Subclaims¶

q4 i3 Within primary grades, the lower order writing–lower order mathematics pair shows the strongest relation (r = 0.59), with higher order pairs slightly weaker. → Young-Suk Grace Kim 2024 q4 i2 For university and beyond, the lower order pair correlates 0.37 while the higher order writing–higher order mathematics pair correlates 0.26. → Young-Suk Grace Kim 2024 (2)

Young-Suk Grace Kim, Dandan Yang, Jinkyung Hwang. (2024). Are Mathematics and Writing Skills Related? Evidence from Meta-Analysis. Educational Psychology Review. https://doi.org/10.1007/s10648-024-09960-4

q4 · i3 · quant-synthesis · r2

Meta-analytic disaggregation of subskill pairs by grade level (Table 2). In primary grades the low-writing/low-math pair showed the strongest relation (r = 0.59), with the higher order pairs "slightly weaker with similar magnitudes" (r = 0.47; r = 0.48).

"within primary grades, lower order writing and mathematics skills exhibited the strongest relation (r = 0.59, SE = 0.04, p < 0.001), whereas the relations between lower order writing and higher order mathematics (r = 0.47, SE = 0.06, p < 0.001) and between higher order writing and higher order mathematics (r = 0.48, SE= 0.07, p = 0.002) were slightly weaker with similar magnitudes."

q4 · i2 · quant-synthesis · r2

Meta-analytic subskill-pair analysis for university and beyond (Table 2). The higher order pair's correlation of r = 0.26 was weaker than the lower order pair's r = 0.37, suggesting shared variance between higher order skills diverges in adulthood.

"In addition, for those in university and beyond, the correlation between lower order writing and lower order mathematics skills was 0.37 (SE = 0.07, p = 0.004) whereas it was 0.26 (SE = 0.09, p = 0.03) between higher order writing and mathematics skills."

Discussion¶

Learner Variables¶

• Writing Skills — predictor: learners who differ on it differ in outcomes

Related Claims¶

• The mathematics–writing correlation is stronger in primary grades (r = 0.52) than in university and beyond (r = 0.30) — related
• Mathematics and writing subskill category (lower vs. higher order) does not significantly moderate the mathematics–writing relation — related
• Mathematics and writing skills are moderately correlated overall (r = 0.48) across 211 studies — a broader claim this one bears on
