Skill acquisition Flashcards
What is a skill
Learned ability to bring about predetermined results with the minimum outlay of time and energy
Characteristics of a skill
Aesthetically pleasing
Consistent
Efficient
Fluent
Accurate
Controlled
Economical
Open skill
Environment is unpredictable and changes frequently
Eg passes in a game
Closed skill
Predictable environment, doesn’t have to adapt actions
Eg shot put
Gross skill
Performed using large muscle groups
Eg shoulder muscles used in a rugby tackle, with leg muscles used to drive to the ground
Externally paced skill
No control over when to start the drill or how fast it will be performed
Eg sailor must react to speed of wind
Fine skills
Smaller more intricate muscle groups
Eg the control needed to return a shot in table tennis
Self paced skill
Control over the speed skill is performed
Eg footballer taking a penalty
Discrete skill
Clear beginning and end and is 1 short action
Eg tennis serve
Continuous skill
no clear beginning or end but is more a cycle of movements repeated over and over again
Eg cycling
Serial skill
Several discrete skills are linked together to complete a task
Eg dance, gymnastics
Low organised skill
Skill easily broken down into its sub- routines
Eg swim strokes
High organised skill
Not easily broken down into parts
Eg volly in football
Simple skill
Limited decisions
Eg forward roll (gymnastics)
Complex skill
Decisions may need to be made before skill is attempted
Eg dribble in hockey x where are players, ball
Types of transfer
Positive
Negative
Zero transfer
Bilateral transfer
Positive
Learning of one skill helps /aids the learning of another
Similar shape/ form
Eg over arm volleyball serve + tennis serve
Negative
Learning of 1 skill hinders the learning of another
Some similarity with environment may cause confusion
Eg badminton and tennis
Zero transfer
Learning 1 skill has no impact on learning of another
Eg swim action and foot placement for rock climbing
Bilateral transfer
Learning of one skill is passed across the body to limb to limb
Eg footballer (right-footed) being taught to use their left foot
Methods of presenting practise
Whole practise
Whole-part practise
Progressive part practise
Whole practice advantages
A feel for the whole skill
Sub- routine linked fluidly
Realistic to performance
Whole practice
Practising skill entirely, not breaking off into sub-routines
Skill is simple and doesn’t require much thought
Whole practice disadvantages
Difficult for cognitive learners who may find the demands of the whole skill too much
Fatigue and boredom could result
Whole part practice advantages
Provides immediate feedback
Motivation technique when weaknesses are corrected
Whole -part practice
Assessing the skill, identifying a weakness to practise then putting the skill back together
Breaking down complex task into stages
Whole part practise disadvantages
Can lead to negative transfer if sub-routine is not integrated back into whole skill
Time consuming
Progressive part practise
First part of the skill is taught then the rest are added to the sequence
Progressive part sequence advantages
Can focus on 1 part of a serial skill and correct errors
Successful parts can maintain motivation to learn the whole skill
Progressive part sequence disadvantages
Time consuming
Could lead to negative transfer of parts not learnt correctly
May need to rest
Types of practise
Massed
Distributed
Varied
Mental
Massed practise
- No rest intervals, continuous
- Skill is simple, environment is closed
- basketball player practicing free throw
massed practice advantages
- promotes fitness so performer can keep up with demands of the tasks
- practicing without break
massed practice disadvantages
- can produce fatigue
- danger of negative transfer unless coach makes practice similar to match
Distributed practise
- Resting between sessions
- when skill is continuous
- open skill
- swimmer practicing stroke
distributed practice advantages
- takes pressure off the performer and allows recuperation after tough session
- good for beginners since it allows controlled process and coaching advice
- motivation - praise from coach
distributed practice disadvatage
- time consuming - not used when skill requires fast progress
- not useful for expert players
- danger of negative transfer
