Development Strategies and Practical Insights of Teachers' Artificial Intelligence Competence

Artificial Intelligence (AI) in education not only changes the education model but also transforms the role of teachers from traditional "knowledge transmitters" to "learning guides" and "skills trainers". This transformation underscores the importance of teachers in leveraging AI for educational enhancement and professional growth, highlighting the need for improved AI competencies. We adhere to human-centered principles and follow ethical and responsible AI ethical standards to ensure that technology truly serves education. Through a literature review from an international perspective, this study examines global trends in AI educational practices, comparing policies, curricula, and research across Asia, Europe, and Africa. This comparison facilitates a deep understanding of AI's application and challenges within various cultural and educational settings, offering insights into enhancing teacher's AI competencies. The paper concludes by suggesting a detailed strategy for bolstering teachers' AI skills, employing a stepwise approach to foster professional development and elevate educational quality in the AI era while providing guidance for teachers to use AI critically and transformatively.
