Unit One

1. 1. Unit One …Intro to Motor Skills & Abilities 2.

2. Chapter1 …Classifying motor skills

3. Terminology… • Skills, Actions, Movements • Skills = Actions • These are goal directed movement activities (“family of movements”; “equivalence class”) • Movements • Actual limb configurations used to achieve the action/skill • Differ from person to person, and within skill • Examples? • See “a closer look” on p. 4

4. Classification…gross/fine • Size of musculature required • Gross motor skill – large musculature • Fine motor skill - small musculature

5. Classification…gross/fine • Size of musculature required • Used a lot in special ed. & adapted PE • Some motor deficits are more noticeable with a particular type of skill • Examples?

6. Classification…discrete/cont. • Specificity of action’s beginning and end • Discrete motor skill • Serial motor skill • Continuous motor skill

7. Classification…discrete/cont. • Specificity of action’s beginning and end • Used often to help analyze how a skill is controlled • Discrete – controlled more by planning • Continuous – controlled more by feedback • Examples?

8. Classification…open/closed • The stability of the environment (environment refers to object acted on or performance context) • Closed motor skill – unchanging environment • Open motor skill - changing environment

9. Classification…open/closed • The stability of the environment (environment refers to object acted on or performance context) • Also used to help analyze how a skill is controlled • As the skill becomes more open, it is increasingly likely to be reliant on feedback • Examples?
