This article addresses the problem of estimating the proportion Pi[subscript S] of the population belonging to a sensitive group using optional randomized response technique in stratified sampling based on Mangat model that has proportional and Neyman allocation and larger gain in efficiency. Numerically, it is found that the suggested model is…

Using a computer-based Monte Carlo approach to generate item responses, the results of this study indicate that, when item discrimination indices are considered, item-examinee sampling procedures having the same number of observations have different standard errors in estimating both test mean and test variance. With certain types of tests, a…

The purpose of this study was to help determine optimum item sampling plans for use in school evaluation projects. (Author)

The second section of a four-part technical report of Florida's statewide program for assessing reading-related skills in grades 2 and 4 provides statistical and scoring information. Item and student sampling, a test re-scoring study, reporting statewide assessment data (percentage of achievement, types of tables used), and standard error…

This report documents a methodological study conducted for the National Science Foundation to investigate the effects of different media environments on relationships between local television news viewing and local knowledge. The study serves two purposes: it establishes tne reliability of data collected in an investigation by Rand of the effects…

This report summarizes tasks undertaken to assess the feasibility of a longitudinal analysis of elementary and secondary schools. The initial objective was to see if it was technically possible to analyze overlap samples of schools from the Schools and Staffing Survey (SASS) to produce substantive findings. Over the course of the project various…

The research reported includes a profile of all sixty ThinkAbout programs with respect to demographic balance, personal/social behaviors portrayed by major characters, and value-laden content. The profile is a summation across a 5-stage content analysis which was integrated with other formative evaluation techniques in the three year ThinkAbout…

Two studies investigated upper elementary school students' informal understanding of sampling issues in the context of interpreting and evaluating survey results. The specific focus was on the children's evaluation of sampling methods and means of drawing conclusions from multiple surveys. In Study 1, 17 children were individually interviewed to…

The development of content analysis instruments sensitive to the instructional, social, and value-laden content of a television series, was necessary because of formative evaluation needs to establish the congruity of the actual program content with the intended content and to assess the hidden curriculum. Because issues ranged widely, four…

The Quality Circle project is a problem-solving concept requiring the interaction of a variety of organizational skills. Circle members work together, becoming involved in problem-solving processes. They make decisions and take action based upon the data they collect. The reliablity of those data is crucial to the circle's success. Presented in…

The Schools and Staffing Survey (SASS) is a periodic, integrated system of sample surveys on elementary and secondary schools in the United States that collects information on school and district administrators and teachers in public and private schools. This technical report is one in a series of methodological studies relating to the SASS of the…

A 1994 report, "Quality Profile for SASS, Aspects of the Quality of Data in the Schools and Staffing Surveys (SASS)," presented and summarized the available information about the quality of the data from the five surveys that made up the SASS in its first two rounds of data collection (1987-1988 and 1990-1991). This report updates the…

The purpose of this study was to empirically determine the effects of quantified violations of the underlying assumptions of parametric statistical tests commonly used in educational research, namely the correlation coefficient (r) and the t test. The effects of heterogeneity of variance, nonnormality, and nonlinear transformations of scales were…

Presents listening comprehension strategies used by students learning French. Through interviews, students described their conscious use of strategies in different contexts. All evidenced a familiarity with metacognitive, cognitive, and socioaffective techniques. (50 references) (Author/CK)

This interim report of a pilot year impact study on evaluation methodology is part of a series of documents on the evaluation of Project Developmental Continuity, a Head Start demonstration program aimed at promoting educational and developmental continuity between children's Head Start and primary school experiences.
