The consistency of an assessment.
What does reliability measure?
|
Validity
What term is used to measure the accuracy and judgement of a test and make sure that the test measures what it claims to measure?
|
Item Analysis-Allows teachers to modify assessment items.
What is the term used for teachers to increase the reliability and validity of an assessment by reviewing the patterns and scores of past achievments/failures in similar assessment components?
|
Student rankings- making sure students have consistent scores, high or low, on the new and old tests.
What is the key statistical aspect when looking at reliability and validity?
|
It increases the quality of your assessments which will create a more successful classroom and enhance student learning. It also allows the teacher to reevaluate the connections between the material they are teaching and student comprehension of that mat
Validity and reliability are important to know because....

|
Test-retest
What form of checking for reliability requires students to take the same assessment to determine if students' class rankings are being maintained?
|
Criterion-related- Examples of this include the ACT as well as students GPA's because it is compared to established standards.
What form of assessment validity takes students assessment scores and compares it to already established criterion?
|
By the percentage of individuals who correctly answered a given item. If the correct answers on a certain assessment items are below 25% or above 75% they are said to be questionable and should be reevaluated.
How do you measure item difficulty?
|
FALSE!- Educators should constantly be examining their assessments to make them more valid and reliable.
T or F: There is no need to evaluate the reliability and validity of your assessments more than once.
|
We have not yet had any experiences of assessing students but have been assessed ourselves through the ACT and our GPA scores, which checks for criterion-related validity.
Real Life Examples...
|
|
False, In alternate forms reliability students take two equivalent forms of the same assessment.
T or F: In alternate forms reliability, students take two different content based assessments.
|
TRUE- This is based off of an experts judgement.
T Or F: In content validity the material that is presented to students is compared to what is being assessed and ensures that the standards are being met.
|
FALSE! -Item difficulty may be set in a different manner depending on the assessment goals.
T OR F- With item difficulty there is no need to take the assessment procedure into account.
|
Formal Analysis- Bubble sheets and Excel spreadsheets are often used to analyze reliability, validity, and item analysis within assessments.
This type of analysis examines reliability, validity, and item analysis through the use of technology.
|
Many educators are frustrated because NCLB puts limitations on the types of assessments educators can administor which are not always applicable to all students across the country. With NCLB, assessments are very formal and educators aren't allowed to b
Why do you think many educators are frustrated under the NCLB?

|
ONE! This measures the consistency across different sections of an assessment.
How many tests do students take to measure the internal consistency reliability of an assessment?
|
Construct validity- This helps with how to define and measure abstract assessments
What form of validity would you use to assess a critical thinking or problem solving ability?
|
Students who answered the question correctly are in the top group, and the students who asnwered the question incorrectly are in the bottom group. The teacher determines how big the top and bottom groups are.
What is an example of a perfectly differentiated score on a question using item discriminiation?
|
Transform the test scores into class rankings. Teachers can then compare these rankings to get an approximation of reliability and validity.
What is the first step in informal analysis?
|
Good Luck on your Midterm!!!!
Thanks! Hope this helped you to get a better understanding of Quality Control with Assessments!
