This study examined the effects of family size on a sample of some 5000 students in Bayamon, Puerto Rico and examined the effects of family size and spacing on some 537 families in four suburban towns near Boston. It was found that there were major effects of both socio-economic status and religion on family size, but that the direction of the…

This paper repudiates Jensen's hypothesis that differences in IQ scores and scholastic achievement in Negro and white children are genetically based. Specifically, Jensen's identification of IQ scores as a measure of abstract reasoning and problem solving and of levels of ability, and his evaluation of the magnitude of the genetic component in IQ…

This is an extensive study of Ann Arbor's first school desegregation effort, involving the 1965 closing of Jones elementary school and subsequent reassignment of its predominantly Negro population to predominantly white schools. The research focused on the first year of school desegregation, exploring academic, social, behavioral, and attitudinal…

The Anchor Test Study provides a method for translating a pupil's score on any one of eight widely used standardized reading tests for Grades 4, 5, and 6 to a corresponding score of any of the other seven tests, as well as furnishing new nationally representative norms for each of the eight tests. In addition, the Study presents new estimates of…

The concern of this investigation lies with the development and estimation of models explaining children's intellectual variability. Specifically, attention is directed to: (a) the role of parental status attainments and family environments in the transmission of intellectual advantage-disadvantage across generations; (b) the possibility that…

The major interest of this study is the amount of time children spend reading. Data was gathered unobtrusively by having the 150 5th grade subjects keep time records of all their activities for a 2 week period. These were coded into 7 categories and scores were related to those derived from tests of ability, achievement, self-concept and reading…

The study sought to: (1) ascertain the attitudes of educators, students, and parents in slum, suburban, and cross-sectional areas, toward blue-collar occupations and vocational education, (2) identify significant differences between attitudes of groups with union and non-union backgrounds, and (3) identify any existing relationship between general…

The controversy over intelligence testing is more often influenced by political considerations than empirical research. A survey of 1,020 experts found that a majority agree that (1) intelligence can be defined; (2) heredity plays a role in individual and group IQ differences; and (3) intelligence testing in schools should continue at its present…

Students of high intellectual ability and their parents were tested on a battery of cognitive tests. Vernon's model of intelligence best fit results. A verbal-educational and a practical-spatial-mechanical factor explained most performance variance. Among children, age related to verbal but not spatial or mechanical abilities. (Author/RD)
