What is a placement assessment?
A placement assessment determines prerequisite skills, degree of mastery of course goals, and/or
best mode of learning. Illustrative examples used are readiness tests, aptitude tests, pretests on
course objectives, self-report inventories, and observational techniques.
Define formative assessment and give examples of illustrative instruments.
Formative assessments determine learning progress, provide feedback to reinforce learning, and
correct learning errors. Examples include teacher-made tests, custom made tests from textbook
publishers, and observational techniques.
Define diagnostic assessment and give examples.
A diagnostic assessment determines causes (intellectual, physical, emotional, or environmental) of
persistent learning difficulties. Examples include published diagnostic tests, teacher-made diagnostic
tests, or observational techniques.
Define summative assessment and give examples.
Summative assessments determine end-of-course achievement for assigning grades, or certifying
mastery of objectives. This could be a final exam or final project. Illustrative examples include teacher-
made survey tests, performance rating scales, or product scales.
What is the difference between norm-referenced and criterion-referenced methods of interpreting
results?
When scores are criterion referenced, they describe student performance according to a specified
domain of clearly defined learning tasks. For instance, could the student multiply two-digit whole
numbers? However, when scores are norm-referenced, they describe student performance according
to the relative position in some known group For instance, the student ranks 8 in a class of 22
students.
What is validity?
Validity is an evaluation of the adequacy and appropriateness of the interpretations and uses of
assessment results. It answers the questions (1) to what extent will the interpretations of the scores
be appropriate, meaningful and useful for the intended application of the results? and (2) what are
the consequences of the particular uses and interpretations that are made of the results?
What is a correlation coefficient?
A correlation coefficient provides a numerical summary of the degree of relationship between the two
sets of scores. For example, the relationship between a tenth grade math final and SAT math scores
could be used to determine a correlation coefficient.
What is a scatterplot?
A scatterplot illustrates the different degrees of positive relationship between a predictor and a
criterion.
What is reliability?
