Our guest today is Associate Professor Lynn Barnett-Morris from the University of Illinois at Urbana-Champaign. For the last three years she’s been researching Kindergarten-aged children to determine how playfulness in the classroom is viewed by the children themselves, their classmates and their teachers. The result – a longitudinal study titled 'The education of playful boys: class clowns in the classroom'. She joins The Research Files today, on a bit of a scratchy line from the US, to discuss the key findings, but to kick things off, I ask Lynn to tell listeners why she decided to conduct this research in the first place.
