In this chapter, we explore the dual role of Generative AI in both harnessing and hampering creativity in preservice teacher (PST) education. On one hand, Generative AI (GAI) tools, such as ChatGPT, Adobe Firefly and other programs, offer novel opportunities for enhancing PST creativity. By providing automated assistance in generating ideas, solving problems, and producing artistic content, these technologies can empower PSTs to explore new avenues of expression and innovation. Used effectively, they can foster a conducive environment for creative exploration and self-expression. On the other hand, the widespread adoption of GAI in education raises concerns regarding its potential negative impacts on student and teacher creativity. An overreliance on AI-generated content may inhibit intrinsic motivation, critical thinking skills, and originality, leading to a reduction in creative autonomy and self-efficacy. In this chapter, we share PSTs’ impressions and experiences related to their use of ChatGPT to design creative lesson plans.
