Intervention
EYE, FMS
Stencils were spray painted onto an open concrete area within the outdoor play setting for preschoolers (ages three to six years) at the ECE center. Stencils were purchased from Fast Line Striping Systems (Kingston, Ontario, Canada) including Sunflower Hopscotch (US $159), Bull’s Eye (US $179), and Mirror Me (US $149; See Figs.

Bull’s Eye StencilA toolkit (written booklet) was developed that provided childcare center staff with step-by-step instructions and photos to describe developmentally appropriate activities/games for their students during play using the stencils. With the toolkit, an expert (EKW) in motor skill development and PA in pediatric populations and two school physical education teachers developed a short video (11 min) for ECE center staff. This video included information on the importance of FMS as well as strategies/games and examples for using the playground stencils. The videos included preschool-aged children modeling how to use the stencils, to help teachers utilize the stencils during outdoor time to help children perform appropriate movements and facilitate the execution of proper FMS. The video and written toolkit complement each other to provide a complete package for ECE center staff to use stencils appropriately and easily during outdoor play to encourage safe and fun activities for preschool children with limited to no additional equipment required.Thirteen printed toolkits were delivered to the two intervention ECE centers so that each teacher and director would have their own copy during the intervention period. The video was delivered to intervention ECE centers on a jump drive and was also sent to each director electronically via email with a link directly to the toolkit video on a private YouTube channel. The director was asked to watch the video and share it with all preschool teachers. A study staff member spent a total of approximately two hours at each intervention ECE center (spread across two to three visits) to meet with the director and lead teachers to explain the project, to present the video to the teachers, and to answer questions. The staff member also provided contact information to the teachers in case they had questions. After data collection ended, the study staff painted the same stencils on the playgrounds of the control ECE centers and also distributed toolkits and the video to the staff of the control centers.
