Drawing on data collected for a larger study investigating kindergarten teachers' online discussions of play, the present qualitative study examines teachers' discussions of gender. Findings suggest that teachers' project onto their kindergarten students many of their own gender prejudices about play. These teachers reinforced gendered attitudes by encouraging the children, especially the boys, to play only with toys and in activities traditionally associated with their gender. Email interviews were then conducted with seven kindergarten teachers to further explore the main theme from the netnographic research. Findings support the contention that further research is needed to examine gendered play in kindergartens, and that kindergarten teachers could benefit from becoming aware of their unintentional teachings and in learning how better to encourage gender equity in play-based class activities.
