The College of Education at The University of Texas at El Paso (UTEP), a public Hispanic Serving Institution (HSI) in El Paso, Texas seeks $600,000 over four years to support an investigation entitled Associations Between Mexican-American Early Childhood Education (ECE) Teacher Stress and Mexican-American Child Executive Function and Vocabulary, which has been developed for consideration for the Institute of Education Sciences' Research Training Programs in the Education Sciences: Early Career Development and Mentoring Program for Faculty at Minority-Serving (MSI). This project is led by Dr. Cynthia A. Wiltshire, a third-year, tenure-track Assistant Professor of Early Childhood Education in the College of Education at UTEP. The primary goals of the investigation are to understand the experiences of stress, both physiological and psychological, with which Mexican-American ECE teachers contend, and examine the relationship between these experiences and student outcomes in executive function and vocabulary. To do so, the proposed study has four research aims: Aim 1) characterize psychological and physiological Mexican-American ECE teacher stress, Aim 2) examine associations between high and low physiological and psychological Mexican-American ECE teacher stress and sociodemographic factors, Aim 3) record the lived experiences of Mexican-American ECE teachers, and Aim 4) examine associations between Mexican-American ECE teacher stress and Mexican-American child outcomes in executive function and vocabulary skills. This project should be considered under the Teaching, Teachers, and the Education Workforce and the Early Learning Programs and Policies research topics and the Exploration project type. The target populations include 1) Mexican-American ECE workforce members (e.g., district teachers, childcare workers), and 2) Mexican-American preschoolers (e.g., PreKindergarten, Head Start) in the El Paso, Texas community.
