Alternative Interpretation of the Dataset on K-12 Calculator Usage and College Grades as Analysed by Wilson and Naiman (2003, 2004)

The short communication on ‘K-12 Calculator Usage and College Grades’ by Wilson and Naiman (2004) reports that ‘there is a (negative) connection between’ college mathematics grades at Johns Hopkins University and heavy calculator usage in K-12' (p. 121). This response argues that such a conclusion risks oversimplifying the situation examined; evidence from an earlier version of the report suggests that the multi-course dataset is non-homogeneous, and that a correspondingly less generalised conclusion would be more appropriate. This response also notes some other limitations of the mechanism of comparison employed.
