The study tests hypotheses derived from the proposition that open education promotes self-concept. The Sear's Self-Concept Inventory, yielding scores in six self-concept "areas," was administered to 316 students, ages 9 to 12, from six suburban schools. The Walberg-Thomas Scales rated each school as to degree of openness. No significant…

This study was designed to determine if the hours during which students participated in electronics training had any influence on their learning efficiency and their ability to function effectively as students, and to identify those factors that contributed to diminished learning efficiency. The three shifts used for the experiment were the night…

This document consists of unrevised lecture notes for the first half of a 20-week in-house graduate course at Rand Corporation. The chapter headings are: (1) Histograms and descriptive statistics; (2) Measures of dispersion, distance and goodness of fit; (3) Using JOSS for data analysis; (4) Binomial distribution and normal approximation; (5)…

The accounting department at the University of Arizona, faced with numerous sections of introductory accounting, full classrooms, testing periods spread over two days, and a shortage of clerical help, evolved this testing program for the course in introductory accounting. Two objective multiple choice tests are constructed which sample different…

This study's aim was to explore the relationship of acquiescence, social desirability (SD), and defensiveness response styles with first, second, and any higher order factors on the 16 PF. All the various kinds of response bias indexes were appreciably correlated with the first order factor scales. Each kind of response style measure predominantly…

In a previous Semantic Differential study, Ayrer and Farber (1972) reported the results of a factor analysis which utilized a matrix sampling approach. Some problems were encountered (negative eigen-values). The current study did not involve matrix sampling, but the same basic results were obtained. This suggests matrix sampling may be an…

The problem of comparing proportions when some data are missing is investigated, and determination is made of what statistical techniques are appropriate under each of several probability models describing the observations likely to be missing. Monte Carlo methods were used to investigate the properties of standard estimators under each of the…

A method for estimating power scores is described. By way of illustration, it is applied to 21 students who were improperly timed on a standard test. Some empirical results are given in support of the estimation procedure. (Author)

Recent years have seen many attempts to program learning based on many principles ranging from intuition to mathematics. The area of criterion establishment for advancement or conversely additional training at the same or lower levels remains primarily in the realm of intuition. The intuition used is only as good as the experience and background…

This book is designated for an audience of the practitioners of education, especially those located in elementary schools. It is designed to investigate and explain research methods, terms, and concepts so that the reader can narrow down the many ways things are known or said to be known. Included in this book are chapters on the research process…

The testing of every fourth-grade classroom in Massachusetts was carried out in an effort to answer the following questions: (1) What are the levels of mastery of basic skills in Massachusetts fourth grades? Are there differences in achievement between skills?; (2) What educational needs can be inferred for Massachusetts' students, based on basic…

This study examines a common set of equating items for their appropriateness to both American and Canadian populations and, to determine the equations for converting scores from the verbal and mathematical scales of the 1971 form of the Canadian Scholastic Aptitude Test (the future standard continuing scales of the CSAT) to the corresponding…

Teachers and assistant teachers (N = 32) from two rural counties in North Carolina rated five pre-school educational settings and one hypothesized ideal setting using a semantic differential in order to determine if the semantic differential could be used to reliably differentiate between pre-school educational environments. Five discrepancy…

The purpose of this study was to determine if measures of first grade readiness, scholastic aptitude, and reading achievement were significant predictors of third grade reading achievement for Mexican-American students from two lower socioeconomic levels. The sample included 94 third grade students for whom the following measurements had been…

A study was conducted in rural Maryland which utilized a 3-stage panel design with experimental and matched control groups. The questions to which answers were sought were: (1) What specific changes are achieved over time by nutrition aides visiting rural poor mothers in their homes? (2) Is there a point of diminishing returns with home visits?…
