The growth model of intelligence; i.e. intelligence is the product of genetics plus environment (I.Q.=G+E), is discussed and questioned. If the growth model is discarded, formulating the problem of the development of intelligence in different ways and thinking of different possible technologies for changing intelligence can begin. The child…

This final study in a series reports the investigation in detail of the sex-related differences in the mathematics achievement of sixth grade students. Students were stratified in four intelligence levels with 91.5, 101.5, and 111.5 IQ as cutpoints. Twenty computation scores and eight contemporary mathematics scores were derived from the…

Researchers have concluded that the continued debate over the heredity-environment issue concerning the nature of intelligence is nonproductive. Recent evidence demonstrates that intellectual abilities can be improved with practice. Heredity may determine upper limits of abilities within individuals, but there is considerable room left for…

We should seek an updated perspective on intelligence testing because it is useful to reevaluate any practice that has long become institutionalized, especially one that is subject to severe criticism. Cultural bias is the most prominent criticism. Testing proponents contend that intelligence tests reflect skills and knowledge emphasized in school…

Currently, the reliance on intelligence tests as the primary criterion for the placement of children in school programs has been challenged. Much of the controversy focuses on the insensitivity of these instruments to individual cognitive styles for different subgroups of children. While the issue of whether intelligence tests measure skill…

THE AVERAGE IQ SCORES OF DIFFERENT STUDENT GROUPS WERE COMPARED--HIGH SCHOOL FRESHMEN ENROLLED IN VOCATIONAL AGRICULTURE AND THOSE NOT ENROLLED, AGRICULTURE I AND AGRICULTURE II STUDENTS, AND RURAL AND NONRURAL STUDENTS. DATA WERE COLLECTED FROM 18 OF 24 RANDOMLY SELECTED HIGH SCHOOLS WITH A FOUR-SECTION QUESTIONNAIRE ADMINISTERED BY THE…

IN ORDER TO DEVELOP AN INTELLIGENCE TEST FOR PRESCHOOL-AGE CHILDREN THAT WOULD OVERCOME SOME OF THE LIMITATIONS OF AVAILABLE TESTS, A PERCEPTUAL DISCRIMINATION TEST USING POLYGONAL FORMS HAS BEEN DESIGNED AND TESTED. THE CHILD POINTS TO ONE OF TWO, THREE, OR FIVE FORMS MATCHING A STIMULUS FORM. INITIAL TESTING WITH 44 CHILDREN RANGING IN AGE FROM…

The application of Piaget's theory of cognitive development to the assessment of mental ability of the mentally retarded is presented. Following a discussion of developmental theories and diagnosis of mental development, testing interviews demonstrate the limits of cognitive thought at each of three stages. Abnormal intellectual oscillations are…

Different viewpoints regarding educational testing are described. While some people advocate continuing reliance upon standardized tests, others favor the discontinuation of such achievement and intelligence tests. The author recommends a moderate view somewhere between these two extremes. Problems associated with standardized testing in the…

A total of 23 children were observed from age 1 to 3 in order to assess day-to-day learning environments and their effect on intellectual development. Observers used a time-sampling technique to code behaviors for one hour on three to five separate occasions during each of four periods: age 12-15 months, 18-21 months, 24-27 months and 30-33…

Every human being is always open to some degree; for example, open for learning, experience, change, improvement, or further degradation by his own standards or those of others. Every experience alters an individual's learning capacity. Therefore, to say a child is naturally of high or low intelligence with unlimited or limited learning power is…

To measure school achievements in spina bifida children, to relate these measures to certain variables, to obtain information on educational problems, and to study facets of cognition and its changes with age, 77 spina bifida children and 53 amputees (all aged 5 to 15) were tested. Sixty non-disabled children were at times used for controls. The…

A within cultural comparative examination of three samples of school-children residing in Saskatchewan, South Australia and Nova Scotia enabled the effects of family size and socioeconomic status on measured intelligence to be ascertained. Samples of schoolchildren in Regina (Canada), Adelaide (Australia) and Sydney (Canada), divided into…

This report presents national estimates of the intellectual development levels of noninstitutionalized children 6-11 years of age in the United States. These estimates were determined by scores on the Vocabulary and Block Design subtest of the WISC obtained in the Health Examination Survey of 1963-65. Findings are shown by age, sex, and grade in…

The inadequacy and misuse of intelligence testing for minority group children are examined. IQ test items, norms, examining procedures, and language usage are discussed in terms of their bias against minority children. The implications of this bias for the classroom teacher are explored with the view that teacher mental sets are powerful mediators…
