The role and use of information and communication technology (ICT) in education has changed profoundly over the last decade. This change is evident at many levels in Abstract 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. Siddiq and Scherer Large-scale Assess Educ (2016) -scale Assess Educ (2016) 4:17 education, for instance, with respect to the availability of ICT resources at schools, the access to internet, and the transition from paper-and-pencil to computer-based exams (Scherer and Siddiq 2015a; Scheuermann and Pedró 2009). Furthermore, students' digital competence has gained substantial attention and is considered to be an important twenty first century skill (Griffin et al. 2012). As a consequence, a first line of research studied the determinants of teachers' integration of ICT into classroom activities (Tondeur et al. 2008), given that the teachers play a key role in developing students' digital skills (Schibeci et al. 2008). Specifically, teachers' computer self-efficacy (CSE) has been identified as one of the most important determinants for teachers' integration of ICT in teaching and learning practices (Kreijns et al. 2013;Mumtaz 2000). Existing research identified positive relations between teachers' CSE and their use ...
