Russell exam 2 Flashcards
Validity
is the degree of truthfulness or accuracy of a test – does the test measure what it says it does?
Reliability
is the degree to which an assessment provides consistent, repeatable results
Objectivity
the degree to which a test yields similar results across different test administrators and conditions
Examples of Influences that can affect validity:
Criterion measure- Actual participation, a panel of expert judges, known valid criterion/“gold standard”
Nature of participants- male/female, old/young
Length of test
Examples of Influences that can affect reliability:
Environment
Similarity of testing period
Instrument precision
Practice
Reliance on another’s performance- the ability to catch a forward pass in football.
Time between testing
Examples of Influences that can affect objectivity:
Understanding the score system
Knowledgable test administrators
Consistency of scoring performances
relationship between validity, reliability, and objectivity
Both objectivity and reliability are prerequisites to validity; a test can be reliable but not valid
Authentic assessment
emphasizes taking the test in a ‘real world setting’.
Game-like, applies skills, cognitive engagement.
Authentic Assessment vs. Traditional Assessment
Traditional forms of assessment are often poorly matched to the material that has been taught or don’t measure what the tester intends to measure. Traditional testing is standardized and centered around skills and written tests while authentic assessments apply testing to the real world for a more translated assessment.
Holistic Rubrics
assessment as a whole; ability to play the game.
Rather than assessing a single skill like serving in VB, the teacher wished to evaluate the student’s ability to play the game.
Analytic Rubrics
a particular skill is evaluated
Kicking a soccer ball, dribbling a basketball, or serving a VB
Holistic vs Analytic rubrics
Holistic assessment is more complex and authentic than analytical assessment.
Purpose of developing rubrics for authentic assessment:
Help teachers define excellence and plan how to help students
Communicates to students what constitutes excellence and how to evaluate their own work.
Communicate goals and results to parents and others
Accurate, unbiased, and consistent scoring
Document procedures used in making important judgments and students.
Steps for Developing a Rubric:
Discriminate among performers in a valid way
Rely on descriptive language rather than comparative
Provide useful discrimination- “needs improvement” rather than “F”
Emphasize the finished product-
Checklist
detects the presence or absence of the desired behavior
yes/no response; straightforward
Rating scale
determine the degree to which a desired behavior has been observed
Rating scale
4- student executes all skills with good form and accuracy
3- student executes skills with good form
2- Student executes few skills with good form
1- Student rarely uses good form
Importance of flexibility assessment
ROM is directly related to muscular strength and endurance
Active
ROM is created by a person contracting muscles around the joint being assessed.
Passive
ROM is created by external force pushing body part around the joint (ex: partner, PTA, piece of equipment)
Linear
is focused on how far a joint/body part is able to move in a linear direction (S/R test)
Rotary
is focused on how a joint performs in angular capacity (shoulder rotation)
Relative
how the body compensates for stiffness in one area by moving more in a neighboring, more flexible area; is focused on assessing flexibility RELATIVE to a body dimension/location
Absolute
maximum range of motion a joint can achieve; is focused on stretched distance without considering body dimension/location
