Validity
What is validity?
Mr. Brown creates a science test based on the science standards covered in class the past two weeks, depicting this type of validity.
What is content validity?
Ms. Fisher gives a universal math screener every two weeks that produces similar results for students each time, representing this term.
What is high reliability?
Ms. Egleston has Tommy take the same science test twice in two days; his scores are almost the same, depicting this type of reliability.
What is test-retest reliability?
Mrs. Boseman saw her students’ achievement on a reading comprehension quiz and assumed that students who struggled on the quiz will also struggle understanding more difficult texts, depicting this term.
What is inference or interpretation?
Tasha's SAT math results indicate she will have success in a STEM field career in the future, depicting this type of validity.
What is predictive validity?
Mr. Ivy's test results varied greatly depending on whether his students took the test during 1st period or 7th period, depicting this.
What is low reliability?
The same group of students take the STAR Math test in early August and a similar version of the test again in late August; the results are similar and have a high correlation, depicting this type of reliability.
What are parallel-forms reliability?
Mrs. Thompson evaluates Stella's presentation for her class and gives her a certain number of points for different categories using this evaluation tool.
What is a rubric?
Ms. Greene briefly glances over an ELA test and says it looks like it does a good job of assessing reading comprehension, depicting this type of validity.
What is face validity?
Ms. Jones sees that most students' test science scores are similar, resulting in a low measure of this. If students scores varied greatly instead, it would be a much higher measure of this.
What is standard deviation?
A 20 question algebra test is given to students; the teacher compares the results of the test's odd questions and even questions and determines a high correlation, depicting this type of reliability.
What is split-half reliability?
Mrs. Carswell maintains that the district should choose an assessment instrument that covers reading skills (fluency, reading comprehension, etc.) taught during the school year to measure students' reading ability, depicting this term.
What is validity argument?
Ms. Cunningham's new Georgia studies test results exhibit strong correlation with the district assessment results; both assessments were taken at the same time, depicting this type of validity.
What is concurrent validity?
Bella correctly answers 40 out of 50 questions on a test. If Bella takes the same test again and correctly answers about the same number of questions (give or take a few), her results depict this indicator of consistency.
What is standard error of measurement?
Mr. Devon creates an art assessment; from the results, he finds that Cronbach’s alpha is high (>.80), depicting this type of reliability.
What is internal consistency reliability?
Mrs. Smith changes her science instruction this week based on her students’ pop quiz results from last week so she can reteach her students the topics they did not understand, depicting this term.
What is instructional sensitivity?
An ELA test that measures reading comprehension has weak correlation with a math test that measures a student's ability to solve equations, depicting this type of validity.
What is discriminant validity?
Students take two alternate and parallel forms of a math exam over two consecutive days. 85% of the students either pass or fail both times, yielding a 15% measure of this.
What is the decision-consistency index?
Mrs. Barker gives a 10 question test over volumes of 3D shapes on Wednesday; she gives a 10 question test over volumes of 3D shapes on Friday. Tests have different questions, but all are multiple choice and have medium difficulty. Both tests produce similar results, depicting this type of reliability.
What is alternate form reliability?
