Moody Department of Mathematics, Western Kentucky University, Bowling Green, United States Liesel Gardner EDUCATION20142810 10.12691/education-2-8-10 2014 07 17 2014 07 25 2014 07 30 As part of the requirements for teaching certification, secondary mathematics pre-service teachers enrolled in a teacher preparation program at an American university in the southeastern United States participate in a capstone mathematics course that focuses on conducting research on some topic of interest. This paper is an investigation of one pre-service teacher's challenge to complete this requirement by designing and implementing a research project that required statistical examination and analysis. Findings show that although the pre-service teacher was mathematically able and possessed a depth and breadth of knowledge in mathematics, she struggled with using appropriate statistical methods to carry out the research project. These findings suggest that mathematics teacher education programs need to be intentional about creating opportunities for pre-service teachers to engage in statistical inquiry.
