Mathematical thinking in second-grade children with different forms of LD

Area of Science:

• Educational Psychology
• Developmental Psychology
• Cognitive Science

Background:

• Identifying distinct profiles of learning difficulties in children is crucial for targeted interventions.
• Mathematics and reading difficulties often co-occur, but their specific impact on mathematical thinking requires further investigation.

Purpose of the Study:

• To differentiate the mathematical thinking abilities of second-grade children with varying profiles of mathematics and reading achievement.
• To investigate whether children with mathematics difficulties (MD) and co-occurring reading difficulties (MD/RD) exhibit different patterns of mathematical deficits compared to children with MD only.

Main Methods:

• Classified 49 second-grade children into four groups: MD only, MD/RD, RD only, and normal achievement (NA) based on standardized test performance.
• Assessed mathematical thinking across number facts, story problems, place value, and written calculation using a series of tasks.
• Compared performance across groups using statistical analyses.

Main Results:

• Children with MD/RD performed significantly worse than NA children in most mathematical areas.
• Children with MD only showed deficits primarily in complex story problems compared to NA children.
• The MD-only group outperformed the MD/RD group in story problems and written calculation, highlighting distinct profiles.

Conclusions:

• The subgroup of children with both mathematics and reading difficulties (MD/RD) presents with pervasive mathematical thinking deficits.
• Children with mathematics difficulties only (MD only) exhibit more specific deficits, particularly in problem-solving.
• These findings underscore the importance of distinguishing between MD/RD and MD-only subgroups for effective educational support.
