Assessment Final Flashcards
Content Validity Bias
an item/test is more difficult for one group than others when general ability level is held constant
Construct Validity Bias
is the test measuring the same hypothetical traits/construct
-use factor analysis
Predictive Validity Bias
is a test related to a criterion (e.g., achievement)
-also called slope bias
Conceptualizations of Test Bias
Egalitarian definition
group difference in test scores indicates a test bias?
doesn’t mean the test itself is biased
Conceptualizations of Test Bias
Standardization definition
test is biased against the groups omitted from the standardization sample?
Conceptualizations of Test Bias
Culture-Bound definition
“culture-loaded items” are biased against certain groups?
general and culture knowledge; heavily loaded verbally
Statistical perspective of test bias
test bias refers to systematic error in the estimation of some “true” value for a group of individuals
Implications for Assessment of CLD Children
- assess a child’s level of acculturation
- assess home language and development in English
- use multiple sources of information
Non-verbal assessment
- low in linguistic demands
- is nonverbal assessment “culturally fair or culture free?”
- testing is itself a “cultural activity”; all tests have some degree of cultural loading
Dynamic Assessment
assess the degree to which children improve with feedback
Ecological Assessment
assess the quality of school and community support in terms of language and learning
-do they have skills that might be adaptive for their culture or origin?
Bilingual Assessment
Assessment of bilinguals by bilingual school psychologists
Acculturation
cultural, psychological changes that results from contact with culturally dissimilar groups
Culture-Language Interpretive Matrices
attempt to tease apart if test scores are systematically affected by cultural loading and linguistic demands
-thus far, empirical support for this approach is lacking
Culture-Language Test Classifications (C-LTC):
WISC
Matrix Reasoning (low,low) Block Design (mod,low) Symbol Search (mod,low) Digit Span (mod,low) Coding (mod,low) Letter-Number Sequencing (high,low) Similarities (high,high) Vocabulary (high,high)
