Accuracy based testing issues
• If in a testing situation, There is a reward for hitting a target • Students that are high skilled, will go for the outside and thus have more error. • Less skilled an tries to hit the whole net and get more points except.
Testing Motor Ability: predicting human performance. The two different types
• Purpose of analysis • Measure sub domains
Subjective skill tests
• Subjective ratings: scores derived from assessing the form of the movement rather then the (cues) o Golf teacher is a skill analyst o Have a list of critical elements (of form) The absolute need in order to accurately perform. (Ex. BEEF, Balance, Eye's, Elbow, Follow-through)
Repetitive-performance Tests
• Tests that involve continuous performance of an activity for a specified period of time
4 primary Objective tests
• Accuracy-based test • Repetitive- performance tests • Total body movement tests • Distance or power performance o What are these and what are the scoring issues with in each of these tests?
Distance and power tests
• Assess one's ability to project an object for maximum displacement or force.
Total body movement test
• Assess speed of which a performer completes a task at a fast speed
Accuracy based Testing
Involve the throwing or hitting of an object, such as a volley ball or shuttlecock. - Ex. kicking a soccer ball into the net at specific corners
Distance and power tests issues
o Badminton drive test (distance) o Distance throws in softball and baseball o Punt pass and kick competitors • Problems: assuring they are performing the task correctly • If hitting a down the line shot, it is more important for accuracy. • Doesn't matter about the score, but about • Assumption of power, when in fact it is accuracy.
Total body movement Test Issues
o Ex. Dribbling a basketball around obstacles at a fast speed o Flaws: During a game situation you want use max spread, but you need to control you speed. o Reliability: pretty high o Validity: If you measure, make the test very game like.
Different types of Measured Sub Domains?
o Muscular strength, speed, agility, anaerobic power, flexibility, balance, Kinesthetic perception.
Trials to Criteria Tests
o Perform skill until reach a certain criteria... 8 free throws in a row. o (ex. Gives the person the chance to work on another skill, while the others practice their needed skill, free throw shots)
Purpose of Analysis, What is the process?
o Selection, classification, diagnosis, and prediction
Performance Based Test
o Skill classified according to actual performance based on reaching criteria - archery, golf, bowling, swimming. o (ex. Performing golf game)
Issues with Repetitive-performance Tests
o Used to measure strokes of racket sports o High degree of reliability (Important) o Low validity (Important) o Not game-like, may not transfer into actual game performance o Testers make sure that the test subjects use correct form. o Validity, volley in a game to a square on the wall
Global Ratings
score overall performance in a game like context o Players ability to make the correct decision in the correct amount of time. o Ex. Of passing soccer-ball to the person with a defender next to them.
