Louise Spence Griffeth Fellowship for Excellence

Sarah R. Powell is an Associate Professor in the Department of Special Education. Powell is currently Principal Investigator (PI) of a four-year Institute of Education Sciences efficacy grant related to word problems and equation solving for third-grade students with mathematics difficulties. Powell is also PI of a five-year early numeracy and literacy read-alouds project funded by the T.L.L. Temple Foundation, PI of a one-year Texas Education Agency network about tiered intervention practices, co-PI of a National Science Foundation grant aimed at developing a science intervention for second-grade students with learning difficulties, and co-PI of an Office of Special Education Programs model demonstration grant for middle school algebra readiness. Powell was awarded the Presidential Early Career Award for Scientists and Engineers (PECASE) in 2019. Powell's research interests include developing and testing interventions for students with mathematics difficulties, with a special emphasis on peer tutoring, word-problem solving, mathematics writing, and the symbols and vocabulary within mathematics.

**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.
