Completed Projects



The Supporting Physical Activity in the Childcare Environment (SPACE) study involved implementing a 3-component intervention in childcare centres in London, Ontario and included: 1) new portable play equipment; 2) shorter, more frequent outdoor play sessions; and, 3) staff training in physical activity. The goal of this study was to increase preschoolers’ physical activity levels and decrease their sedentary time during childcare hours.

The purpose of the Learning Environments’ Activity Potential for Preschoolers (LEAPP) study was to compare the physical activity levels (i.e., moderate to vigorous physical activity, total physical activity) of preschoolers in three different early-learning environments (i.e., center-based childcare, home-based childcare and full day kindergarten) and to assess which characteristics (i.e., play equipment, policies, staff behaviour and training, outdoor play periods, sedentary behaviours/opportunities) of these early learning environments were associated with preschoolers' physical activity.

An Examination of Early Childhood Educators’ (ECEs) Knowledge, Self- Efficacy and Risk Tolerance for Outdoor Play among Young Children in Childcare

The purpose of this study was to train early childhood educators to promote children’s frequent engagement in outdoor play with exposure to risk. In partnership with the YMCA of Southwestern Ontario (SWO) an Outdoor Play Workshop was created to 1. inform ECE’s of the importance of risky play for young children and 2. educate participants how to responsibly implement activities involving risky play. Study outcomes measured how the workshop changed ECE’s (1) knowledge, (2) self-efficacy (SE), and (3) risk tolerance for children’s outdoor play in participating YMCA childcare centres.
