Acquisition of skill
Skill and ability
Skill - Learned ability to bring about pre - determined results with maximum certainty and, often with minimum of time, energy or both
Ability - A stable, enduring and mainly genetically determined characteristic that underpins skilled performance and can be used in a variety of skills
Glacear
Goal - directed:intention to do it
Learned: repeated practice and experience
Aiming to achieve
Consistent: executed with maximum certainty
Exellent performance: of a high quality
Aesthetic on the eye: controlled and effective
Recognisable: techniques can be named and compared
Classification of motor skills
Three types of skills:
Intellectual skill - skills which involve the use of a person's mental powers - include problem solving and verbal reasoning
Perceptive skill - Involves making sense of information coming in via our senses - analysing your own location, others on the field, flight of the ball, decision making pass or run
Mental skill - Physical movements and muscular control - passing
Gross - large muscle movements - large muscle groups - major bodily movement skills
Fine - small muscle movements - small muscle groups - small bodily movements
closed - not affected by the environment - stable and predictable - internally paced - stereotypical movements
open - affected by the environment - unstable and often unpredictable - externally paced - variations of skill needed - often movements require adjustment
Discrete - clear beginning and end - single skill e.g golf swing
serial - number of discrete skills put together e.g triple jump
continuous - unclear beginning, middle and end e.g cycling
internally paced - at your own pace - choose when movement starts e.g shot put
externally paced - control is not determined - involves the performer reacting
simple - low number of decisions to make - small info to process - time to evaluate the situation e.g swimming
complex - many decisions required - large amounts of info to process - shot amount of time to evaluate the situation e.g gymnastics
low organisation classification - parts of the skill can be separated and practised - sub - routines can be identified e.g serve in tennis
high organisation classification - difficult to spot individual parts - often needs to be practised e.g golf swing, cycling
Characteristics of ability
Ability - inherited and enduring trait that underlines or supports various kinds of motor or cognitive activities or skills. they are genetically determined
Abilities are...
stable and enduring
genetic, inherited traits
crucial for underpinning skills and abilities
NINE MAJOR GROSS MOTOR ABILITIES
dynamic strength - exerting muscular force repeatedly over a period of time
static strength - maximum strength that can be exerted against an external object
explosive strength - energy used effectively for a short burst of muscular effort
trunk strength - the strength of the abdominal muscles
extent flexibility - flexing or stretching the trunk and back muscles
dynamic flexibility - being able to make several rapid flexing movements
stamina - the capacity to sustain maximum effort involving the cv system
gross body co-ordination - the organisation of the actions of several parts of the body whilst the body is moving
gross body equilibrium - being able to maintain balance using the internal forces
EIGHT EXAMPLES OF PSYCHOMOTOR ABILITIES
multi limb co-ordination - being able to organise the movement of several limbs at the same time
response orientation - choosing quickly to the position which an action should be made
reaction time - being able to react quickly to a stimulus
speed of movement - being able to make a gross motor movement
finger dexterity - being able to work with tiny object using the fingers
manual dexterity - being able to make accurate arm/hand movements involving
rate control - being able to change the speed and direction of responses accurately
aiming - being able to aim accurately at a small object
Three States of Learning
cognitive phase
initial phase of learning process
mental picture - demo and verbal explanations
more complex - take long to learn
small chunks of info given
How can we aid beginners?
demo
simple verbal instructions
trial and error
specific equipment
Associative phase
significantly longer
start to eliminate mistakes
refine skills
sub-routines,co-ordination are smoother and flow
motor programmes are developed
skills are practised and refined
use of internal and kinaesthetic feedback
Autonomous phase
become automatic
minimum concious thought needed
autonomous characteristics
automatic
preformed without stress
little concious control
habitual
becomes GLACEAR
can be adapted
advantages of autonomous phase
motor programme is now grooved
concentrate on other aspect
increase self confidence
improvements in performance are now much slower
Methods of manipulating motor skills
part practice
break down skill into parts and practice them individually
Advantages
perfect for high complex and serial skills
disadvantages
takes a long time
can't use for things like diving - continuous, complex skill
whole practice
skills are taught as a whole movement
perfect for high organisation and highly complex skills
advantages
helps the learner to understand the movement
disadvantages
not suitable for complex or dangerous skills
progressive part practice (A,B,C/A,B/A,B,C)
skill is practised in parts
advantages
good for complex skills
good for skills low in organisation
disadvantages
not suitable for skills high in organisation
whole part whole method
skills are taught as a whole skill
coaches identify areas to work on
skill is then done as a whole
advantage
get the feel for the skill
quicker than part skill
disadvantages
not suitable for highly organised or dangerous skills
Types of guidance
visual guidance
most effective at cognitive phase
