"Approaches to Qualitative Research in Mathematics Education: Examples of Methodology and Methods is a clever gift for the skeptics who believe that pursuing truth is only possible through traditional empirical research. ... The work of the contributors inspires researchers in the field of mathematics education to replicate the studies and, more importantly, creates opportunities to further reflect on the ways theories inform qualitative research designs and methods."
