THE LOGIC OF INTELLIGENCE TESTING
THE CONSEQUENCES OF INTELLIGENCE TESTING -
intelligence along with other factors could influence a child 's performance
-
intelligence tests predict school performance (r=o 5) .

WHAT INTELLIGENCE TESTS OMIT
Sternberg suggests 3 kinds of
Intelligence :
→ Analytical : identify problems and find strategies for solving them
. Howard Gardner believes that standard intelligence tests fail to measure important human abilities
→ creative :
generate novel solutions
→ that few abilities measured standard tests because
argues only a are in
they are most valued
→ practical : apply and implement solutions to everyday settings
by Western culture but other cultures may conceive of intelligence differently
•
everyday intelligence requires tacit
knowledge
