“…The development of students' digital competences has become an important goal in 21st century education (Griffin, Care, & McGaw, 2012;OECD, 2014;Trist an-L opez & Ylizaliturri-Salcedo, 2014). Recent educational research is therefore concerned with the determinants of students' digital competences on the one hand (Aesaert, van Nijlen, Vanderlinde, & van Braak, 2014;Fraillon, Ainley, Schulz, Friedman, & Gebhardt, 2014;Fraillon, Schulz, & Ainley, 2013;Kikis, Scheuermann, & Villalba, 2009); and teachers' integration of ICT in classrooms on the other hand (Donnelly, McGarr, & O'Reilly, 2011;Hern andez-Ramos, Martínez-Abad, GarcíaPeñalvo, HerreraGarcía, & Rodríguez-Conde, 2014;Sang, Valcke, van Braak, & Tondeur, 2010;Teo, 2011a).…”
