Although a lot of data on the psychological characteristics of children having learning disabilities have been gathered, not very much has been done to discover the underlying mechanisms, processes, or phenomenon of learning disability. Without more investigations which attempt to get at these, we will continue to be at a loss to prescribe…

Social scientists with an interest in education policy have devoted a great deal of time in recent years to assessing if the level of per pupil school expenditures is related to any outputs of formal education that are valued by our society. In this paper we develop several alternative models for the purpose of estimating the effects of per pupil…

A method for modeling the structure of large social systems has been developed which is based on the interpersonal communication networks present in the functioning system. Recent developments in techniques and computer software have made possible the analysis of networks of several thousand persons. The new technique provides a method for…

A companion piece of volume 1, this section of the feasibility study consists entirely of eight appendixes. Appendix A describes the objectives of the study and how they were operationalized. Appendix B consists of the information kit used to inform community members about the education voucher program and includes clippings of newspaper articles…

This paper is an empirical statistical analysis and interpretation of data relating to school readiness previously examined and reported on a theoretical basis. A total of 118 white, middle class children from six consecutive kindergarten groups in Dearborn, Michigan were tested with seven instruments, evaluated in terms of achievement, ability,…

The purposes of the project reported here were (1) to explore and describe the formal and informal relationships among black and white students in a large, racially mixed, urban high school, and (2) to attempt to explain how those relationships affect student behavior, administrator and teacher behavior, and other facets of the school…

This study was designed to test the effects of positive teacher expectancy instructions, positive student expectancy instructions, and positive performance feedback on the academic performance of second, third, and fourth grade students. 13 teachers (5 fourth grade, 4 third grade, and 4 second grade) from a rural Texas elementary school nominated…

In this research on individual differences in thought processes, the primary interest was to study the process followed by the subject in order to reach the solution of the problem. For this purpose, the performance of 38 experimental subjects was studied throughout 24 problems of the training sessions. The methods used were group norms, length of…

The current state of disarray in mass communication research can be cleared up by the orderly application of more careful media research procedures. Semiotics and structural analysis promise some advances in media studies, but these methods are limited when applied to peculiar qualities of time in film and television. A more fruitful approach…

An overview of relevant literature reveals that residents in urban areas apparently have a multitude of nonoccupational information needs which are not being satisfied within the constraints of existing information resources and systems. A conceptual framework was drawn, focusing on four basic components--urban residents, their needs, sources of…

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…

In this paper some general findings from educational surveys in science, reading comprehension, and literature are reported. A brief description of the research methodology is given. Science was tested in 19 countries, reading in 15 countries and literature in 10 countries. The target populations in each country are defined. Outcome measures in…

Hypothesizing that the dimensions of developmental problems faced by the moderately retarded will be analogous to those faced by the mildly retarded, this study considers the appropriateness of the structure of the Social Learning Curriculum (SLC), originally developed for the mildly retarded, for the moderately retarded. The SLC framework…

This book on the genetic and environmental influences on intelligence is comprised of the following papers: "The Structure of Intelligence in Relation to the Nature-Nurture Controversy," R. B.

An estimated 36 million Americans--or 19 percent of the population--lived in racially integrated neighborhoods in the spring of 1967. Yet, the number of Negroes living in such neighborhoods tended to be small in comparison with the number of whites. The research operations for this study, which began in the autumn of 1966, were divided into three…
