q3 · i? · causal · r?

Experimental evaluation of four elementary math curricula reporting a curricula comparison for first-grade math achievement. The article reports a 9 to 12 percentile-point advantage for "Math Expressions or Saxon™, instead of Investigations® or SFAW" for an average-performing first-grader; no standardized effect size is printed.
