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 i? LA-Severe Fact Retrieval children show retrieval deficits with intact procedural competence, and their number sets and number line deficits are modest and improve from second to fourth grade. → Geary 2012

q3 · i? · associational · r2
Multilevel analyses of a procedural competence variable, d-prime from the Number Sets Test, and number line absolute error across grades 2-4. The study's summary states retrieval deficits occur "with intact addition procedural competencies" and that unlike retrieval errors, number competencies improve across grades.
"First, the addition fact retrieval deficits of the children in the LA-Severe Fact Retrieval group are found with intact addition procedural competencies."
Discussion¶
Learner Variables¶
- Arithmetic Fact Retrieval — outcome: instruction changes it
Related Claims¶
- After controlling for domain-general abilities and reading, MLD children show deficits on all mathematical cognition tasks while LA-Severe children show a specific counting-string intrusion deficit — related
- Counting-string intrusion errors are as common in LA-Severe Fact Retrieval children as in children with MLD, but decline across grades only for the MLD group — related
- LA-Severe Fact Retrieval children commit retrieval errors on forced retrieval at rates equal to children with MLD, with no across-grade improvement — related
- Children with LA show a less severe impairment pattern than children with MLD, differing only on symbolic approximate addition — related
- Low- and high-performing students make different types of errors and therefore need different kinds of support — related
- No profile distinguishes more severe, persistent, or specific MLD from less severe MLD on cognitive skills — related
