AI chatbots in mental health – helpful tools or risky replacements? — Video-based ESL lesson

In this lesson, intermediate to advanced ESL learners will explore the current developments and concerns surrounding AI in mental health therapy.

By the end of this 60 -minute session, students will confidently discuss the benefits and limitations of AI therapy chatbots, use key vocabulary in context, and engage in debates about the role of technology versus human connection in mental health care.

Having students watch the video before class will greatly reduce in-class time. Through interactive activities like discussions, comprehension tasks, and role-play, students will build their language skills while developing critical thinking about the future of mental health support. Let’s get started by examining the rise of AI therapists.

  4. Discuss answers as a class, encouraging students to use the new vocabulary

Speaking activity (15 minutes)

Activity: Group discussion – AI vs human therapists

  1. Divide students into small groups
  2. Assign each group a scenario (e.g., someone with mild stress, someone with severe depression, someone who cannot afford therapy)
  3. Ask groups to discuss:
     • Would AI therapy be helpful in this situation? Why or why not?
     • What are the advantages and risks? (Use vocabulary like accessibility, empathy, validation, privacy)
  4. Each group presents their ideas to the class, using at least 3 vocabulary words

     • Pros (e.g., accessibility, low cost, always available)
     • Cons (e.g., lack of empathy, privacy risks, solution-focused only)
     • One example sentence using vocabulary for each point
  3. Groups present their charts to the class, explaining their main ideas in 1-2 minutes

Wrap-up (5-10 minutes)

Activity: Reflection and quick quiz

• Objective: Review key concepts and assess understanding
• Instructions:
  1. Conduct a quick oral quiz with questions like:
     • What word means “accepting someone’s feelings as real”? (Validation)
