"How much do I know?": Children's evaluations of their absolute and relative knowledge

Area of Science:

• Cognitive Development
• Metacognition
• Child Psychology

Background:

• Understanding how children assess their own knowledge is crucial for effective education.
• Distinguishing between absolute (self-based) and relative (expert-comparison) knowledge evaluation is key.
• Previous research has explored children's metacognitive abilities with varying methodologies.

Purpose of the Study:

• To investigate the relationship between children's absolute and relative knowledge evaluations.
• To examine how children's knowledge judgments differ for common versus uncommon topics.
• To explore age-related changes in children's self-assessment of knowledge compared to experts.

Main Methods:

• 148 children aged 6-10 years participated.
• Participants completed measures of absolute and relative explanatory knowledge on common and uncommon animals and vehicles.
• Knowledge judgments were assessed in relation to self-knowledge and expert knowledge.

Main Results:

• Children's absolute and relative knowledge judgments were strongly correlated.
• Children consistently rated their knowledge higher for common items than uncommon items.
• Relative knowledge ratings decreased with age, and high self-raters still acknowledged expert superiority.

Conclusions:

• Children's self-assessment of knowledge is influenced by both internal standards and external comparisons.
• Awareness of knowledge gaps relative to experts develops with age.
• Findings have implications for instructional strategies and fostering accurate metacognition in children.
