Hello~ I am Teacher Ttokji, a professional coding instructor. I conduct Play Coding and 3D Pen classes at various educational institutions, including early childhood education centers and elementary school after-school programs. I conduct my classes in a way that expands thinking through stories and allows students to explore those expanded ideas through play. Through this approach, children participate in the class easily and enjoyably. It is a class where they can think for themselves and engage in creative activities, rather than just simple crafting.
