Observing and assessing role play in early childhood: evaluation of the Play Matrix tool

This study evaluates the Play Matrix, a novel observational tool designed to assess role-play in early childhood within the cultural-historical framework. The Play Matrix comprises 22 behavioral indicators across actions, speech, and emotional expressions. We examined its reliability and validity by analyzing video recordings of 42 children aged 5-6 years in both free play and adult-facilitated play settings. High inter-rater reliability was observed for most indicators, and significant differences in play behaviors between children with high and low levels of self-regulation were detected. Children with lower self-regulation exhibited more impulsive actions, expressive gestures, and involvement in emotionally rich group actions. Additionally, to validate the Play Matrix as a tool for analyzing the nuances of play situations, play behaviors in different play situations was compared. It was noted that children in free play show more unscripted character actions, speech in the play context, and more often regulate the behavior of other children. The Play Matrix offers a comprehensive mechanism for capturing the developmental potential of play, providing valuable insights into early childhood development.
