One of the most fun skills in the language tree is the Animals. This skill teaches you the translation of an animal’s name into different languages. What’s more entertaining than knowing animal names in English, French, Romanian, and many more? Plus, Animals skill comes with audio pronunciations and related words.
  • Food. This skill is probably the best one on the language tree for food lovers. Imagine going to an American, Japanese, French, or Italian restaurant, knowing the food you want to order. The Food skill contains lessons to help you translate the name of the food to whatever language you want with audio pronunciations.
  • Family. If Duolingo can help you learn the names of animals and food, it also offers Family skills. You can learn to call your parents, grandparents, siblings, and even relatives, in different languages. Plus, this skill contains lessons and challenges with audio guidance.
  • Transport. Duolingo also has a thing for people who love to travel. Transport is a perfect skill in the language tree if you want to learn words, phrases, and sentences about modes of transportation like cars, boats, and airplanes. Plus, it consists of lessons that will help you a lot when traveling to different countries.
  • Shopping. After you master the language tree, you can purchase certain items to add new skills. You can shop for anything that can enhance your English. If you are really motivated in learning languages, a few bucks will surely not bother you.
  • School. The Duolingo school is an excellent feature that allows teachers to view their students’ skill trees easily. Teachers need them to keep track of how well their students are doing and their progress.


Duolingo Stories

Duolingo Stories is one of the platform’s best features. This section focuses on developing the users’ English reading and listening skills. It provides fun dialogues and conversations that are fitted to your level. In other words, it contains short stories with an audio presentation that you can listen to while reading.

This feature also aims to develop the learners’ vocabulary with lessons like filling in the blanks in conversations. However, Duolingo Stories are only available for Portuguese, Spanish, and Chinese speakers who want to learn English. But, the company is constantly updating to add more languages.

If you are interested in Duolingo stories, you have to unlock them first. You have to earn ten crowns or reach Checkpoint 1 on your Duolingo tree to unlock this section. Each set of stories is locked, except the first one. So, you need to complete all the stories inside that set before jumping into the next one. In addition, stories also get more difficult as you go further, resulting in more learning.

Audio Lessons

Duolingo Audio Lessons

After you learn some English words, phrases, and sentences, you want to improve your vocabulary and enhance your listening and speaking skills. Well, Duolingo offers their Audio Lessons feature that aims to strengthen your English conversation skills.

Duolingo’s Audio Lessons consist of realistic scenarios and conversations. Plus, you will meet two hosts who will guide you throughout your journey in listening, pronouncing, and speaking English independently. In addition, the topics will give you some important phrases on how to be polite and proper usage of the words “um” and “so.” The goal is to make learners independent in listening and speaking and use it in a normal conversation.

Gamification on Duolingo

A prime reason why Duolingo is attracting more users is the gamification. It’s a system where game-based elements are added to be more engaging to the learners.

If you are a competitive learner, Duolingo must be the best platform for you. It features Crown levels, rankings, and achievements. In each level you finish, you are given a set of crowns. The more difficult your level is, the more crowns you get. The Crown level feature ranks your development with Duolingo on how good you are doing and how well you are now.

Final Thoughts on Duolingo for Learning English

Duolingo is available on all platforms (mobile and desktop), making it accessible to most users. The courses’ structure and gamification make learning English sustainable and fun on the app. The Stories section that has real-life conversational scenarios helps you put all your practice into action. Most importantly, it’s free, which is a huge driver for its massive downloads.

Perhaps, the major drawback could be that the quality of your experience depends on how good your internet or mobile connections are. The Duolingo Plus users have the advantage of being able to download the lessons for offline access.

One of the most widely discussed drawbacks is their three-hearts system that forces students to retake the lesson if three mistakes are made. If you scour through online conversations on Reddit of Facebook Groups — this is the most widely heard negative feedback.

However, for a free app with immersive and extensive features — the positives far outweigh the drawbacks. We strongly encourage Duolingo as an app that you can start using today to learn and improve your English.

So, what are you waiting for? Use Duolingo now and have fun while learning English. You can download Duolingo on either the Google Play Store or Apple Store.

Additional FAQs

Can I learn English from the Duolingo app?

Yes, you can definitely learn English using the Duolingo app! Duolingo offers interactive lessons that cover reading, writing, listening, and speaking skills, making it a comprehensive tool for language learning. With its gamified approach and personalized learning experience, Duolingo has helped millions of users around the world improve their English proficiency.

Can you become fluent in English with Duolingo?

While Duolingo is a valuable tool for language learning, achieving fluency solely through the app may be challenging. Fluency encompasses not just vocabulary and grammar but also cultural nuances, idiomatic expressions, and conversational skills. Duolingo provides a strong foundation and can help you build vocabulary and grammar skills, but fluency typically requires immersion experiences, regular practice with native speakers, and exposure to authentic language materials such as books, videos, and conversations. Therefore, while Duolingo can be an excellent supplement to your language learning journey, becoming truly fluent in English may require additional resources and experiences.

How many hours on Duolingo to become fluent?

The number of hours required to become fluent in a language through Duolingo or any other method can vary significantly from person to person. Factors such as prior language learning experience, natural aptitude for language acquisition, consistency of practice, and the complexity of the language itself all play crucial roles. While some individuals might reach a proficient level with just a few hundred hours of practice, others may need significantly more time and effort. Ultimately, the key is consistent practice, immersion experiences, and exposure to real-life language usage beyond the confines of any single learning platform.

Can Duolingo get you to B2?

While Duolingo can be a valuable tool for language learning, reaching a B2 level of proficiency solely through the app may be challenging for most learners. The Common European Framework of Reference for Languages (CEFR) describes the B2 level as an intermediate level where learners can understand the main ideas of complex text, interact with native speakers with fluency and spontaneity, produce clear, detailed text on a wide range of subjects, and express opinions on various topics.

While Duolingo covers vocabulary, grammar, and basic language skills, achieving B2 proficiency typically requires a more comprehensive approach, including exposure to authentic language materials, immersive experiences, speaking practice with native speakers, and cultural understanding. Therefore, while Duolingo can certainly help you progress in your language learning journey, reaching a B2 level of proficiency may require supplemental resources and experiences.
