WGU D184 EXAM TEST PAPER WITH
DETAILED QUESTIONS AND RELIABLE
ANSWERS
◉ Mounting Evidence
Answer: Use multiple indicators to find patterns of student
achievement and determine summative scores
◉ Linear trend
Answer: Math model in which it's assumed there is a steady and
equal increase in learning over time.
◉ Curvilinear Trend
Answer: Assumption that when initially learning something,
students demonstrate rather large jumps but over time. Increase
flattens out
◉ Average
Answer: The assumption that no learning occurs from assessment
to assessment
( looks like a straight line on a bar graph)
Students scores are combined and averaged
◉ True score
, Answer: An estimation of a students actual score on an
assessment if there was no error. Are considered accurate
measures of student knowledge although efforts should be made
to reduce errors. Represents students true level of understanding
◉ Observed score
Answer: true score + error score
◉ Error score
Answer: The part of the observed score that is due to factors other
than the students level of understanding
◉ Best fit model
Answer: The model with the least amount of error ( in regards to
mathematical models)
◉ Proficiency Scales
Answer: Measure student achievement of knowledge and skills in
standards over time.
◉ Half Point Score Values
Answer: Used in proficiency scales for mastery at one level, but
does not meet all of the criteria for the next level.
◉ Generic Scale
