This practicum report describes an intervention designed to increase opportunities for children in a day care center and preschool to practice gross motor skills, and to help teachers gain confidence in their ability to foster children's maturation. It was expected that as a result of the intervention, 50 of 70 children would participate in gross motor outdoor play on a daily basis, and that 5 of 7 teachers would plan gross motor experiences and playground activities for children. The 12-week intervention involved: (1) improvement and acquisition of playground equipment; (2) provision of gross motor lesson plans and a reference list about gross motor play; (3) an in-service training session on child and gross motor development; (4) teacher meetings with the center director for planning a gross motor curriculum; (5) a newsletter to parents describing the intervention; and (6) teacher meetings to discuss problems and successes in the program. Outcomes were measured by pre- and postintervention teacher surveys and observations of children. Observations indicated that more than 50 children participated in gross motor outdoor activities on a daily basis. All teachers gave an above-average response to survey indicators that measured their perceptions of their own level of training and ability. Twelve appendices include various forms and planning guides used in the intervention and other relevant materials. (BC)
