“…The WST model focuses on the proficiency of teachers (Christensen & Knezek, 2016) and postulates that the teachers` beliefs with regard to digital technologies (will), their technical skills (skill), and the digital equipment available for the teacher (tool) are the most important predictors for technology integration (Knezek et al, 2003;Niederhauser & Lindstrom, 2018). This postulation has been confirmed by many studies showing that those three predictors play a very important role in technology integration (Agyei & Voogt, 2011;Petko, 2012;Farjon et al, 2019;Knezek et al, 2003;Knezek et al, 2000;Knezek & Christensen, 2008Morales Velazquez, 2007;Pozas & Letzel, 2021;Sasota et al, 2021;Sawyerr & Agyei, 2022). In the majority of older studies technology integration was measured as the teachers` familiarity, beliefs, and self-efficacy with regard to digital technologies that can be confounded with the will-and skill-component of the WST model (see for example Agyei & Voogt 2011;Knezek et al, 2003;Knezek & Christensen, 2016).…”
