This chapter describes the possibilities and challenges of using generative AI in teacher education from the
perspective of classroom researchers. We followed these steps in the chapter: select a lesson, analyze the lesson, use
the results of the lesson analysis to create prompts in generative AI, ask the generative AI to make a lesson plan
using the prompt, and discuss the possibilities and limitations of the lesson plan. Considering that teachers work
long hours and are inevitably involved in planning lessons, it is essential to focus on creating lesson plans, a part of
lesson preparation. We will make clear whether there is potential for teachers to interact with generative AI when
creating lesson plans and whether there is potential for the created lesson plans to be accepted into the school and
teacher culture. If it were possible to create lesson plans using generative AI, or if it were possible to create
instructional plans that would suggest lesson content, it would contribute to reducing the burden on teachers even if
it does not directly contribute to improving their work style.
