The major goal of this research was the development and validation of cultural models of dental health practices. The specific objectives were to determine if 3 cultural groups (American Indians, Mexican Americans, and Anglo Americans) differ in the dental health hygiene indices, characteristics, psychological factors, or social factors; to…

The purpose of this study was to provide knowledge not previously available to professional educators concerning the paraprofessionals in Oregon secondary schools. The study was concerned with an analysis of differentials in paraprofessional role expectations as they occur among and between administrators, teachers, and paraprofessionals. An…

This analytical study of teacher migration in Michigan was conducted in an effort to understand better the complexities of the problem of teacher supply and demand. The major purposes of the study were to (1) generate a research design and an index capable of the analysis of substantial data about the turnover behavior of teachers; (2) acquire…

This study has been undertaken to assess the magnitude of the school bus safety problem and to develop a plan to improve pupil transportation safety. The resulting report provides estimates of school bus population and daily usage, gives an account of injuries and fatalities that occur annually, and compares the safety records of school buses to…

A program of planned intervention to facilitate language growth in kindergarten children at Cheyenne Eagle Butte was conducted during the 1970-71 school year. The study sample consisted of the students in 2 kindergarten classes, one considered low and one considered high, as judged by family economic background, Headstart experience, and…

This is one of a series of reports on the National Longitudinal Study of Mathematical Abilities (NLSMA). Further, it is of the subseries that reports the data analyses for the possible correlates of mathematics achievement; this particular report contains the correlates classified as attitude and role variables for students in grades 4 through 12.…

The paper discusses various models and theories of personal income distribution inequality. The first section presents the logic for adopting one conceptual and statistical approach in measuring and analyzing income inequality and the second presents empirical evidence on income inequality from 1939 to 1970. A brief survey of the human capital…

This is the third in a series of three tests of selected micro-teaching and video recording feedback techniques in laboratory settings designed to stimulate vocational teacher education programs. A comparison was made of the relative effectiveness of: (1) face-to-face supervision with video feedback, (2) remote supervision via video feedback which…

This report describes the fifth in a series of studies assessing micro-teaching and video recording in vocational and technical education. The 48 participants were randomly assigned to eight treatment groups which consisted of combinations of the two levels of the three major variables: (1) video feedback or no feedback, (2) teaching four 5-minute…

This review is one in a series intended to develop methods which maximize the use of the existing scientific literature as a basis for predicting human performance. It is concerned with sensory performance in target detection, defined in terms of the "probability of detection" of a flash of light. Two conditions of detection are…

This study was designed to investigate the effectiveness of low cost instructional simulation, with numerical control (N/C) used as the subject vehicle. A unit of study was developed that included a detailed list of the behavioral changes which were desired for the students and the instructional materials and procedures deemed necessary for aiding…

This study describes the total speech communication coursework required within New York State secondary level teacher programs in 1968-69 with a focus on three questions: (1) What speech-communication coursework is required within secondary level teacher preparation programs; (2) What discussion leadership principles are required; and (3) Does the…

This guide presents many new experimental designs for data analysis and reviews certain standard procedures. It is hoped that the treatment of the material will stimulate new applications since the emphasis of the guide is on the problems encountered in running experiments rather than on an elaboration of mathematical models. Discussed are:…

This study attempts to determine whether the Piers-Harris Self-Concept Scale is appropriate for use with varying population types, and whether the dimensions identified by it are sufficiently consistent across samples to allow some clarification of the nature of self-concept in children. (AE)

A reliable instrument was developed to assess the value orientations of individuals toward four basic epistemological dimensions concerning the perceived nature of knowledge, the learner and learning activity, and the purpose of schooling. Earlier research has shown these four dimensions discriminate between curriculum materials and instructional…
