Pedagogical content knowledge (PCK) of science teachers based on content representation (CoRe)

Pedagogical Content Knowledge (PCK) has been one of the chief frameworks that widely employed by educators and researchers in order to examine and develop teachers knowledge of integrating content into the right pedagogy. In this article authors purposes to describe PCK of science teachers using an instrument developed by John Loughran, well known as Content Representation (CoRe). A core is constructed by asking teachers to identify "the big ideas" associated with teaching a topic to students. Participants were science teachers from a secondary school and have different ages from 21 until 34 years old. They were completed Content Representation to gain the data about their ability in PCK. Our results reveal that the teachers have different knowledge of PCK. Teachers knowledge of their PCK is related to working experience and professional development.
