The Resilience of Overgeneralization of Knowledge about Data Representations

چکیده
Data analysis has become a topic of increasing emphasis within middle school mathematics in the last few years, especially in the recent recommendations by the National Council of Teachers of Mathematics (NCTM 2000). In order to better inform efforts to expand data analysis’s role in middle school curricula, we have begun the development of a cognitive model of student thinking in this domain. Proper representation of data is an essential part of the process of data analysis (Larkin and Simon 1987) -therefore, we have focused on modeling how students learn to generate and interpret some of the important and widely-used representations of data, such as histograms and scatterplots.
