As AI tools become increasingly prevalent in education, the challenge for instructors is moving beyond AI as a mere novelty and leveraging it as a meaningful tool for writing fluency and discussion. This hands-on workshop will introduce educators to an AI chatbot-based approach designed to support EFL students in brainstorming, developing ideas, and refining their writing through structured peer-like AI interactions. Drawing from a classroom-tested framework, this session will demonstrate how chatbots can help reduce student hesitation, enhance fluency, and provide low-stakes opportunities for idea generation. Attendees will engage in a live demonstration, explore effective prompting strategies, and gain access to a customizable AI chatbot template they can use in their own classrooms. The workshop will also address potential pitfalls, including over-reliance on AI-generated content and strategies for maintaining student agency. Participants will leave with practical, research-informed strategies to integrate AI in ways that align with communicative language teaching and enhance student engagement in writing courses.
