Read the final report from a large-scale, rigorous study examining how four math curricula affect achievement across two years—from first through second grades. The curricula were (1) Investigations in Number, Data, and Space; (2) Math Expressions; (3) Saxon Math; and (4) Scott...

This appendix provides the details that underlie the analyses reported in the evaluation brief, “After Two Years, Three Elementary Math Curricula Outperform a Fourth.†The details are organized in six sections: Study Curricula and Design (Section A), Data Collection (Section B),...

Mathematica provided technical assistance in developing and estimating VAMs for use in Phase 1 of the pilot.

This paper explores how the design features of curriculum materials might influence potential opportunities to learn and student outcomes through a comparative, documentary analysis of four mathematics curricula commonly used in the United States.

The Bill & Melinda Gates Foundation contracted with Mathematica to conduct an implementation study of the Strategic Data Project (SDP) and Education Pioneers (EP) programs, which aim to enhance the capacity of school districts and other education agencies to collect, manage, analyze, and use...
