ab: Summary: Research in mathematics education stresses the importance of
content knowledge in solving authentic tasks in statistics and in
risk-based decision making. Existing research supports the claim that
students rely on content knowledge and context expertise to make sense
of data. In this article, however, I present evidence that the
relationship between content knowledge and statistical inference is
bidirectional: it is true that students rely on content knowledge to
make sense of data, but the converse also holds true. This claim is
illustrated and supported by a case study of Grade 11 students (19
girls and 4 boys) as they determine the risk of nuclear power plant
accidents. I present a conceptual model of society that emerges from
the case study as students struggle to operationalize the concept of
impact of nuclear power plant accidents. Findings suggest that the
relationship between content knowledge and mathematical knowledge is
complex. Finally, this research shows how authentic tasks in the
mathematics classroom can be used to foster students’ sense of
citizenship.
