There are three articles in this month's "Research Commentary" section. Analyses of disparities in students' mathematics experiences and outcomes are an essential part of efforts to promote equity. Scholars concerned about equity should not write off such analyses as mere "gap gazing." Research on gaps between underserved groups and their more advantaged peers are important for shaping public opinion and informing education policy. Analyses of gaps also inform mathematics education research and practice, illuminating which groups and curricular areas are most in need of intervention and additional study.
