Abstract
This study suggests that classroom research into students' knowledge construction is
incomplete without data about teachers' knowledge constructions and practice. Teachers'
knowledge related to algebra and teaching algebra were identified and categorised using
three knowledge domains identified by Shulman (1987) as knowledge of epistemology,
pedagogy and pedagogical content of a algebra. Diverse and idiosyncratic examples of
algebra knowledge were articulated by each of the study teachers in relation to the
epistemology and pedagogy of algebra, but examples of pedagogical content knowledge
were seldom easily identified.
