Chapter 14 Standardized Tests and Teaching Flashcards
Standardized test
Commercially prepared test that assesses student performance under uniform conditions
Minimum competency tests
Tests that assess skills that students are expected to have mastered before they can be promoted to the next grade or permitted to graduate
High-stakes testing
Testing in a way that has important consequences for the student
Norm group
Group of similar individuals who previously had been given a test by the test maker
National norms
Norm group that consists of a nationally representative group of students
Special group norms
Norm group that consists of test scores for subgroups from a national sample
Local norms
Norm group that compares student performance within same class, school, or board
Reliability
The extent to which a test produces a consistent, reproducible measure of performance
Test-retest reliability
The extent to which a test yields the same performance when students complete the same test on two different occasions
Alternative forms reliability
Providing different froms of the same test on two different occasions to the same group of students to determine how consistent the scores are
Split-half reliability
Dividing test items into two halves, and comparing the two sets of scores to determine how consistently students performed across each set
Validity
The extent to which a test measures what it is intended to measure and whether the test scores are used accurately
Content validity
A tests ability to sample the content that is to be measured
Criterion validity
A tests ability to predict student performance as measured by other assessments or criteria
Concurrent validity
The relation between test scores and other available criteria
Predictive validity
The relation between test scores and a students future performance
Construct validity
The extent to which there is evidence that a test measures a particular constuct, that is, an unobservable trait or characterisitc of a person
Instructional validity
The extent to which an assessment is a resonable sample of the classroom practice
Aptitude test
A test used to predict a students ability to learn skills or accomplish tasks with further education and training
Achievement test
Test that measires acquired knowledge and/or skills
Psychoeducational assessment
Assessment that comprises teo general test batteries:
1) aptitude 2) achievement
Survey battery
Group of individual subject-matter tests designed for students at a particular level
Diagnostic tests
Achievement tests that measure select skills in a specific subject area with the purpose of diagnosing an individuals relative strengths and needs.
Descriptive statistics
Mathematical procedures that are used to describe and summarize data in a meaningful way
Frequency distribution
Listing of scores, usually from highest to lowest, along with the number of times each score appears
Histogram
Frequency distribution in graph form
Measure of central tendency
Number that provides informaiton about the average or typical score in a set of data
Mean
Numerical average of a group of scores
Median
Score that falls exactly in the middle of a distribution of scores after they have been arranged from highest to lowest
Mode
Score that occurs most often within a distribution of scores
Measures of validity
Measures that indicate how much scores vary from one another
Range
Distance between the highest and lowest scores
Standard deviation
Measure of how much a set of scores varies on average around the mean of the scores
Normal distribution
When most of the scores cluster around the mean
Raw score
Number of items a student answers correctly on a test
Percentile rank score
Reveals the percentage of the distribution that lies at or below the score
Stanine score
Describes a students test performance on a nine-point scale ranging from 1 to 9
Grade-equivalent score
Represents a students achievements in terms of a scale based upon grade and month in school
Standard score
Score expressed as a deviation from the mean
z-score
Data that provides infromation about how many standard deviations a raw score is above or below the mean
T-score
Standard score in which the mean is set at 50 and the standard deviation is set at 10
Percentile rank
Range of scores around a mean value expressed in percentiles
