My name is Pim Koolwijk. I am currently working as a lecturer and researcher at the Hague University of Applied Sciences, participating in a research group on Healthy Lifestyles in a Supporting Environment. I have a degree in PE and human movement science (VU, Amsterdam). My field of interest is the motor competence of young children, physical activity, and physical education. I am completing my PhD in motor competence development and its determinants in children aged 4–6 years old.
