The purpose of this study aims to provide basic research data about Korean elementary students’ digital literacy activities. The 10,111 3rd to 6th grade students participated in this survey. The students spent more time in using smart phones than computers, and they used both devices more during weekends than weekdays. On a daily basis, students’ digital literacy activities were ordered: watching videos was the highest activities, and the next frequent activities were instant messaging, gaming, and information searching. Nearly half students did digital activities for recreational purpose. Only less than 5% students participated in the digital activities for social purposes. There were response gaps between 3rd and 4th grade students and 5th and 6th ones, and between big cities and other regions. However, gender differences were insignificant or negligible. The findings from this study need to be considered because the differences of digital literacy environments and activities may influence students’ academic achievements and other factors.
