Globalization has had a significant impact on various aspects of life, including education, by presenting new opportunities and challenges. This research aims to analyze the reorientation of the role of teachers in the era of globalization, especially in integrating technology, instilling social values, and preparing students to face the skills needs of the 21st century. This research uses a qualitative approach based on literature studies to explore the strategies and challenges faced by teachers in supporting educational transformation relevant to the dynamics of globalization. The research results show that teachers need to adopt a new paradigm that positions them as facilitators, innovators and character models in the learning process. Technology integration strategies, such as the use of interactive learning media, are the key to increasing student engagement. Apart from that, systematic values education and multicultural education are considered important for building students' character that is inclusive, tolerant and based on local values. 21st century competencies, including critical thinking, collaboration, creativity, and digital literacy, must be integrated into the learning process through innovative approaches, such as project-based or problem-based learning. Challenges faced include the digital divide, limited resources in remote areas, and the need for ongoing teacher professional development. This research recommends collaboration between government, educational institutions and society to support the role of teachers in facing the demands of globalization. These findings contribute to the development of educational policies and learning strategies oriented towards the formation of future generations who are academically competent and have strong moral character.
