Teaching Math in Middle School: Using Mtss to Meet All Students' Needs - Softcover

Leanne Ketterlin-Geller, Ph.D., is a Professor and the Texas Instruments Chair in Education at Southern Methodist University. Her research focuses on the development and validation of formative assessment systems in mathematics that provide instructionally relevant information to support students with diverse needs. She works nationally and internationally to support achievement and engagement in mathematics and other STEM disciplines.

Sarah R. Powell, Ph.D., is an Assistant Professor in the Department of Special Education at the University of Texas at Austin. Sarah conducts research related to mathematics interventions for students with learning difficulties. Her work is currently supported by the Institute of Education Sciences, National Science Foundation, T.L.L. Temple Foundation, and office of Special Education Programs.

Lindsey Perry, Ph.D., researches on improving students' mathematics knowledge, particularly at the elementary and middle school grades, by better understanding how children reason relationally and spatially. Her work also included the development of technically adequate assessments that can be used to improve these reasoning skills.

She holds a Ph.D. in education from Southern Methodist University, an M.Ed. in Educational Leadership and Policy Studies from the University of Texas - Arlington, and a B.A. in Mathematics from the University of Texas - Austin. After teaching elementary and middle school mathematics for two Texas school districts, Linsey served as the Assistant Director of Mathematics and as a Mathematics Assessment Specialist at the Texas Education Agency. She has also developed and led professional development opportunities for teachers in the United States, Uganda, and Malawi and worked on an international mathematics assessment for students in grades 1–3.
