Abstract The emergence of Generative Artificial Intelligence (AI) is transforming the field of education by introducing innovative approaches to teaching and learning. In Teacher Education Institutions, Generative AI tools such as ChatGPT and Google Gemini are increasingly being used for lesson planning, content generation, academic writing, assessment preparation, and personalized learning support. The present study examines the impact of Generative AI on teaching and learning in Teacher Education Institutions, with special reference to the Indian educational context. The study focuses on understanding the level of awareness, usage patterns, benefits, and challenges associated with Generative AI among teacher educators and student teachers. The study adopts a descriptive research design and uses both primary and secondary data sources. Primary data may be collected through questionnaires and surveys among teacher educators and student teachers. The study explores how Generative AI influences teaching effectiveness, student engagement, creativity, research activities, and academic performance. It also highlights major concerns related to academic integrity, plagiarism, ethical issues, over dependence on technology, and lack of AI literacy. The findings of the study are expected to reveal that Generative AI has significant potential to enhance educational practices by improving access to information, supporting innovative teaching methods, and promoting personalized learning experiences. However, the study also emphasizes the need for proper guidelines, ethical usage policies, and AI training programs for educators and students to ensure responsible integration of AI technologies in teacher education. The study concludes that Generative AI can become an effective educational tool when used appropriately and ethically in Teacher Education Institutions.
