Biased Sampling and PCK: The Case of the Marijuana Problem
Watson, Jane M.; Nathan, Erica L.
Mathematics Education Research Group of Australasia, Paper presented at the Annual Meeting of the Mathematics Education Research Group of Australasia (33rd, Freemantle, Western Australia, Jul 3-7, 2010)
As part of an interview protocol investigating teachers' pedagogical content knowledge (PCK) in statistics, 40 teachers were presented with a newspaper article reporting a phone-in survey about the legalisation of marijuana. The article and a question about the reliability of the sample had earlier been used in student surveys, and three student answers to the question were also presented to the teachers. Teachers' PCK was assessed based on responses to questions about the big ideas in the task, potential student appropriate and inappropriate answers, and how teachers would intervene in relation to the three student answers. The wide range of responses provided evidence for the potential of the task in a cross-curricular secondary classroom. (Contains 2 tables.)
