The pedagogical content knowledge concept was extended by adding the technology component to it and thus TPCK was used to describe teachers’ body of knowledge in terms of how they made ‘intelligent pedagogical uses oftechnology’ (Koehler, Mishra & Yahya, 2007, p. 741). The TPCK acronym was renamed TPACK to make it easier to remember and to form a more integrated whole for the three kinds of knowledge addressed: technology, pedagogy, and content (Thompson & Mishra, 2007-2008, as cited in Schmidt et al., 2009, p. 123).
