This study examines whether age difference affects children's performance on writing with the computer and writing with the pencil and whether there is a relationship between the two writing skills. For this study, 61children aged 3 to 5 were interviewed individually and their computer and pencil writing samples were collected. Computer writing samples were analyzed on the basis of "Level of Children's Computer writing(Yang & Kim, 2001); pencil writing samples were analyzed on the basis of "Six Categories of Writing(Sulzby, 1990). The analysis showed that children on different age groups displayed different levels of competency in the computer writing and pencil writing skills and that the competency developed with the advancement in age. It also showed that there was a statistically meaningful correlationship between computer and pencil writing in the case of 4-year-old children.
