Dr. Barbieri is the Director of the M^3 lab: Math Methods & Motivation. Her research program focuses on understanding and implementing the types of opportunities students need to thrive in mathematics classrooms, whether that be in the form of specific types of instructional tools or in a climate that fosters positive mathematics attitudes. Though there are many factors that impact mathematics learning and development both in and outside the classroom, Dr. Barbieri’s work focuses on factors that are within control of teachers and administrators: design and effectiveness of instructional tools and approaches. More specifically, her work is centered on using principles from cognitive and learning sciences as well as motivation to improve mathematics competencies, especially for those who struggle more with mathematics. A necessary component of designing instructional tools to support mathematics learning is to understand the specific concepts, procedures, and types of knowledge that students struggle with most. Thus, some of her work focuses on examining students’ demonstrated knowledge as well as mathematical misconceptions and misunderstandings (i.e., incorrect or partial understandings of mathematical concepts). To date, her research has focused primarily on algebra and fractions, both gateway topics for success in STEM disciplines and careers. Dr. Barbieri is particularly concerned with learning opportunities in school settings that serve underrepresented racial and ethnic minority students. A second growing line of her work examines the opportunities these students are given to have positive experiences in their mathematics classrooms that may support their learning, belonging, and math identity.
