Excited to share that I'll be giving a keynote at IMBES in September. The talk asks a simple question: Are we measuring children's cognition, or the interaction between cognition and context? Looking forward to sharing (and hopefully generating discussion) in San Diego.

New 📄 on sense of belonging for Black & Latine adolescents in math! Led by @drbrookeedu.bsky.social, w/Dr. Nicolai & Dr. Chen, we examine belonging as dynamic, contextual, & shaped by racialized & cultural experiences, w/implications for math learning environments tinyurl.com/HarrisThomas...

Examining Black and Latine Students’ Sense of Belonging within the Mathematics Classroom: A Narrative Review - Educational Psychology Review
Academic environments that support a sense of belonging, or students’ feelings of being included, valued, accepted, and supported, are positively associated with students’ engagement, persistence, and academic achievement. This is particularly true for Black and Latine adolescent students in U.S. mathematics classrooms. Research has also shown that students’ sense of belonging is a situated, malleable construct that can fluctuate throughout the school day. This narrative review examines how the dynamic nature of belonging interacts with the complex consideration of adolescent Black and Latine students’ ethnicity, race, and culture within the context of mathematics. We advance three considerations for researchers when investigating and supporting the belonging experiences of Black and Latine students within mathematics: Contextual Factors that Shape Sense of Belonging to Mathematics, Positionality and Framing of Investigations of Belonging, and Recognizing the Whole Student. By critically examining the educational contexts in which Black and Latine adolescent students engage with mathematics, alongside the prevailing frameworks and assumptions adopted in research studies, researchers are more likely to adopt a holistic perspective toward these students. Consequently, this approach fosters the production of research findings that affirm and enhance, rather than undermine, Black and Latine students’ sense of belonging within mathematical learning environments. Recommendations for research and practice are also shared.
