Sarah R. Powell is an Assistant Professor in the Department of Special Education. After teaching kindergarten, Sarah worked at Vanderbilt University as a project coordinator of grants related to word-problem solving and computation for elementary students. Sarah’s dissertation focused on providing instruction about the equal sign (=) to students with mathematics difficulty. Her dissertation won awards from the Division for Learning Disabilities of the Council for Exceptional Children and the Council for Learning Disabilities. Sarah also won the Early Career Publication Award from the Division for Research of the Council for Exceptional Children. Sarah’s research interests include developing and testing interventions for students with mathematics difficulties. She is especially interested in peer tutoring, word-problem solving, and the role of symbols for understanding mathematics. During two years as an Assistant Professor at the University of Virginia, Sarah designed and implemented randomized-control trials related to nonsymbolic understanding of mathematics, manipulative use, and explicit mathematics vocabulary instruction for students with mathematics difficulties.
