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.
q2 i? After two years of implementation in grades 1-2, three elementary math curricula outperformed a fourth curriculum on student achievement. → Agodini 2013
q2 i? In a large-scale study of four elementary math curricula followed across first and second grades, three curricula outperformed the fourth after two years. → Agodini 2013

q2 · i? · causal · r?
The brief's headline finding, stated in its title, is that after two years three of the four studied elementary math curricula "Outperform a Fourth". The available text states the comparison only at summary level; no effect sizes or test statistics are printed in the supplied text.

Discussion¶
Related Claims¶
- 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
- 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 study is the largest experimental-design study of multiple math curricula, covering 110 schools with this report based on the first cohort of 39 schools — related
- 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
- The early elementary math curriculum used by schools mattered for student achievement in first and second grade — a broader claim this one bears on
- Four elementary math curricula were evaluated using an experimental design — a broader claim this one bears on
- Math Expressions and Saxon Math raise first-grade math percentile rank 9 to 12 points more than Investigations and SFAW — related
- The evaluation uses a school-level random assignment design to estimate the relative effects of four early elementary math curricula — related
- A large-scale experimental study compared the effects of the four mathematics curricula on student achievement — a broader claim this one bears on
- Many U.S. students enter elementary school with poor math skills — related
- The curriculum evaluation was the second report from a multi-year (2005-2013) IES-funded study of mathematics curricula — related
