What is the link between art and creativity? The purpose of this study was to determine the role of art education in creative thinking. A causal-comparative research design was used. Arts and science high school students (N = 162) participated. Results showed that creative thinking in visual arts students in Grade 10 with high scores differed significantly from that in music and science students; however, this difference was not found among students in Grade 11. A main reason for this result in Grade 10 students might be the non-routine problem-solving process in visual arts education, in which artwork production is an important component in creative thinking development. Considering this result, it was concluded that the effect of different education disciplines--"called education department effect"--on creative thinking can be significant.
