Subclaims¶
Reading the evidence codes
q is the design tier, i the impact, n the sample, and the kind with its r
the rigour judged within that kind: what each code means.
This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.
q3 i? The federal evaluation of early math curricula is described as the largest study of its kind using an experimental design, with 110 schools in total and this report covering the first cohort of 39 schools from the 2006-2007 school year. → Agodini 2009

Descriptive statement about the study's scale and design: a large-scale federal experimental study of four early math programs, with "a total of 110 schools" and this report covering the first cohort of 39 schools beginning in 2006-2007.
"The study, the largest of its kind ever to use an experimental design to study a variety of math curricula, includes a total of 110 schools. This report is based on the first cohort of 39 schools that began study participation during the 2006-2007 school year."
Discussion¶
Related Claims¶
- First-grade math achievement is significantly higher under Math Expressions and Saxon Math than under Investigations in Number, Data, and Space and Scott Foresman-Addison Wesley Mathematics — a narrower finding that bears on this claim
- The better-performing early math curricula raised achievement for several student subgroups, including students in low-scoring and high-poverty schools — a narrower finding that bears on this claim
- A large-scale rigorous study examined how four math curricula affect achievement across two years, first through second grades — a broader claim this one bears on
- A large-scale experimental study compared the effects of the four mathematics curricula on student achievement — a broader claim this one bears on
- After two years of implementation, three of four elementary math curricula outperformed the fourth on student achievement in grades 1–2 — related
- The early elementary math curriculum used by schools mattered for student achievement in first and second grade — related
- Four elementary math curricula were evaluated using an experimental design — a broader claim this one bears on
- The study examines whether some early elementary school math curricula are more effective than others at improving math achievement in schools serving a high percentage of disadvantaged students. — a narrower finding that bears on this claim
- Math Expressions and Saxon Math raise first-grade math percentile rank 9 to 12 points more than Investigations and SFAW — a narrower finding that bears on this claim
- Many U.S. students enter elementary school with poor math skills — related
