Globalization refers to the increased interconnectedness between countries and regions through fast flows of goods, services, finance, people and ideas across international borders. Global education aims to help students understand other cultures and viewpoints to become responsible global citizens. It focuses on cultural diversity, human rights, and sustainability. For the 21st century, teachers need to cultivate global competence in students by developing their critical thinking, cultural awareness, empathy, and ability to solve problems collaboratively with people from different backgrounds. Infusing real-world contexts and global issues into learning engages students and helps prepare them for an interconnected world.
