Pedagogical content knowledge is understood as the “blending of content and pedagogy”[13] that guides the organization, representation and adaptation of the material for all learners through instruction. This concept goes beyond the consideration of the content knowledge as isolated from the pedagogical knowledge teachers must possess to effectively cater to the needs of their students. In order to illustrate how pedagogical content knowledge operates in reference to a specific knowledge domain, we can turn to the field of second language teaching.
