principles of language assessment - exam 1 Flashcards
purposes of assessment
identification / screening (not diagnostic, determines who needs further evaluation)
evaluation & assessment –> diagnosis, eligibility, goals / outcomes for intervention, monitor progress
prevention
zone of proximal development
framework to decide reasonable next goal
will be able to achieve w/ support
tasks at the limit of the learner’s abilities
Norm referenced assessment
where is the child in the distribution compared to same-chronological-age peers
delays & disorders determined by score/percentile cut off
efficient to administer
must be culturally & linguistically appropriate
does not identify specific intervention targets
criterion referenced assessment
list of skills
what are the discrete skills a child can demonstrate in a specific domain
compared to standard or predetermined criterion
intervention goals setting
simple to score
protocols not always well defined
dynamic assessment
not only what they know, but how they learn
how does the child respond to learning opportunities
adaptive assessment approach
identifies zone of proximal development
useful for distinguishing difference vs disorder
assessment applications
combo of assessment procedures used
identify if they have a delay or disorder
identify specific targets for intervention
distinguish difference vs disorder
psychometric features of assessment
validity & reliability
diagnostic accuracy
validity
how well does the assessment measure what it says it measures
construct validity
underlying theory on which the test is based
does it measure what it says it measures
content validity
degree to which test items represent a defined domain
ex - receptive tests must be nonverbal
criterion related validity
degree to which the results of one test align w/ other tests
predictive validity
does a test score predict a student;s future performance results
reliability
to what degree is the test free from measurement error across forms, raters, time, & within an instrument
interrater reliability
will the results be the same regardless of examiner
test retest reliability
will the child have the same score on a different day
or is it too context dependent
