Unformatted text preview: C. Motor Skill Classiﬁcation Systems
Determine which components of a skill are common or similar to components of another skill.
For each classiﬁcation system, consider each of the two categories as extreme ends
of a continuum. #1. Based on precision of movement:
This classiﬁcation system is most commonly used in special education, adapted
physical education, and rehabilitation. Gross motor skills - involve large musculature as the primary basis of movement -
walking, throwing, jumping, most sport skills . While precision of movement is not an important component, the smooth
coordination of movement is essential to the skilled performance of these tasks. Fine motor skills - skills that require the ability to control small muscles of the
body in order to achieve the successful execution of the skill. Generally, these
skills involve hand-eye coordination and require a high degree of precision of
movement - writing, drawing, piano playing, watchmaking Physical therapists usually work with gross motor skills while occupational
therapists work on ﬁne motor skills. #2. Based on distinctiveness of beginning and end points of the movement:
This classiﬁcation system is most commonly used by motor learning researchers
and in human engineering and human factors. Discrete motor skill - clearly deﬁned beginning and end points - throwing a ball,
pushing in the clutch in a car, hitting a key on a computer Discrete skills can be put together in a series - serial motor skills - starting a
standard transmission automobile, a dance routine, shooting an arrow in archery.
Each skill consists of a speciﬁc series of movements that must be performed in a
speciﬁc order for proper execution of the skill. Continuous motor skill - have arbitrary beginning and end points. The performer
or some external force determines the beginning or end point of the skill rather
than the skill itself - steering a car, tracking tasks such as using a pursuit rotor,
swimming, running, etc. ...
