Dimensionality of Preschoolers' Informal Mathematical Abilities

Area of Science:

• Child Development
• Educational Psychology
• Cognitive Science

Background:

• Previous research on early math skills predominantly focused on number and operations.
• Dimensions like measurement, geometry, and patterning received less attention in early childhood math development.

Purpose of the Study:

• To investigate the dimensionality of informal mathematical abilities in preschoolers.
• To determine if mathematical abilities differ between male and female preschoolers.

Main Methods:

• Categorical confirmatory factor analysis (CCFA) was employed using data from 1630 low-income preschoolers.
• The Child Math Assessment (CMA) was used to evaluate mathematical abilities.
• A Multiple Indicators Multiple Causes (MIMIC) model examined gender differences.

Main Results:

• The best-fitting model identified four distinct factors: Number and Operations, Measurement, Geometry, and Patterning.
• The Number and Operations factor comprised sub-factors of Numbering, Operations, and Relations.
• No significant differences in mathematical abilities were found between male and female preschoolers.

Conclusions:

• Informal mathematical knowledge in preschoolers is a multi-dimensional construct.
• Early mathematical development includes separable dimensions beyond just number and operations.
• Gender does not appear to be a differentiating factor in preschool mathematical abilities.
