1 Origins & Modern Intelligence Tests Section EKathy Lew, Eric Lee,Andy An, Taehun Choi
2 which children need assistance! OriginWe need a way to assesswhich children need assistance!
3 Alfred BinetThrough the questions, Binet and Simon was able to analyze that some children were able to answer harder questions that are usually solved by older children…And the other way around, too.
4 Binet-Simon ScaleBinet and Theodore Simon created an intelligence test.Series of questions required:- Attention- Memory- Problem-solving skills
5 Binet-Simon Scale However, Still a basis for the intelligence testes used todayHowever,Binet thought there arelimitations on this test
6 too broad to be identified with The problem is:Intelligence istoo broad to be identified witha single number!It is influenced by factors such asChanges over time
7 Stanford-Binet Intelligence Test Binet-Simon scale was introduced to United StatesLewis Terman took the original test and standardized in U.S., introducing it to the public in 1916.
8 Stanford-Binet Intelligence Test The test used intelligence quotient (or IQ)(Mental Age/Chronological Age) X 100Ex) A child with MA of 15 and a CA of 11 would have an IQ of 136 (15/10 X 100)
14 Modern Tests of Mental Abilities Aptitude TestsA test designed to predict a person’s future performanceCapacity to learnAchievement TestA test designed to assess what a person has learnedEx) AP Psychology
15 Wechsler Intelligence Scales Developed by David WechslerDeveloped 2 ways for childrenWechsler Intelligence Scale for Children (WISC)Wechsler Preschool and Primary Scale of Intelligence (WPPSI)And a version for adultsWechsler Adult Intelligence Scale Fourth Edition (WAIS-IV)
16 WAIS Measures one’s overall intelligence and 11 other aspects related Analyze one’s educational problem.4 major aspects:Verbal Comprehension IndexPerceptual Reasoning IndexWorking Memory IndexProcessing Speed Index
17 Wechsler Intelligence Scales Scored by comparing one’s score to that of others in the same age groupVS
18 Modern WAIS test (2008 Edition) have 15 subtests
19 Constructive Intelligence Test Should be …. ReliableValidStandardized
20 Standardization Uniform testing procedures Meaningful scores by Comparison with performance of a pretested group.Consistency and objectivity of how tests are administered and scored.
21 Normal Curve= Symmetrical bell-shaped curve that describes the distribution of many physical and psychological attributes
23 Reliability The consistency of a test or a measure Ex) If a subject were to take an intelligence test, then the consequent results should all be the same or at least approximately the same.
24 Validity Content Validity → How well a test samples the behavior that is of interest.Ex) If Mr.Mussleman were to give a quiz on intelligence test and if the quiz does in fact measures one’s knowledge of intelligence test, then the quiz can be said to have content validity
25 Validity Predictive Validity → The success with which a test predicts the behavior it is designed to predict.Ex) College Entrance Test (SAT, ACT)
