Mathematical problems in children with developmental coordination disorder

Area of Science:

• Neuroscience
• Developmental Psychology
• Educational Psychology

Background:

• Developmental Coordination Disorder (DCD) is a heterogeneous condition often co-occurring with learning disabilities.
• Mathematical challenges in children with DCD are under-researched.
• Understanding these challenges is crucial for targeted interventions.

Purpose of the Study:

• To investigate mathematical problems in children with varying degrees of motor impairments associated with DCD.
• To determine if mathematical skill development in DCD is delayed or deficient.
• To compare mathematical performance between children with mild and severe DCD.

Main Methods:

• Comparison of mathematical skills (number fact retrieval, procedural calculation) between children with DCD and age-matched controls.
• Assessment of children with DCD across different severity levels (mild vs. severe).

Main Results:

• Children with DCD performed significantly worse than controls in number fact retrieval and procedural calculation.
• Significant differences in mathematical performance were observed between children with mild and severe DCD.
• A developmental delay of 1 year for number fact retrieval in mild DCD and 2 years in severe DCD was identified.
• No evidence of a specific mathematical deficit was found, suggesting delays rather than fundamental deficiencies.

Conclusions:

• Mathematical skills, including number fact retrieval and procedural calculation, are significantly impacted in children with DCD.
• The severity of motor problems in DCD correlates with the extent of mathematical developmental delay.
• Findings suggest a developmental delay rather than a deficit, with important implications for diagnosis and educational support.
