This report presents the results of a working meeting to provide guidance to staff at the National Center for Education Statistics on: (1) establishing guidelines for inclusion of limited-English-proficient (LEP) students in the National Assessment of Educational Progress (NAEP), field tests, research, and development; (2) modifications in the…

A problem that arises when a differential item functioning (DIF) study is done with samples of examinees differing in ability is examined. A test may function differently when the populations from which the items are calibrated are not of equal ability. Since the lower ability examinees get many difficult items incorrect, the spread (standard…

This study investigated the extent to which log-linear smoothing could improve the accuracy of common-item equating by the chained equipercentile method in small samples of examinees. Examinee response data from a 100-item test (the Advanced Placement Examination in United States History) were used to create two overlapping forms of 58 items each,…

A review of the literature on writing in a non-native or second language looked at empirical research, responded to a series of questions on the state of the art, and identified an agenda for future research. The questions addressed these issues: how writing ability in a non-native language (NNL) develops: whether there are developmental stages;…

Most institutions of higher education have a mission that specifically addresses three areas: instruction, research, and service. The repertoire of activities and the complexity of the goals of the University Library mirror the goals of the institution, the academic units, and the faculty. The clients of the library are the students, the faculty,…

Faculty members in departments of chemistry, computer science, and education were surveyed to collect information on the content representativeness of the Graduate Record Examination (GRE) Advanced Tests in those disciplines. Faculty respondents allocated percentages to each of the major content categories of the specifications for the tests to…

This paper documents the achievement monitoring component of a three-year study on the acquisition of addition-subtraction problem-solving skills by young children. A set of performance objectives contained in or ancillary to ten instructional units on sentence-writing for verbal problems and algorithms specified test content. Tests measuring…

These tips on surveying public opinion are based on the contention that community surveys can be useful to educators who want to know what the community is thinking about education, are ready to respond, and have no qualms about making survey results public. The author first discusses the importance of determination of the community survey's…

This manual is designed to familiarize data users with the procedures followed for data collection and processing of the base-year school 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 files. The manual provides a wide range of…

Error profiles for the Fall Enrollment Survey of the Higher Education General Information Survey (HEGIS) were developed as part of an assessment of the quality of survey data. Three statistics were of particular interest: the count of full-time equivalent students, the breakdown by race/ethnicity, and the count of unclassified students. Attention…

It has been proposed that the National Assessment of Educational Progress (NAEP) increase its efforts to gather and analyze data on student background, teachers, households, and schools. Adoption of this proposal would result in the inclusion in NAEP of additional background variables and subpopulations, to be defined by states. NAEP specification…

Researchers conducted surveys of public attitudes in two Tennessee school systems in 1984-85 and 1985-86. Although interested in the survey results, one purpose of the researchers was to determine some inexpensive and relatively simple survey procedures. The researchers sought--through several pilot studies--to identify an efficient, parsimonious…

A statistical method has been developed for nested incomplete samples in a longitudinal study in which part of the sample has dropped out in such a way that the data have a nested pattern. A procedure which performed well in a Monte Carlo experiment was extended to a two-factor incomplete design with repeated measures on one factor. Methods…

Sampling distributions for ten tests for comparing population variances in a two group design were generated for several combinations of equal and unequal sample sizes, population means, and group variances when distributional forms differed. The ten procedures included: (1) O'Brien's (OB); (2) O'Brien's with adjusted degrees of freedom; (3)…

With the help of widely available microcomputers, it is possible to demonstrate certain statistical phenomena which students of statistics are usually expected to take on faith. Two demonstrations are described. In the first demonstration, three common types of sampling (simple random, biased, and stratified-random) are used to compare statistics…
