The…

In order to build a knowledge-based society and meet the needs of lifelong education, open learning opportunities are growing at exponential rates. While such growth is commendable, there appears to be a very strong demand for distance guidance services in open education programme selection. The purpose of this study was to develop the online…

This monograph critiques the many nonexperimental impact estimation approaches that have been based on external comparison groups. It proposes an approach to evaluating employment and training (E&T) programs that calls for using the group of individuals who apply to a program but then choose not to participate in that program as an…

A rationale is presented for the use of many cases in policy analysis. Case study families were selected from nomination by early intervention professionals in three states with differing early intervention policies and procedures. Using rating scales, demographic data, and interview transcripts with 72 families of children receiving services, 7…

A common theme in current school reform efforts is that teachers within schools must become reflective practitioners if they are to become more successful in improving instruction to meet the needs of increasingly diverse populations. In an effort to help schools promote district-level reflection about instructional improvement, Boston College's…

The contrasting groups method is one of many possible methods for setting passing scores. The most commonly used method is probably that developed by W. H. Angoff (1971), but it has been suggested that the Angoff method may not be appropriate for many standard setting applications in education. The contrasting groups method is explored as an…

This report provides an overview of a selection of measurement error studies conducted on National Center for Education Statistics (NCES) surveys.

The Texas Poll of Elementary School Teachers was a statewide telephone survey designed to accurately describe the current science teaching practices in Texas public elementary schools, and the extent to which these elementary teachers feel prepared for the task. This paper focused on the survey sampling procedures and questionnaire design used in…

Three methods for the estimation of the reliability of single dichotomous items are discussed. All methods are based on the assumptions of nondecreasing and nonintersecting item response functions and the Mokken model of double monotonicity. Based on analytical and Monte Carlo studies, it is concluded that one method is superior to the other two…

This manual has been produced to familiarize data users with the procedures followed for data collection and processing of the first follow-up component of the National Education Longitudinal Study of 1988 (NELS:88). A corollary objective is to provide the necessary documentation for use of the data file. Use of the data set does not require the…

The effectiveness of five methods used to estimate the population parameters of a variable of interest from a random sample in the presence of non-response to mail surveys was tested in conditions that vary the return rate and the relationship of the variable of interest to the likelihood of response. Data from 125,092 adult Alabama residents in…
