Hello. I am currently working as an English education expert and run the YouTube channel <Joyful Elementary English>. Originally, I worked at a publishing company called Cheonjae Education for over 14 years. There, I primarily focused on planning and editing English textbooks. That is why I have a very detailed understanding of the elementary, middle, and high school curriculums for our children. Why is such experience important? Because only by properly grasping children's cognitive development and the level of English in public education can we better understand our children's minds. There are many teachers who teach English well, but "Teacher Genie" is the only one who can guide children by grasping the curriculum and cognitive levels in this way. My published works include <Let's Go Phonics 1, 2, 3, 4>, <Korean and English Reading Methods Every Elementary Mom Must Know>, and <Have You Chewed Away Your English Textbook?>. If you are a mother who wants to meticulously ensure your child's English learning is grade-specific and that nothing is missed, please remember Teacher Genie.
