About Us
HOLA!!! We are the HOLA STEM Lab, and we aim to recognize and promote positive experiences, practices, and opportunities for Latine families to advance the development of their children’s early STEM (science, technology, engineering, and math) skills.
Latine families bring immense linguistic and cultural assets to schools and communities. This group is the fastest-growing population in the US (one in four children in the U.S. are Latine).
We strive to value and leverage Latine families’ knowledge, experiences, and practices in STEM with an asset-oriented vision. Latine families, however, are not a monolithic group, and the ways in which caregivers engage with their children in STEM may vary due to essential factors, such as, for example, who is in the home and caregivers' generational status in the U.S. That is why we also examine within-group variation in Latine families' engagement.
Meet our Team
I am an Assistant Professor in the Human Development program at the University of Maryland. I was born and raised in Argentina. I came to the US to pursue my master’s degree in Comparative and International Education at New York University. I did my Ph.D. in Educational Psychology and Research Methodology at Purdue University.
My overarching research program explores learning contexts that shape how young children develop and learn, with a particular focus on dual language learners (DLLs) from immigrant Latine communities. Latine families bring immense linguistic and cultural assets to schools and communities, yet Latine children are considered among the most vulnerable of young learners. Disparities in learning outcomes, however, rest within structural factors such as cultural and linguistic biases in our knowledge base and the reliance on measures that are not culturally or linguistically sensitive but commonly used to make instructional and policy decisions.
My research program addresses these main issues through two main strands: (a) culturally sensitive measures and (b) contextual factors shaping early learning, with a specific interest in early mathematics skills.
Current Graduate Students
Ninie Asad
Ninie is a first-year Ph.D. student in the Department of Human Development and Quantitative Methodology. She is interested in how Latine families support their children’s learning in ways that don’t always fit traditional ideas of academic help. Her goal is to create research and resources that are accessible, inclusive, and useful for families and schools, especially in supporting dual-language learners and diverse learning experiences. Ninie received her dual Bachelor of Science degrees in Human Development and Family Sciences and Psychology from Virginia Tech and in her post-bacc years worked at the Early Childhood Interaction Lab at UMD.
Current Graduate Research Assistants
Maylee Montagut Ascanio
Maylee is a third-year Ph.D. student in the Department of Human Development and Quantitative Methodology working both at The ECI Lab and HOLA STEM Lab. She is interested in analyzing the role of working memory and gesture-use in latine parents and children's communication, and how it influences early math development. She earned her B.A. in Psychology at Universidad de Los Andes in Bogotá, Colombia. For her post-bacc years, Maylee worked as a researcher in the education field, developing and applying tools to measure the quality of early childhood classrooms and caregiver-child interactions in public daycares and schools in Colombia.

Projects
Mathematics in the home of Latine families
In this project, we aim to validate a recently developed measure of the home mathematics environment (HME) for Latine families (HME-L).
With this measure, we aim to shift attention from what Latine families do not know or do to valuing and leveraging their everyday practices and experiences.
Latine STEM home-practices and digital support
In this project, we aim to design family STEM resources (i.e., an app) using a bottom-up approach. We are conducting focus groups with Latine families to learn about their everyday practices and the use of technology.
This work will promote meaningful STEM content in activities and interactions already taking place in Latine families' homes.
Dual language learners' school readiness skills
In this project, we aim to examine how Latine dual language learners (DLLs) perform in different school readiness domains (e.g., science, math) based on the English language skill test (preLAS). We are using two nationally representative datasets.
This work raises concerns about the validity of English-based assessments for Latine DLLs. Being DLL is a cognitive benefit that should be celebrated and encouraged; however, assessments in one language do not accurately capture DLLs’ academic abilities.
