Subclaims¶

q2 i? Grades 2, 3, and 5 that fully implemented ST Math had significantly higher scale scores and larger advanced and proficient-or-advanced proportions than matched comparison grades; no statistically significant differences were found on any outcome for grade 4. → Staci Wendt 2014

q2 · i? · causal · r2

Grade-level ANCOVA analyses (Exhibit 5) of fully implementing grades matched to comparisons; the article reports grades 2, 3, and 5 significant after BH correction and grade 4 not significant, with no standardized effect size printed in the prose for this finding.

"The analyses of grades that fully implemented ST Math in 2010/11 revealed statistically significant differences for grades 2, 3, and 5, but not for grade 4 (Exhibit 5). Specifically, after accounting for several school-level factors and second-grade math proficiency rates from the year before ST Math was provided, second grades that fully implemented ST Math had students with CST mathematics scale scores that were, on average, 15.48 points higher than the CST scores of students in matched second grades that were not provided with the program."

Related Claims¶

• Schools implementing ST Math with fidelity in at least one grade level showed larger math advantages (ES 0.31-0.35) than matched comparison clusters — related
• Among grades provided with ST Math, only grade 2 showed statistically significant CST advantages; grades 3, 4, and 5 did not — reports the opposite
• Grades provided with ST Math have significantly larger proportions of students advanced, or proficient or advanced, on the mathematics CST than comparison grades — related
• Grade-level clusters provided with ST Math scored higher on state math proficiency rates and scale scores than matched comparison clusters across grades 3-5 — related
• The ST Math evaluation's quasi-experimental design cannot rule out selection bias because treatment grades volunteered to participate — related
• Implementation fidelity was defined as at least 85 percent student enrollment and at least 50 percent grade-level content coverage in ST Math — related
