Critical thinking sits at the heart of higher education, yet many learning materials still encourage passive consumption rather than active reasoning. This project introduces error-seeded AI assignments, a teaching strategy that transforms AI-generated content into interactive learning tools. Using platforms such as ChatGPT, Descript, or Synthesia, instructors create short texts, videos, or podcasts intentionally embedded with various errors. Students then identify, explain, and correct these mistakes, turning AI into a catalyst for reflection and analysis. Adaptable across disciplines, this approach promotes deeper understanding, curiosity, and engagement while redefining how AI can be used not just to deliver information, but to develop thinkers. #CriticalThinking#CreativePedagogy#AIContentCreation
