Dr. 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 mathematics and computer science education, which are 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. She has been exploring how these framings either support or impede students' learning opportunities, the development of their sense of agency, and the formation of their identities as capable thinkers and doers within the mathematical classroom environment. Furthermore, among her ongoing projects, she is currently investigating how Latino/a/e computer science students develop their professional skills and identities through the analysis of their mistakes.
