Abstract
The purpose of this study is to evaluate the effectiveness of a mixed aged kindergarten play activity by observing the behavior of its participants. Two groups of children; pre-kindergarten-aged children (PKC) and 5 year-old children (5YO) were each paired and guided to participate in an activity. Behavior and speech of both parents and paired groups were observed and recorded for analysis by M-GTA. A range of interactions between parents and 5YO were recorded which inferred much about parents' emotional responses, commitment to participation and their understanding of child development. By examining the results chart it was possible to speculate on ways to improve the play activity and gain a better understanding of what characteristics are required to make a successful play program in the future.
