Introduction to Guatemala

• Known for having better Mexican food than Mexico.

Socioeconomic Context

• Guatemala is a very poor country.
• Education often creates inequality due to financial disparities:
  • Wealthy individuals can afford better education.
  • Poorer individuals receive minimal education, perpetuating poverty.

Personal Experience & Motivation

• Speaker received a quality education due to being an only child and mother’s prioritization.
• Achieved a PhD in computer science.
• Inspired to provide equal access to education globally.

Formation of Duolingo

• Initial focus: teach one subject effectively before expanding.
• Decision to teach foreign languages due to:
  • Huge global audience (2 billion learners, mostly English).
  • Direct income benefits from learning English, unlike indirect benefits from subjects like math.
• Mobile access strategy:
  • Mobile phones allow reach to a wide audience.
  • Named the platform "Duolingo."

Duolingo’s Business Model

• Freemium model:
  • Free access with ads.
  • Subscription option to remove ads.
• Wealth redistribution:
  • Wealthier individuals from richer countries pay for the education of those in poorer countries.

Challenges of Mobile Education

• Competing with addictive apps (e.g., TikTok, Instagram) on smartphones.
• Strategy: make educational content as engaging as possible.

Engagement Techniques

• Streaks: Encourage daily usage by tracking consecutive days of use.
  • Over 3 million users with streaks longer than 365 days.
  • Longest streaks: Japan; Shortest streaks: Latin America.
• Notifications:
  • Sophisticated AI determines optimal timing.
  • Stops after 7 days of inactivity; passive-aggressive reminders increase engagement.
• Memes & Cultural Impact:
  • Duolingo's green owl mascot leads to internet memes, increasing brand recognition.

Educational Impact

• Duolingo’s reach surpasses traditional language education institutions in many countries.
• Aim: expand similar techniques to other educational subjects, especially those learned through repetition (e.g., math).

Conclusion

• Vision for the future where screen time delivers high-quality education universally.
• Encouragement to complete language lessons regularly.

Q&A

• Applicability of Duolingo’s techniques to other subjects:
  • Repetitive learning subjects like math can be gamified.
