In the American school system, math and science are considered essential building blocks of a good education. But for many students, those building blocks can topple over somewhere along the way. We spoke to Professor Lara Perez-Felkner, who laid out invisible barriers faced by racially minoritized and economically disadvantaged students pursuing STEM (Science, Technology, Engineering, Mathematics). Perez-Felkner discussed ways that school administrators, policymakers, and families can come together to remove these barriers and increase opportunity –  all the way from kindergarten classrooms to college laboratories.  For more on this topic: Check out Lara Perez-Felkner’s SSN brief: Transforming Opportunity to Support STEM Success for All.  Read her paper, co-authored by Samantha Nix: Difficulty Orientations, Gender, and Race/Ethnicity: An Intersectional Analysis of Pathways to STEM Degrees
