Engage your students with the addictive psychology behind the world’s most popular learning app!
This dynamic, ready-to-use lesson (B1-B2+ level) is built around the viral TED Talk by Duolingo co-founder Luis von Ahn. Students won’t just watch a video – they’ll deconstruct the secret recipe that makes a language-learning app as compelling as social media.
Students dive deep into the intersection of technology, psychology, and education. They analyze Duolingo‘s freemium model as a tool for global access, dissect its gamification techniques (streaks, notifications, mascots), and debate the ethics of using “addictive” design for a positive goal. The central question drives the lesson: How can we make meaningful learning as engaging as our favorite apps?
Skills Developed:
- Listening Comprehension: Targeted tasks guide students to extract key ideas, arguments, and details from an authentic, fast-paced talk.
- Critical Thinking & Discussion: Students evaluate business models, discuss motivation, and apply concepts to new contexts through structured debates and personal reflection.
- Vocabulary Building: Focus on high-impact collocations and topic-specific lexicon related to tech, business, and education (e.g., increase income potential, sophisticated AI, internal motivation).
- Creative Synthesis: A unique “Design Your App” extension activity challenges students to apply the lesson’s principles by pitching their own gamified solution to a learning problem.
