This article examines statistical issues raised when standard methods are used to analyze educable placement data to determine possible racial discrimination. An alternate approach is offered that detects disparities while avoiding the pitfalls of present methodologies. (BS)

Recruiting schools and kids to participate in drug prevention evaluations is no longer, if it ever was, a "done deal." Since the mid-1980s, schools have been inundated with requirements for drug programs and requests to cooperate with program evaluations. As a consequence, both treatment and control schools are harder to find. In addition, many…

To determine the factors that influence interpretation of a research study description, 8 descriptions of research studies were interpreted by 320 undergraduate students in psychology, mathematics, and economics statistics and research methods classes at the University of Victoria (British Columbia, Canada), Millersville University (Pennsylvania),…

This study reexamines results reported by Angoff and Schrader regarding formula directions and rights directions for standardized tests. In that study, it was concluded that the two scoring directions were essentially equivalent. In this study, methodological concerns are discussed and additional data analyses undertaken. Among various…

As in any very large survey, the sample that provided data for the National Longitudinal Study of the High School Class of 1972 (NLS) differed from the random sample of the study design because of nonresponse from 226 of the 1,200 schools in the primary sample, and a small amount of other missing data. Part A of this report, briefly describes the…

A search, primarily by telephone, in 1974 successfully located 97.4 percent of a sample of 10,317 subjects who had graduated from Wisconsin high schools in 1957. This high response rate was obtained partly because the original study incorporated several diverse types of identifying items which could lead to the future location of the respondents;…

The National Education Longitudinal Study of 1988 (NELS:88) serves as an example of how three specific problems of representativeness in a longitudinal study may be approached and overcome. NELS:88 was designed to provide longitudinal data about the educational transitions experienced by students as they leave eighth grade and move through high…

Approaches to studying the relationships between stress and school organizational sources of stress were examined. Rather than sampling a number of schools and school average data indicating school health and stress levels in these schools, simple teacher samples and teacher-level analyses were used. For a sample of 1300 high school teachers in…

This publication is primarily designed for educational practitioners who possess little or no training in conducting mail surveys or have not kept current on the present state of the art of survey methods and techniques. It is also intended to be a checking and comparing aid to ensure that important research considerations are taken into account.…

Written to assist future researchers in conducting cross-national studies of classroom behaviors, this study indicates a number of factors which may reduce the validity of comparisons made. It is based on an investigation which explored the feasibility of using the Activities Categories Instrument and the Flanders Interaction Analysis Categories…

Chapter 1 of this report and user's manual describes design and implementation of the 1992 National Adult Literacy Survey (NALS). Chapter 2 reviews stages of sampling for national and state survey components; presents weighted and unweighted response rates for the household component; and describes non-incentive and prison sample designs. Chapter…

Longitudinal studies conducted with children typically experience non-response problems that can make substantial inroads on sample size and introduce bias into the analysis. Three methods for limiting non-response in school-based research programs were assessed: (1) asking parents to return consent forms only if they do not want their children to…

The utility of a quasi-experimental evaluation design for estimating benefits derived from a program to match job-seekers to openings listed by employers was examined in three studies of Job Service referrals and placements in Washington and Oregon. Data examined included a mail survey of a sample of 587 Washington residents referred to job…

A study conducted at one large research university compared electronic mail and telephones as methods for gathering survey data from undergraduate students. Problems associated with electronic-mail use include higher rate of socially undesirable activity among respondents and difficulty in identifying the target population. Implications for campus…

Research efforts have established that the Mantel-Haenszel procedure (MHP) is an effective method for detecting the presence of test items exhibiting differential item functioning (DIF). While the MHP has been advocated for situations where item response theory based methods may not be usable, recent findings have suggested that the performance of…
