What Works Clearinghouse


The review below focuses on a study of Investigations in Number, Data, and Space®. The WWC has conducted a systematic review of research studies examining the effectiveness of Investigations in Number, Data, and Space®, which includes this study, the findings from which can be found in the intervention report. The study is also included in systematic reviews conducted by the WWC examining the effectiveness of Saxon Math and Scott Foresman-Addison Wesley Elementary Mathematics. The findings from those comprehensive reviews can be found in the Saxon Math intervention report and Scott Foresman-Addison Wesley Elementary Mathematics intervention report.

What is the study about?

This study examined the relative effectiveness of four widely-used early elementary school math curricula: (1) Investigations in Number, Data and Space (Investigations), (2) Math Expressions (ME), (3) Saxon Math (Saxon), and (4) Scott Foresman-Addison Wesley Mathematics (SFAW).

What did the study authors report?

First graders attending schools assigned to the ME and Saxon curricula scored significantly higher on math assessments than students attending schools assigned to the Investigations or SFAW curricula. Math achievement did not differ significantly between schools using ME and Saxon; nor were there significant differences in student math achievement between schools using Investigations and SFAW.
