The document discusses how teachers can contribute to developing executive functions in children through motor activity. It summarizes research showing that activities like aerobics, yoga, martial arts, and exercising bimanual coordination can improve executive functions. The study described in the document examines the effects of 10 weeks of playground motor activities on 4-5 year olds, with an experimental group receiving encouragement from teachers during activities. Preliminary results show improvements in motor skills and executive functions like inhibition and planning for the encouraged group. The study suggests structured motor activities and teacher involvement can effectively support child development.
