Teachers’ integration of information and communication technology (ICT) has been widely studied, given that digital competence is considered to be a crucial outcome of twenty first century education. In this context, research highlighted teachers’ computer self-efficacy (CSE) as one of the most important determinants of their ICT integration into teaching practices. Whereas previous research mainly focused on the relation between CSE and ICT integration from a frequency-based point of view, recent research suggests to investigate this relation using more qualitative measures of ICT integration such as the degree to which teachers emphasize developing students’ digital information and communication skills (TEDDICS). Consequently, the present study investigates the relations between these two constructs: teachers’ emphasis on developing students’ digital skills and their computer self-efficacy, taking into account the moderating roles of age and gender. We used a representative sample of 1071 Norwegian secondary school teachers who participated in the international computer and information literacy study (ICILS) in 2013. Our results provide evidence on the positive relation between CSE and TEDDICS. Furthermore, age positively moderated this relation between some factors of the two constructs, indicating that computer self-efficacy plays an even more important role for teachers of higher age in the context of emphasizing ICT skills in classrooms. The unique effect of gender was present for one correlation between CSE and TEDDICS, indicating that moderation by gender was apparent to a limited extent, and related to use of computers for instructional purposes. The interaction between age and gender did not reveal significant moderation effects. We discuss these results in light of the potential consequences for teacher training.
