q3 i? On the forced addition fact retrieval task, LA-Severe Fact Retrieval children and children with MLD erred on about 4 of 5 retrieved answers and did not differ from each other. → Geary 2012

Evidence¶

Geary 2012¶

Geary, D. C., Hoard, M. K., & Bailey, D. H. (2012). Fact Retrieval Deficits in Low Achieving Children and Children with Mathematical Learning Disability. Journal of Learning Disabilities, 45(4). https://doi.org/10.1177/0022219410392046

q3 · i? · associational · r2

Longitudinal multilevel analysis (PROC MIXED) of forced retrieval task performance from second to fourth grade in 231 children classified into four groups. The study reports "about 4 out of 5 retrieved answers were errors" for both groups, with no significant group difference (t < 1).

"For the LA-Severe Fact Retrieval children and the children with MLD, about 4 out of 5 retrieved answers were errors; these groups did not differ (t < 1)."

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
• Children with LA show a less severe impairment pattern than children with MLD, differing only on symbolic approximate addition — reports the opposite
• Fact retrieval deficits in LA-Severe children occur alongside intact addition procedural competencies and modest, improving number-task performance — related
