This Presentation discusses research and practices on supporting the continued interest, retention, and academic success of underrepresented, marginalized, and racialized students in postsecondary STEM education. Coming from a Critical-Identity-Cultural-Ecology perspective, we will discuss the various barriers that underrepresented, marginalized, and racialized students face in postsecondary STEM education, as found in the research literature and institutional data, and go over paradigms and pedagogical practices designed to integrate students’ identities and experiences within their STEM learning.
