My research interests focus on the intersection of intervention and implementation by developing and exploring the effectiveness of school-based academic interventions, the factors that contribute to student responsiveness of those interventions, and strategies to support intervention implementation.
Promoting youth academic success in schools
Curriculum-based assessment and data-based decision making
Math Anxiety Interventions and Contributing Factors: A series of projects are underway focusing on the impact of therapeutic and skill building interventions on math anxiety as well as the mechanisms in the instructional environment that contribute to or mitigate math anxiety.
Data-based Decision Making: In collaboration with Gena Nelson, we are working on a series of systematic and quantitative reviews of the literature on curriculum-based measurement in math.
Accelerating Math Performance with Practice Strategies (AMPPS): This project, conducted in collaboration with John Begeny at North Carolina State University, involves the development and evaluation of a resource-friendly mathematics intervention program focusing on whole number knowledge that aligns with current empirical evidence and educational policy.
The Science of Math: An advocate and founding member; projects include dissemination of the integration of the science of learning and the science of math to impact policy and practices in K-12 math education.
