Subclaims¶
Reading the evidence codes
q is the design tier, i the impact, n the sample, and the kind with its r
the rigour judged within that kind: what each code means.
This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.
q3 i3 Handwriting legibility correlates significantly with fine motor precision (r=0.78). → Seo S-M 2018
q3 i3 Handwriting legibility correlates significantly with manual dexterity (r=0.49). → Seo S-M 2018 (2)
q3 i3 Handwriting legibility shows a statistically significant inverse correlation with Functional Dexterity Test performance time (r=−0.68). → Seo S-M 2018 (3)

q3 · i3 · associational · r1
Pearson product-moment correlation analysis in 52 preschool children (mean age 69.19 ± 3.71 months) between Korean Alphabet Writing Assessment scores and BOT-2 fine motor precision. The study reports a "statistically significant correlation with fine motor precision (r=0.78)".
"handwriting legibility had a statistically significant correlation with fine motor precision (r=0.78) and a high correlation with manual dexterity (r=0.49)"

q3 · i3 · associational · r2
Same Pearson correlation analysis of 52 preschool children, for the BOT-2 manual dexterity sub-item against handwriting legibility, reporting "a high correlation with manual dexterity (r=0.49)".
"handwriting legibility had a statistically significant correlation with fine motor precision (r=0.78) and a high correlation with manual dexterity (r=0.49)"

q3 · i3 · associational · r2
Pearson correlation in the same 52-child sample between handwriting legibility and Functional Dexterity Test time (mean 32.98 ± 5.19 sec), showing "a statistically significant inverse correlation" with r=−0.68; faster in-hand manipulation related to better legibility.
"It also showed a statistically significant inverse correlation with the performance time of the Functional Dexterity Test (r=−0.68)"
Discussion¶
Learner Variables¶
- Writing Skills — outcome: instruction changes it
Related Claims¶
- In stepwise multiple regression, fine motor precision accounts for about sixty percent and Functional Dexterity Test time about four percent of handwriting legibility in preschool children — possibly the same claim (merge candidate)
- Explicit Handwriting Instruction Improves Legibility — related
- Only in the 5th-grade group were moderate positive correlations found, between visual-motor integration and motor coordination (r = 0.748) and between visual perception and dysgraphia classification (r = 0.643) — related
- Automaticity of handwriting predicts orthographic skills even when visual-motor integration is included in the model — related
- Fine motor skills show a significant moderate overall correlation (r = .329) with academic-cognitive skills in children and adolescents — related
- Children's baseline motor skills do not correlate with reading-related outcomes or with their use of movement when naming letter-sounds — related
