This study reconsiders the notion of pedagogy for pedagogical content knowledge (PCK) in the context of teaching mathematics. The perspectives of critical pedagogy are employed for this reconsideration, stressing the operation of historical, social, ideological, political, institutional and cultural forces in the production of pedagogical practices. The effects of those forces on the production of pedagogical practices are exemplified with empirical data obtained from one classroom teachers' instructional practices in the context of mathematics teaching. The paper discusses how these dynamic forces shape the conditions under which pedagogical practices of teaching mathematics come into life. (Contains 2 footnotes.)
