Current estimates of the contribution of education to economic growth have been questioned because they ignore the interaction of education with ability. Whether the neglect of ability differences in the analyses of the income-education relationship results in estimates which are too high is considered in this paper, using a 1964 sample of U.S.…

Research on sibling influence on intellectual ability has shown that academic ability and achievement decrease as family size increases and as spacing between siblings decreases. Research also suggests a relationship between sex of subject and of sibling, and age differences in the effects of birth order and sibling sex. (JAC)

In a study in which Asian-American, white, and black children in grades 2-6 in a California school district were given a battery of tests including measures of IQ, scholastic achievement, and short-term memory, factor analysis of the tests yielded two main factors identified as Level I (memory) and Level II (general intelligence) in Jensen's…

Until the 1970s, there were few signs of change in the historic difference of one standard deviation between average ability or achievement test scores of black and white students. From 1970 to the mid-to-late 1980s, there was a substantial convergence of the average achievement test scores of blacks and whites. From the mid-to-late 1980s to 1992,…

Models which describe assumptions concerning the distribution of intellectual capacity are: (1) the differential distribution model, encompassing theories that consider differences in intelligence genetic; (2) the normal distribution model; and (3) the evenly distributed model, focusing on the similarity of intellectual potentials within the human…

Several common assumptions about human intelligence are challenged in this paper. The "bucket" theory of intelligence describes intelligence as a stable psychological characteristic which affects learning, and which, when accurately measured, predicts an individual's learning capacity. The authors reject the idea that people who have…

The importance and consequences of raising the average ability level (IQ) of the population requires consideration of the ability level that society requires, how the relevant abilities are distributed, and the efficiency of the current educational process. Within the framework of these factors, the document discusses the determinants of mental…

The purpose of this paper is to present some preliminary findings on the effects of racial status, socioeconomic status (SES), and measured ability (MA) upon academic performance of students in a liberal arts college. Preliminary analyses of academic performance (cumulative grade point averages and semester-by-semester grade point averages) among…

Three themes have dominated the sociology of education: the sub-cultural thesis, the socio-cultural advantage thesis, and the biogenetic thesis. With regards to the last, one should try to account for differences in the behavior of identifiable social groups by looking for social causes. The relationship between the strength of the bonds attaching…

Explores the application of Howard Gardner's theory of Multiple Intelligences (MI) in developing a community college curriculum that enhances an educator's ability to teach students based upon their dominant intelligences, such as verbal/linguistic or musical/rhythmic. (VWC)
