Inequity is a pressing concern in the mathematics education community. Recent research shows how inequity in everyday classroom interaction can shape student participation in subtle ways. This paper focuses on a tool, EQUIP, which uses a quantitative approach to illuminate aspects of such inequities. EQUIP cross-tabulates relatively low-inference…

Research has revealed that students in online classes may have higher rates of attrition than those in traditional face-to-face classes. Effective teaching and learning in an online environment requires different pedagogical skills than those used in traditional face-to-face classes. Online courses must focus on the quality of interaction. As an…

This dissertation examines the patterns and types of mistakes students make on a large-scale mathematics assessment, and puts these patterns into perspective based on the textbook used and the specific content covered in a student's classroom. In order to investigate the nature of these patterns, I employ a method of analysis originally designed…

Methods exist for testing the homogeneity of group regression for the case in which there is only one predictor. Studies which have investigated aptitude-treatment interactions have adopted the homogeneity of regressions test as standard methodology for assessing the difference in regression slopes across treatments. Additional statistical…
