Number gestures predict learning of number words

Area of Science:

• Child Development
• Cognitive Science
• Educational Psychology

Background:

• Children often use gestures when explaining solutions, sometimes conveying information distinct from speech.
• Gesture-speech mismatches indicate potential for learning, particularly when gestures contradict speech.
• Contradictory numerical mismatches signal readiness for targeted number-word instruction.

Purpose of the Study:

• To investigate if contradictory numerical gesture-speech mismatches predict learning gains from number-word instruction.
• To determine the effectiveness of different instructional approaches for early number learners exhibiting these mismatches.

Main Methods:

• Assessed number knowledge using the Give-a-Number task.
• Identified gesture-speech mismatches using the What's on this Card task.
• Randomly assigned early number learners to Counting or Enriched Number Talk conditions.

Main Results:

• Children with numerical gesture-speech mismatches profited more from the Enriched Number Talk condition.
• The Enriched Number Talk condition led to greater learning of new number words compared to the Counting condition for these children.
• Gesture-speech mismatches were a reliable predictor of learning outcomes.

Conclusions:

• Numerical gesture-speech mismatches serve as a key indicator of a child's readiness for advanced number instruction.
• Cardinal number gestures play a significant role in the process of number learning.
• Rich, multi-component number instruction is more effective for learners who exhibit these specific mismatches.
