"Achievement Effects of Four Early Elementary School Math Curricula: Findings for First and Second Graders," Roberto Agodini, Barbara Harris, Melissa Thomas, Robert Murphy, and Lawrence Gallagher, October 2010. This report, the second from the study, shows that the curriculum used by the study schools mattered during a first year of implementation. The four curricula examined include (1) Investigations in Number, Data, and Space (Investigations), (2) Math Expressions, (3) Saxon Math (Saxon), and (4) Scott Foresman-Addison Wesley Mathematics (SFAW). Among first-graders, math achievement was significantly higher in schools assigned to Math Expressions than in schools assigned to Investigations and SFAW. Among second-graders, achievement was significantly higher in schools assigned to Math Expressions and Saxon than in schools assigned to SFAW. Read the release. "NCEE Study Snapshot" (October 2010): This snapshot summarizes the findings presented in the second study report. Consistent with the report, the snapshot shows that first- and second-grade math achievement differed among students in schools that were randomly assigned to use one of four curricula: (1) Investigations in Number, Data, and Space; (2) Math Expressions; (3) Saxon Math (Saxon); and (4) Scott Foresman-Addison Wesley Mathematics (SFAW). Among first graders, the results favored Math Expressions over both Investigations and SFAW, but not over Saxon. Among second graders, the results favored Math Expressions and Saxon over SFAW, but not over Investigations. Future ReportsThe study released a second impact report on the relative effects of the curricula in October 2010. The report examines first-year relative curriculum effects on first- and second-grade students who participated in the study during the 2006-2007 or 2007-2008 school years. A first impact report was released in 2009 that examined the relative effects of the curricula on the first-grade students who participated in the study during the 2006-2007 school year. A third report is planned that will present results for a subset of students and teachers who used each curriculum for more than one year. The third report is expected in Summer 2012. |
