The Tattslotto question: exploring PCK in the senior secondary mathematics classroom

Pedagogical Content Knowledge (PCK) is a powerful construct for examining the complexity of teacher knowledge. Together with teachers’ moment-by-moment choices of action, it provides insight into teachers’ knowledge and its influence on student learning. This paper investigates the PCK experienced by a senior secondary mathematics class during a lesson on probability. Data were gathered through observation, and student and teacher interviews. Multiple aspects of PCK were evident and were used in complex and dynamic ways.
