q4 i2 Grade level moderates the mathematics–writing relation: primary grades r = 0.52 versus adult learners r = 0.30, a statistically significant difference. → Young-Suk Grace Kim 2024

q4 · i2 · quant-synthesis · r2

Meta-analytic moderation analysis by grade level (pre-K–2, 3–5, 6–12, college and beyond) across the 211 included studies. The adult correlation of r = 0.30 was significantly weaker than primary grades (r = 0.52) and upper elementary grades (r = 0.42).

"the correlation was 0.30 (SE = 0.05, p < 0.001) for adult learners in college and beyond, which was statistically significantly weaker than the correlation for children in primary grades (r = 0.52, SE = 0.03, p < 0.001)"

Discussion¶

Related Claims¶

• Mathematics and writing skills are moderately correlated overall (r = 0.48) across 211 studies — related
• In primary grades, lower order writing and lower order mathematics skills show the strongest relation (r = 0.59); in adulthood the higher order pair is weak (r = 0.26) — related
• Standardized, normed writing assessments show a stronger mathematics–writing correlation (r = 0.50) than non-standardized writing assessments (r = 0.31) — related
• Mathematics and writing subskill category (lower vs. higher order) does not significantly moderate the mathematics–writing relation — related
