Module 2.8 Flashcards
Intelligence and Achievement
g
general ability
Intelligence quotient (IQ)
the IQ was calculated by dividing the mental age by the chronological age
Standardized
a test is standardized when it is administered using consistent procedures and environments
Valid
a test is considered valid if it measures what it is designed to measure
construct validity
the degree to which a test or instrument is capable of measuring a concept, trait, or other theoretical entity
predictive validity
evidence that a test score or other measurement correlates with a variable that can only be assessed at some point after the test has been administered or the measurement made
Reliable
yields similar results each time it is administered
test-retest
is a way of assessing the external reliability of a research tool. It involves presenting the same participants with the same test or questionnaire on two separate occasions, and seeing whether there is a positive correlation between the two.
split half
a test for a single knowledge area is split into two parts and then both parts given to one group of students at the same time. The scores from both parts of the test are correlated. A reliable test will have high correlation, indicating that a student would perform equally well (or as poorly) on both halves of the test
Socio-culturally responsive
researchers strive to develop assessments of intelligence tests that are responsive to social and cultural factors; this will help to reduce stereotype threat and other inequities
Flynn effect
IQ scores across much of the world have generally increased over time; this may be due to societal factors like better nutrition
Achievement tests
attempt to measure what someone knows
Aptitude tests
attempt to predict how someone will perform in the future
Fixed mindset
people’s belief that intelligence is fixed from birth
Growth mindset
people’s belief that intelligence is malleable due to experience
