The purposes of this study were to develop art educational skills of the college students in the course of early childhood education, and preschool children's creativity through "as if" drawing activities. The students made the teaching plans of "as if" drawing activity using Persona/Scenario method. Today, commercial artists use the Persona/Scenario method to produce user-centered design. The findings were that (1) the students acquired higher art educational skills through experiences that made the teaching plans of "as if" drawing using Persona/Scenario method. (2) Preschool children showed creativities in "as if" drawing activities when the college students carried out their teaching plans in preschools.
