Fundamental skill development is such an important part of my profession, this is because it provides a base for other skills to develop from. If a child never learns how to properly kick a soccer ball how can they be expected to perform a perfect corner kick. There is no way to expect that from someone, there are certain skills that must be learned in order to learn skills that are more complicated. An assessment is needed to insure that the child can perform the simpler tasks before trying to perform a harder one, this helps to make sure that the child will not be injured. In gymnastics before a child can attempt to perform a front handspring a handstand must first be mastered to insure that the child will not be injured.
The American Alliance for Health, Physical Education, Recreation and Dance (AAHPERD) provides excellent reasons why Physical Education is such an important part of schools and why it helps children.
This website provides many good statistics and data for Physical Education.
Here is an image from www.google.com showing one way to spot a handstand.
This is a young girl who performs the front handspring and she stresses the straight arms and the handstand before doing the rest of the handspring. The video is from www.youtube.com
