I have been teaching in elementary school grades 1-4 for 17 years, sometimes as a homeroom teacher and other times as an after-school teacher. Currently, I work as an after-school teacher, which provides ample opportunities not only for mastering basic knowledge but also for fostering children's creativity and developing skills such as problem-solving, critical thinking, and innovation, all of which are essential for meeting the challenges of 21st-century life. In my work, I focus on creating materials and activities that support continuous renewal, as this is the only way we can progress effectively and stay on track.
