Developing connections between word problems and mathematical equations to promote word-problem performance among students with mathematics difficulty.
This is an Institute of Education Sciences Goal 3 efficacy trial in which we determining the role of algebraic reasoning within word-problem solving for third-grade students with learning difficulties.

Understanding the influence of math symbols and vocabulary on math performance
With this National Academy of Education/Spencer Postdoctoral Fellowship, I am exploring the mathematics vocabulary and symbol knowledge of students in the elementary and middle school grades.

Investigating the effects of algebra and rational numbers performance on post-secondary preparation, access, and persistence for students with and without mathematics difficulty
With this three-year Greater Texas Foundation Faculty Fellowship, I am investigating the connections between college algebra and rational number understanding.

Interactive read-alouds for prekindergarten and kindergarten to improve literacy and numeracy skills
The primary purpose of this 5-year project is to develop interactive read-aloud resources for educators and caregivers that are empirically derived and improve valued outcomes related to mathematics, language, and reading. We work with educators in preschool and early-elementary settings and the caregivers of the children who receive educational services in such settings. We design interactive read-aloud materials focused on helping educators and caregivers capitalize on the rich array of early-numeracy and literacy trade books available in libraries, classroom collections, or in the home.

Project STAIR: Supporting teaching of algebra: Individual readiness
This is an Office of Special Education Programs (OSEP) model demonstration grant funded from 2018-2019. In collaboration with the University of Missouri and Southern Methodist University, we will work with middle school teachers of students with learning difficulties to increase algebra readiness.
