There are three dimensions of
the teachers’ ICT-competencies (Awouters et al. 2008): (a) the teacher knows what learning activities ICT can be
used in teaching (ICT awareness), (b) the teacher has the necessary skills for using hardware and software (ICT
readiness), and (c) the teacher knows the pedagogical-didactical elements of ICT (ICT drill and practice). ICT
integration in everyday teaching and learning system is defined by three key components (Mishra and Koehler,
according to Jimoyiannis & Komis, 2007: 153): knowledge of pedagogy that is applicable to the specific content;
knowledge of how subject matter is transformed by the application of technology; knowledge of how technology can
support pedagogical goals.
