Over the years, I’ve worked with countless students learning Spanish, each with their own unique challenges and motivations. Some loved the structure of a traditional classroom; others needed something more interactive, more engaging, more gamified. That’s why, in 2018, I started using Duolingo Classroom with my high school Spanish students.
At first, it was simply a way to give students consistent exposure to Spanish outside of class. Each week, they were required to earn a set number of points as homework. But as I began preparing students for the Mississippi Seal of Biliteracy examinations, I saw how valuable regular practice could be in reinforcing vocabulary, sharpening reading skills, and keeping the language fresh in their minds.
Of course, students needed an extra incentive—so I turned it into a friendly competition. Each nine weeks, I’d issue a challenge: Whoever earned the most points would win a $20 gift card to a local store or restaurant of their choice. Some students thrived on the challenge, pushing themselves to do more than the required points, while others simply appreciated the low-pressure way to practice Spanish beyond our daily lessons.
Their experiences—and my observations as a teacher—gave me a new perspective on Duolingo. It’s an incredible tool, but like any tool, it has its strengths and its limits.
What Duolingo Gets Right
Seeing my students engage with Duolingo over the years, I’ve come to appreciate the things the app does well:
✅ All Four Language Skills in One Place – Unlike many apps, Duolingo includes reading, writing, listening, and speaking in each lesson. Even though the speaking practice is limited, it’s still a great starting point.
✅ It Makes Learning Feel Like a Game – Students who weren’t motivated by traditional homework suddenly cared about streaks, XP, and leaderboards. The friend quests and challenges helped them stay engaged week after week.
✅ It’s Free & Accessible – One of my favorite things about Duolingo is its commitment to keeping language learning free. The paid version removes ads and adds features, but all the lessons are still available to free users.
✅ It Builds Consistency – Even if students weren’t actively thinking about Spanish throughout the day, logging in to Duolingo gave them a reason to interact with the language daily.
✅ The Community Keeps You Motivated – Learning a language can be overwhelming, but Duolingo’s community helps learners celebrate progress together instead of feeling isolated.
For these reasons, I loved using Duolingo in my classroom. But I also saw firsthand where it falls short.
Where Duolingo Falls Short
Despite all its strengths, Duolingo alone won’t make you fluent.
❌ It’s Not Enough for Speaking & Conversation – Clicking through sentences and repeating isolated phrases isn’t the same as having a real conversation. My students still needed real-life speaking practice.
❌ It Doesn’t Explain Grammar Well – Duolingo helps learners recognize patterns, but it doesn’t explain them in a way that makes the language click. This was especially frustrating for students preparing for higher-level exams.
❌ Some Sentences Are Unnatural – My students got a kick out of the weird sentences Duolingo sometimes throws in. But memorizing, “The turtle reads the newspaper,” wasn’t exactly useful for real-world conversations.
❌ It Lacks Cultural & Regional Context – Language isn’t just vocabulary and grammar—it’s expressions, dialects, and culture. Duolingo doesn’t expose learners to the way native speakers actually talk.
For these reasons, I never relied on Duolingo alone to teach Spanish in my classroom. It was a tool, not a complete solution.
How Other Language Apps Compare
After seeing my students’ experiences with Duolingo, I decided to explore other language learning apps—both for my students and for my own language-learning journey. Here’s how they stack up:
🔹 Busuu (Paid Version)
✅ Structured like a real course—includes grammar lessons and explanations.
✅ Interactive community feature where users correct each other’s writing.
❌ Not as engaging as Duolingo—felt more like traditional studying.
❌ Correcting others took time away from learning my own target language.
🔹 Best For: People who want structured lessons and grammar explanations.
🔹 Pimsleur
✅ Best for pronunciation & speaking practice.
✅ Focuses on real conversational skills.
❌ Expensive compared to other apps.
❌ No reading or writing practice—it’s all audio-based.
🔹 Best For: Speaking practice—great for people preparing to travel.
🔹 HelloTalk (AI version)
✅ Lets you practice chatting with AI-based language partners.
✅ Gives feedback on your writing.
❌ Not structured—better as a supplement.
🔹 Best For: Casual text-based practice for intermediate learners.
🔹 Rosetta Stone
✅ Full immersion—teaches you without using English.
✅ Good for visual learners.
❌ Very expensive compared to other apps.
🔹 Best For: A structured, immersive experience (but only if you’re willing to pay).
🔹 Babbel
✅ Provides grammar explanations that Duolingo lacks.
✅ Covers real-life conversations.
❌ Feels like a traditional classroom course (not as fun).
🔹 Best For: People who need structured grammar lessons.
🔹 Clozemaster
✅ Uses real sentences instead of random vocabulary lists.
✅ Gamified like Duolingo but focused on grammar & vocabulary.
❌ Not good for beginners—you need a solid foundation first.
🔹 Best For: People who already know the basics and want to reinforce grammar and vocab.
Final Thoughts: Can Duolingo Make You Fluent?
No single app will make you fluent. Language learning requires real-world experience, conversation practice, and lifelong learning.
Apps like Duolingo are fantastic for building a foundation, but they’re just one piece of the puzzle. Fluency comes from:
✔️ Speaking and interacting with real people.
✔️ Listening to music, podcasts, and native conversations.
✔️ Reading beyond short sentences—books, articles, and more.
✔️ Studying grammar and learning how the language actually works.
Even as a fluent Spanish speaker, I’m constantly learning new words, brushing up on forgotten vocabulary, and refining my skills. Language learning never stops.
That’s why I love Duolingo—it keeps learning fun and consistent—but if you’re serious about fluency, you have to take learning beyond the app.
