Testing & Measurements Vocab Flashcards
validity
refers to how accurately a method measures what it is intended to measure
formative assessments
monitor student learning to provide ongoing feedback that can be used by instructors to improve their teaching and by students to improve their learning
interim assessments
determine student achievement on standards
IDEA
Individuals with Disabilities Education Act
NCLB
No Child Left Behind
standards-based reform
arose in response to the release of “A Nation At Risk” in 1983 & evolved into two general themes or strands: academic standards and performance standards
RTI
Response to Intervention- tiered system designed to integrate assessment, research-based instruction, and data-based decision making to improve educational outcomes in all classes
positively skewed distributions
results from an asymmetrical distribution of scores
negatively skewed distributions
results from an asymmetrical distribution of scores, but majority of scores fall above the middle of the score distribution
performance tests
tests that use direct measures of learning rather than indirect measures that simply suggest cognitive, affective, or psychomotor processes that have taken place
holistic scoring
used when the rater is more interested in estimating the overall quality of the performance and assigning a numerical value to that quality than assigning points for the addition or omission of a specific aspect of performance
rating scales
used for those aspects of a complex performance that do not lend themselves to yes/no or present/absent type judgments
measures of central tendency
mean, median, mode
standard deviation
includes all the scores in a distribution in its computation; normally reported as the estimate of variability that accompanies the mean in describing a distribution
validity
does the test measure what it is supposed to?
reliability
refers to the consistency with which it yields the same rank for individuals who take the test more than once
Kuder-Richardson Method
measure the extent to which items within one form of the test have as much in common with one another as do the items in that one form with corresponding items in an equivalent form
standard error of measurement
the standard deviation of the error scores of a test
test-retest
coefficients are determined over a short period of time and few changes are likely to take place within students to alter their test scores
alternate forms
determined by administering two different forms or versions of the same test to the same group close together in time
