Teachers have an important role to play in building a learning society by continuously renewing their own knowledge through self-analysis and feedback. They should experiment with new teaching methods, use multimedia resources, and collaborate with specialists to develop innovative learning materials. Early childhood development is also key, so teachers should inspire creativity in children and teach them to learn independently and from each other. Problem-solving skills and communication skills, which will be important in the 21st century, are also areas teachers can work to improve.
