Mariana Alvidrez serves as an assistant professor of STEM education in the School of Teacher Preparation, Administration, and Leadership in the College of Health, Education, and Social Transformation at New Mexico State University. Throughout her professional journey, she has developed her expertise by engaging in various capacities within STEM education fields on both sides of the U.S.-Mexico border community. Mariana Alvidrez’s research is centrally concerned with inclusion, exclusion, equity, belonging, and justice issues in STEM education. She is especially interested in examining Latino/a/e students’ experiences in STEM education, often shaped by systemic racism and intersecting systems of oppression. More specifically, her previous and still ongoing work has focused on how teachers of mathematics frame students’ errors and how their framings promote or hinder students’ opportunities to learn, sense of agency, and the development of identities as capable thinkers and doers in the context of mathematical classrooms. Furthermore, among her ongoing projects, she is currently investigating how Latino/a/e computer science students develop their professional skills and identities, centering them as co-researchers and co-designers.
