- Department-funded evaluation (findings for Teach to One: Math (TtO))
- Quasi-Experimental Design
- Meets WWC standards with reservations because it uses a cluster quasi-experimental design that provides evidence of effects on clusters by demonstrating that the analytic sample of individuals is representative of the clusters and satisfying the baseline equivalence requirement for the clusters in the analytic intervention and comparison groups.
This review may not reflect the full body of research evidence for this intervention.
Evidence Tier rating based solely on this study. This intervention may achieve a higher tier when combined with the full body of evidence.

Study Details
Setting
The study took place in schools in Elizabeth, NJ that served students in sixth, seventh, and eighth grades. In intervention schools, students from multiple classrooms gathered together in a single location to work in teacher-led, peer-to-peer, or individual sessions using a laptop to log into an online portal with a personalized set of instructional activities. Five schools implemented the intervention and 16 schools served as the comparison group.
Study sample
At baseline, intervention and comparison schools were 48% female, 9% students with limited English proficiency, 10% enrolled in special education, 77% eligible for free lunch, 10% eligible for reduced price lunch, 2% Asian, 23% Black, and 68% Hispanic, with 8% of unspecified race/ethnicity.
Intervention Group
The Teach to One: Math (TtO) intervention is designed to increase math achievement in middle school students through a personalized instructional model for middle grade mathematics that combines resources from multiple classrooms into one open space where different students learn different skills at the same time. The theoretical basis for the intervention is that a personalized math curriculum for each student, based and updated on each day’s assessment of that student’s learning, will lead to increased math learning.
Comparison Group
The comparison schools implemented their business-as-usual mathematics instruction during the three years that the treatment schools were implementing the intervention. Teachers used their typical mathematics curriculum and likely received supports as they had in the past. Students were likely exposed to instruction as they had in the past.
Support for implementation
TtO provides teachers with instructional resources to use in teacher-led modalities as part of the intervention.
An indicator of the effect of the intervention, the improvement index can be interpreted as the expected change in percentile rank for an average comparison group student if that student had received the intervention.
For more, please see the WWC Glossary entry for improvement index.
