Discussion¶

Related Claims¶

• A large-scale experimental study compared the effects of the four mathematics curricula on student achievement — a broader claim this one bears on
• 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 — 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 evaluation uses a school-level random assignment design to estimate the relative effects of four early elementary math curricula — possibly the same claim (merge candidate)
• 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
• Effects were larger in intervention schools with a higher percentage of economically disadvantaged students or a lower percentage of White students — a narrower finding that bears on this claim
• The curriculum evaluation was the second report from a multi-year (2005-2013) IES-funded study of mathematics curricula — related
• A large-scale, rigorous study compared four elementary math curricula's effects on achievement across two years, first through second grade — related
• Math Expressions and Saxon Math raise first-grade math percentile rank 9 to 12 points more than Investigations and SFAW — related
