Group 1: AI's Role in Education - The integration of AI in education is seen as a frontier for innovation, with the potential to enhance personalized learning experiences [2][5]. - Traditional classroom settings often fail to address individual student needs due to large class sizes and uniform teaching methods [3][5]. - AI companions can provide constant feedback and create a judgment-free environment, allowing students to explore and ask questions freely [5][42].
