Methods for selecting relevant and appropriate quasi-experimental studies for inclusion in research synthesis using the threats-to-validity approach are presented. Effects of including and excluding studies are evaluated. (BS)

This study examines the relationship between high-stakes school accountability and its effects upon student test scores and school policies. The authors seek to understand the extent to which accountability sanctions and incentives for the poorest-performing schools in Florida explain subsequent changes in school practices and policies as well as…

This is one in a series of technical reports presenting summary statistics derived from the University of Washington registrar's office quarterly scholarship lists. Two types of tables are included: first, for each class, the mean cumulative grade-point average, standard deviation, and number of students enrolled in autum, winter, and spring…

It has been proposed that the Objective Measure of Ego Identity Status and its scoring criteria should be adjusted to utilize a half standard deviation cutoff. Evidence is provided to support the claim that less stringent criteria will lead to higher numbers classified while arriving at the same research results. This proposal is considered and,…

Despite statewide standards, the accuracy of statistical data on dropouts reported by New Jersey schools appears to vary considerably from district to district. Moreover, statewide dropout rates differ significantly depending on the method of calculation used. Several different methodologies, which incorporate unverified information collected from…

Methods for meta-analysis have evolved dramatically since Gene Glass first proposed the term in 1976. Since that time statistical and nonstatistical aspects of methodology for meta-analysis have been developing at a steady pace. This guide is an attempt to provide a practical introduction to rigorous procedures in the meta-analysis of social…

This study presents a scheme for yearly, comparative, computation of state and local government tax capacity and effort. Figures for all states for fiscal year 1975 are presented in extensive tables. The system used is a simplified version of the Representative Tax System, which identifies tax bases, determines national average tax rates for those…

The study was made to obtain curriculum development data for food service education programs below the baccalaureate level. Tasks related to the job functions of service, production, sanitation/safety, menu planning, procurement, supervision, and management were studied for five job categories of full-time personnel: middle-level service,…

The five point scale is the most frequently applied scaling used in the current practices for evaluating instructor classroom performance through graduate student observations. Hence, the investigation addressed itself toward determining, through a series of 55 computerized exact randomization tests, at what degree of mean differences would…

In the study reported, the labor force characteristics of the nation's 16.2 million teen-agers (aged 16 to 19) are reviewed and evaluated for three types of area: central cities, suburban rings, and nonmetropolitan areas. Tables give data on teen-age employment and unemployment, comparing sex, race, and occupational groups. (Author/AJ)

This paper examines interaction in a school class through the factor-analytical P-technique, considers the behavior of the factor scores in combination with certain other variables included in the interaction matrix, explores the formation of homogeneous groups of lessons in a grouping analysis based on the factor scores, and compares this latter…

Quantitative growth curve models for estimating individual developmental functions from various types of longitudinal data are discussed in the context of investigator assumptions and research design characteristics. Linear and nonlinear models that estimate growth curves are illustrated, and contrasted when they are fit to speech development…
