The quantitative methods used included tracing trends in hierarchically-ordered categorical data, and multilevel analyses of student scores to identify significant predictors of students? progress. Qualitative methods used included interviews with selected students in schools identified from the multilevel modeling as those in which students performed significantly better than would be predicted. By reference to these analyses as applied to one geometrical item, the paper points to how the mixing of methods shed light on trends in patterns of student response as well as on unexpected results, and led to reflexive testing of some initial assumptions about the development of mathematical reasoning. Hoyles made major input to coordinate and draw out the main points from the different methods of analysis.
