Probing teachers' pedagogical content knowledge in statistics: 'how will Tom get to school tomorrow?'

This paper provides an analysis of interview responses from 40 teachers to a student survey question based on a pictograph. Responses comprise the first segment of 30-40 minute interviews exploring teachers’ pedagogical content knowledge (PCK) in statistics at the middle school level. The responses are analysed against a back-drop of previous research on how teachers integrate their understanding to plan for appropriate learning outcomes. Four components of PCK are identified and a wide range of capability observed in the group of teachers interviewed.
