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.

q2 i? Approximately half of children with DCD experience difficulty learning to write. → Biotteau M 2019 q2 i? Diagnosis of dysgraphia is essential because handwriting difficulties cannot be resolved without intervention and intervention seems effective for dysgraphia rehabilitation. → Biotteau M 2019 (2)

q2 · i? · review · r2

The review states, citing Hamstra-Bletz and Blöte, that "about half of all children with DCD experience difficulty learning to write", framing handwriting as a social prerequisite for communication whose failure severely affects academic success.

"Beyond the heterogeneous motor deficits, about half of all children with DCD experience difficulty learning to write.36 Handwriting skills are a social prerequisite for communication."

Biotteau M 2019 (2)¶

q2 · i? · review · r2

The review gives two reasons dysgraphia diagnosis is essential: handwriting difficulties "cannot be resolved without intervention" and intervention seems effective for rehabilitation, citing Feder and Majnemer. No effect sizes are printed.

"Therefore, the diagnosis of dysgraphia is essential for two reasons: 1) handwriting difficulties cannot be resolved without intervention and 2) intervention seems to be effective for dysgraphia rehabilitation.37"

Discussion¶

Learner Variables¶

Writing Skills — outcome: instruction changes it

DCD prevalence estimates range from 1.8% to 6.9% with a male predominance of 2:1 to 3:1, and the disorder persists into adulthood for 30–70% of those diagnosed as children — related
Explicit Handwriting Instruction Improves Legibility — a broader claim this one bears on
Different types of handwriting interventions produce equivalent gains in handwriting legibility and fluency — related
Developmental writing disorders affect about 7–15% of school-aged children, with boys more affected than girls — related
