This study was to examine the relations parenting styles, media use types(education, entertainment), and preschooler's behavior problems. We analyzed the data from the 6th year Korean Children Panel Study(KCPS), including 1,662 families with 5-year-old children. Structural equation modeling was used for data analysis. The results of this study were as follows. First, parental warmth and control were associated with the shorter media usage time for playing. But parental warmth and control had insignificant impacts on media usage time for education. Second, media usage time for education was related to a lower likelihood of depression/anxiety and aggression. On the other hand, media usage time for entertainment was associated with a higher levels of attention problems and aggression. Based on the study findings, desired teaching methods according to preschooler' media usage types for parents and teachers were discussed.
