Math Expressions, Saxon aid learning

In a large-scale federal study of four early math curricula, Math Expressions and Saxon Math significantly outperformed two other widely used programs, reports Mathematica.

Among first-graders, math achievement was significantly higher in schools assigned to Math Expressions than in schools assigned to Investigations in Number, Data, and Space (Investigations) and Scott Foresman-Addison Wesley Mathematics (SFAW). The effect is strong enough that an average-performing student’s percentile rank would improve by 5 points.

Among second-grade students, math achievement was significantly higher in schools assigned to Math Expressions and Saxon Math than in schools assigned to SFAW. The effect is equivalent to improving an average-performing student’s percentile rank by 5 to 7 points.

Math Expressions and Saxon Math improved results for students in schools with low math scores and students in high-poverty schools.
