Dr. Ben Clarke is an Associate Professor in the School Psychology Program at the University of Oregon. He is interested in the development of mathematical and the role of assessment, instruction, and school systems to support that development. Across his work, there is an emphasis on understanding the variables that impact student achievement and their interaction with critical ecological and cultural factors. Dr. Clarke leverages his research interests to teach and work with school psychology and special education students to integrate an understanding of mathematics development within school based service delivery systems. He currently serves or has served as a Principal Investigator on twenty federally funded research grants (apx. 55 million in funding) in the area of mathematics instruction focused on the development and efficacy testing of intervention programs spanning the K-6thgrade spectrum in both traditional and technology based formats. In addition, Dr. Clarke’s work has focused on developing assessment materials examining early mathematics knowledge and number sense with a focus on identifying and preventing later mathematics difficulty. He has published articles and book chapters on mathematics instruction and assessment and developing multi-tiered instructional models including the IES practice guide “Assisting students struggling with mathematics: Response to Intervention for elementary and middle schools”. Dr. Clarke was a practicing school psychologist for three years where he led district efforts to implement multiple tier instructional models in reading and mathematics.
