What is Purposeful Sample

Inequality of gender representation in science, technology, engineering, and mathematics (STEM) careers continues, despite the narrowing of the gender achievement gap. This chapter showcases original qualitative research that provides clearer insights into origins and effects of math anxiety as the reason females are less likely to choose (STEM) majors and related careers. The role of instruction methodology of the academic organization in perpetuating marginalization practices limits women's STEM achievement. The stage environment fit (SEF) theoretical model probes the relationship of the policies and procedures of the academic organization to the likelihood of female adult-student success in higher education. The American Statistical Association's (ASA) funding of the Guidelines for Assessment and Instruction in Statistics Education Report (GAISE) mandates reforms for mathematics instruction among the information about new research opportunities and the current state of STEM education in the United States.
