Transcript of IQ Testing
rather identify students who were not on course in hopes to develop better ciriculum Intelligence Quotient (IQ) Index derived from standardized tests of intelligence Binet-Simon Intelligence Scales -Presented items in order of difficulty, and took into consideration the typical developmental abilities of children at various ages -Early tests were taken to Stanford University
-Renamed Stanford-Binet Test -Scores referred to as intelligence quotient (IQ) Created tests divided into two main areas: Verbal- Tested vocab, comprehension,
knowledge and general info Non verbal- Arranging pictures into stories
arranging blocks, ect. Scored differently than Binets IQ test Example: If a child of age 10 had a mental age of 12 (performed on the test at the level of an average 12-year-old), the child was assigned an IQ of 12/10 × 100, or 120 Average test scores 90-110
Below 70- indicates intellectual disability
130 or higher-Considered gifted
140-160- Highly advanced or very gifted
165 or higher- classified a genius Eugenics- refers to the goal of improving the genetic makeup of a population by reducing or eliminating allegedly inferior genes -coined term, grandson of Charles Darwin Sir Francis Galton: -believed that the principles of Darwinian evolution
could be applied to rid the population of what they felt were 'undesirable' human social characteristics Pros Cons http://www.indiana.edu/~intell/intelligenceTests.shtml http://www.learner.org/series/discoveringpsychology/16/e16glossary.html http://education-portal.com/academy/lesson/history-of-intelligence-testing.html Stanford-Binet IQ test Ages 2+ Measures general intelligence and four factors: verbal reasoning abstract/visual (spatial) reasoning short-term memory quantitative reasoning http://www1.assumption.edu/users/emhowe/220%20Presentations/Grp.%203%20Intelligence.htm David Wechsler “Intelligence is the aggregate or global capacity of the individual to act purposefully, to think rationally and to deal effectively with his environment." Psychologist 1896-1981 Wechsler Intelligence Scale for Children Used with children 6-11 Modern day Intelligence Scale yields a full-scale IQ score and four index scores: Verbal comprehension Perceptual Reasoning Processing Speed Working Memory IQ Tests Used Today Henry Goddard American psychologist wanted to limit the immigration of supposedly 'inferior people' into the U.S. tested immigrants at Ellis Island 1917, he reported that 'as many as 40-50% of immigrants were feebleminded Results- Tests favored Goddard's own culture
and language Problematic Modern day tests are similarly problematic Low scores among minority groups-inferior
intelligence rather than indication of unequal
social and economic opportunity Remember IQ should not be used to
label individuals but to facilitate our
understanding them Intelligence is not a single, unitary ability
but a composite of several functions Valuable information about cognitive strengths and weaknesses Most are divorced from theories of intelligence Wechsler Intelligence Scale The Wechsler Intelligence Scale for Children-Revised (WISC-R) The Wechsler Preschool and Primary Scale of Intelligence (WPPSI) The Wechsler Adult Intelligence Scale-Revised (WAIS-R) Only test what they are testing- don't taking into consideration: inspiration, motivation social abilities compared scores of the test-taker to those of others in his or her general age group compares scores of the test-taker to those of others in his or her general age group https://docs.google.com/viewer?a=v&q=cache:dLB-M3PCuTEJ:www.assess.nelson.com/pdf/sb5-asb1.pdf+stanford+binet+IQ+test&hl=en&gl=us&pid=bl&srcid=ADGEESjOO9kb4whMO66CD6UR8_ZIvs7U4eI8TUWQImw3i1K9mNmY0dZd9wow6yw66v4Ia4QhzJEfKjQLQ10y4LD_xKCvGYq4svK4CCMsyWNzHEzoih0f_wx5Jr1LVNVECiL_uGs7hsnj&sig=AHIEtbT-IahrIvhBA5s7sLQ6fFXvV3sXeg
