InterPLAY: A Framework to Describe Play and STEM Engagement at Exhibits for Young Children

Curator: The Museum Journal, Volume 69, Issue 4, Page 489-506, October 2026.
ABSTRACT Play‐based STEM learning at exhibits is a feature of children's museums and science centers; yet little is known about how these exhibits support young children's STEM engagement. This study developed and tested the interPLAY Framework to describe play‐based STEM engagement at exhibits for young children.
