We conducted a systematic literature review examining the participant characteristics of studies of students with emotional disturbance (ED) with the purpose of better understanding potential similarities and differences between students with ED in research and the population of students with ED. Results indicate (a) participants with reported…

Autism research tends to exclude racially and ethnically minoritized autistic individuals, limiting the quality of the evidence base for characterizing and diagnosing language impairment in racially and ethnically minoritized autistic individuals. This systematic review examines reporting practices for participant socio-demographics in studies…

This is the first of two reports that summarize the findings from an impact evaluation of a violence prevention intervention for middle schools. This report discusses findings after 1 year of implementation. A forthcoming report will discuss the findings after 2 years and 3 years of implementation. In 2004, the U.S. Department of Education (ED)…

One purpose of educational research is to provide information about the likely impact of interventions or treatments on policy-relevant populations of students. Randomized experiments are useful for estimating the causal effects of interventions on the students in schools that participate in the experiments. Unfortunately, the samples of schools…

Background: The Thinking Styles Inventory--developed by Sternberg and Wagner based on Sternberg's (1988, 1997) earlier theory of mental self-government--was selected for the research in order to assess thinking styles of student teachers. Another reason is that the theoretical constructs, as well as the inventory generated from the theory, have…

The literature and typical approaches to reducing attrition among college students are critiqued, and a strategy for the identification of different interventions likely to have positive effects on retention rates of different student subgroups is proposed. It is claimed that a small sample approach to empirical testing of the combinations of…

This manual provides guidance and documentation for users of the public release data for the student component of the National Education Longitudinal Study of 1988 (NELS:88). The general aim of NELS, a continuing long-term project, is to study the educational, vocational, and personal development of students at various grades and the factors that…

The Rasch model was used to equate reading comprehension tests of widely different difficulty for three groups of fifth grade students of widely different ability. Under these extreme circumstances, the Rasch model equating was unsatisfactory. (Author/CTM)

A stratified two-stage cluster sample design was chosen for the Texas Assessment Project and is described in this document. The sample was designed so as to achieve a chosen level of precision in item analysis data within each of the 20 geographic regions chosen for analysis. Four sampling frames were developed: 9-year-olds; sixth graders;…

This manual familiarizes data users with the procedures followed for data collection and processing of the second follow-up student component of the National Education Longitudinal Study of 1988 (NELS:88), with the corollary objective of providing necessary documentation for use of the data file. Chapter 1 presents an overview and history of the…

This manual familiarizes data users with the procedures followed for data collection and processing of the second follow-up dropout component of the National Education Longitudinal Study of 1988 (NELS:88), a survey of the educational and personal characteristics of students. The dropout data file contains records for 2,028 sample members who…

The 1980 National Center for Education Statistics' National Longitudinal Survey, "High School and Beyond," was intended to be a general, multi-purpose study, serving a number of diverse needs. The present study sought to increase the data's usefulness, accuracy, and scope. While allowing for analyses of schools and students on a national…

This technical report provides the results of a study on the calculation and use of generalized variance functions (GVFs) and design effects for the 1990-91 Schools and Staffing Survey (SASS). The SASS is a periodic integrated system of sample surveys conducted by the National Center for Education Statistics (NCES) that produces sampling variances…

Technical notes concerning the Survey of Income and Education (SIE), April-July 1976, which was conducted by the Bureau of the Census for the Department of Health, Education, and Welfare, are presented. Information is presented on the source of the data, sample design, estimation procedure, reliability of the estimates, nonsampling variability,…

This technical report presents results of an analysis of unit response rates for the components of the 1993-94 Schools and Staffing Surveys (SASS). The study was motivated by the general need to evaluate and improve the quality of SASS data and to identify potential sources of nonsampling error associated with nonresponse in SASS. As background,…
