This experimental randomized control trial (RCT) was sponsored by the U.S. Department of Education Institute of Education Sciences (IES), and was conducted by Mathematica Policy Research and a main subcontractor, SRI International (SRI). This Grade 1 and 2 RCT included 110 schools and random assignment of one of four math curricula (Math Expressions, Saxon Math™, Scott Foresman-Addison Wesley (SFAW), & Investigations in Numbers, Data, and Space). HLM results indicated that students participating in Math Expressions classrooms had significantly greater math achievement as measured by the ECLS-K math assessment. In Grade 1 classrooms, average math achievement of Math Expressions students was 0.11 standard deviations higher than that of both Investigations and SFAW students; in Grade 2 classrooms, average math achievement of Math Expressions and Saxon students was 0.12 and 0.17 standard deviations higher than that of SFAW students, respectively.
