The purpose of this project is to develop and test the effectiveness of the NumberShire Integrated Tutor System (NS1-ITS) that will be utilized to optimally scale up implementation of an evidence-based education technology tool, NumberShire 1 (NS1), in first grade classrooms.

NumberShire is a suite of internet-based gaming interventions designed to explicitly teach students in grades K-2 whole number concepts that align with the Common Core State Standards.

PreK-K is a Goal 3 Efficacy and Replication Study focused on testing the efficacy of a combined, two-year, early mathematics intervention: Pre-Kindergarten Mathematics and Early Learning in Mathematics(PreK-K) curricula.

Precision Mathematics is a 4-year Full Design and Development (DRK-12) project funded by the National Science Foundation (NSF). The aim of the project is to develop and test 1st and 2nd grade mathematics interventions for students who are at risk for early mathematics difficulties.

Students who perform poorly in mathematics early in school are at risk for continuing to struggle in mathematics throughout elementary school and beyond. Recent empirical studies of targeted interventions for students at-risk in mathematics indicate overall effectiveness at positively impacting student outcomes.

PAR (Promoting Algebra Readiness) is a Goal 2 Development and Innovation project focused on developing a print-based intervention that targets rational number concepts.

The purpose of this NCSER Systematic Replication in Special Education research project is to conduct an efficacy replication of ROOTS, a 50-lesson (Tier 2) kindergarten mathematics intervention in which key variables related to intervention delivery will be systematically varied across different school types (i.e., urban and rural) and student popu

ROOTS is a Goal 3 Efficacy and Replication study designed to test the impact of a small-group (Tier 2) kindergarten, mathematics intervention program under three different conditions that vary in instructional intensity.

Stepping up KinderTEK is a "Stepping Up" project funded as a cooperative agreement with the Office of Special Education and Rehabilitative Services (OSEP) at the Department of Education. Its purpose is to expand the current KinderTEK iPad math intervention to more effectively serve K-Gr3 students with disabilities.
