This document discusses two approaches to assessing fundamental motor skills - the whole body approach and component approach. The whole body approach examines all body parts together in stages of development, while the component approach breaks skills down into individual body parts that may develop at different rates. The author analyzes videos of children performing jumping and catching skills and predicts their development level using both approaches. Their predictions were accurate based on the videos. Both approaches are useful for analyzing motor skill development, but the component approach may be more beneficial as it acknowledges skills can mature separately.
