Core 2: Factors affecting performance FQ3 How does the acquisition affect performance? Assessment of skill and performance
Syllabus outcomes Learn about Learn to Assessment of skill and performance Characteristics of skilled performers, eg Kinesthetic sense, anticipation, consistency, technique Objective and subjective performance measures Validity and reliability tests Personal versus prescribed judging criteria Develop and evaluate objective and subjective performance measures to appraise performance
Characteristics of skilled performers The difference between a skilled and an unskilled performer is made by a study of specific practical performance. A skilled performer seems to ‘have all the time in the world, has smooth perfectly timed movements and does the right thing at the right time’ Characteristics include: A kinaesthetic sense: or feel of how well the skill was performed. For example the diver feels that the dive went well. Anticipation: A skilled performer can ‘read’ a game by anticipating aspects of the game using selective attention and perception, for example, an intercept in ball sports is an example of anticipation Timing: skilled performers can react, move and respond quickly to stimuli. Reaction time: is the time between the ball being thrown and the batter’s first movement Movement time: is the time between the first movement occuring and the movement being completed (hitting the ball) Response time: is the total time taken to act and complete the movement
Characteristics of a skilled performer Mental Approach A skilled performer uses mental rehearsal to visualise a good performance. Arousal not too much or too little, confidence and concentration all contribute to the control necessary for a skilled performance. Consistency A skilled performer gives a consistent performance.
Objective and subjective performance measures Objective measurement Is when judges reach the same conclusion, and there is no disagreement as the method of measurement are obvious to the observer. Examples: electronic timing devices stopwatches competitor placings photo finish Archery Pistol Shooting Ten pin bowling
Subjective Measurement is personal and based on the opinions or impressions of judges rather than on objective measurement Judging the quality of a performance is also termed appraisal, or appraising the performance.
Validity and reliability tests When measuring skill, the test must be valid, that is designed to measure what its purpose is to measure. The test must be reliable, consistent and precise so that similar results are obtained when the next test is given.
Personal versus prescribed judging criteria based on the judges impressions, opinions or feelings about the performance Examples Scoring a dance routine commenting on a front rowers game form Prescribed Makes a personal observation more creditable by using methods such as rating scales and checklists These are perspectives and more reliable than a personal observation. The front rower made 20 Hit-ups and 30 tackles Dance criteria eg. Year 11 assessment task
