Kiyomi Sánchez-Suzuki Colegrove, an assistant professor in the Department of Curriculum and Instruction at Texas State University, has co-authored research challenging "Word Gap" theory in education.

The research article, "How the Word Gap Argument Negatively Impacts Young Children of Latinx Immigrants’ Conceptualizations of Learning," appears in the fall 2017 edition of the Harvard Education Review and was featured in the October 22 edition of the Washington Post, in “Why a key research finding is ruining education in Texas.”

Colegrove co-authored the article with University of Texas at Austin professor Jennifer Keys Adair and UT doctoral student Molly E. McManus. The article may be found at

The research details how widespread acceptance of the “word gap” theory perpetuates discrimination against children of Latino immigrants, despite educators’ best intentions. The word gap theory, based on a 1995 study by University of Kansas psychologists Betty Hart and Todd R. Risley, states that impoverished children hear fewer words in their first four years than affluent students. Because of this, Colegrove argues children of Latino immigrants are exposed to less dynamic forms of learning out of concern they aren't as prepared as their white, native-born peers.

Colegrove specializes in bilingual and bicultural education at Texas State. In addition to the Harvard Education Review, she has published in Contemporary Issues in Early Childhood Education, Bilingual Research Journal, Teachers College Record and Asia-Pacific Journal of Research in Early Childhood Education. Her research focuses on the curricular and pedagogical preferences of Latino immigrant parents and the relationship between home and school, particularly in the early grades.
