Abstract
The present study investigated effects and gender differences of age at first ICT device use and using ICT in school and out of school on ICT motivation (interest and competence, autonomy, and relat-edness) by using PISA 2018 dataset ( N = 6109 ). The results were as follows: (a) Earlier ICT use and ICT usage for leisure activities were positively correlated with ICT motivation. Especially, ICT usage for leisure activities was found to relate strongly to ICT motivation. (b) Use of ICT for learning out of school was positively correlated with relatedness. (c) A significant gender difference was found in using ICT in school and out of school and ICT motivation.
