This paper was intended to promote a deeper understanding of a statistical method called balancing developed by National Assessment of Educational Progress. Problems in estimating main effects when populations are disproportionate, balancing solutions to these problems, methods equivalent to balancing, interpretation of balanced results, and some…

Researchers studying monitoring accuracy currently use two different indexes to estimate accuracy: relative accuracy and absolute accuracy. The authors compared the distributional properties of two measures of monitoring accuracy using Monte Carlo procedures that fit within these categories. They manipulated the accuracy of judgments (i.e., chance…

The VARAN (variance Analysis) program is an addition to a series of computer programs for multivariate analysis of variance. The development of VARAN exploits the full linear model. Analysis of variance, univariate and multivariate, is the program's main target. Correlation analysis of all types is available with printout in the vernacular of…

An iterative least squares procedure for analyzing the effect of various kinds of intervention in time-series data is described. There are numerous applications of this design in economics, education, and psychology, although until recently, no appropriate analysis techniques had been developed to deal with the model adequately. This paper…

This paper is about the structural equation modelling of quantitative measures that are obtained from a multiple facet design. A facet is simply a set consisting of a finite number of elements. It is assumed that measures are obtained by combining each element of each facet. Methods and traits are two such facets, and a multitrait-multimethod…

Three attributes of faculty competence--teaching, research, and service--were each measured by three different instruments--department chair evaluation, self-evaluation, and one other measure (student evaluations, number of publications, or number of committees). The data were analyzed through a multitrait-multimethod matrix (MTMMM) to ascertain…

A reporting and study format for the investigation of university student retention is presented. Student progression and loss is shown graphically and in tabular form to enable ready comprehension and encourage data exploration. Data obtained at Virginia Commonwealth University for 1977-80 are used as illustration. Two ways of viewing student…

This is one of a series of reports on the National Longitudinal Study of Mathematical Abilities (NLSMA). This one is a summary of NLSMA Reports Nos. 21-25, presented as an aid in searching for patterns across various correlates, various mathematical achievement measures, and various samples. In the original analyses, students were grouped into…

Tabular procedures for analyzing open-ended responses were used to study a school district's educational reform program. Responses of a rural Arizona Career Ladder (CL) school district's teachers and administrators to three pairs of open-ended questions contained in the 1989 Perception Assessment Scale survey comprised the data base for the…

TAILOR is a computer program that uses the implied orders concept as the basis for computerized adaptive testing. The basic characteristics of TAILOR, which does not involve pretesting, are reviewed here and two studies of it are reported. One is a Monte Carlo simulation based on the four-parameter Birnbaum model and the other uses a matrix of…

In this analysis of cases and clauses in Vietnamese, an attempt is made to make use of tagmemics and a case grammar model called lexicase. Such an eclectic combination of the two theories is not new either in the field of general linguistics or in Vietnamese. This paper recognizes the hierarchical levels in syntax and the grammatical unit or…

The increased use of criterion-referenced statewide testing programs is an outgrowth of the need for more diagnostic information for planning and decision making than is provided by norm-referenced programs. There remains, however, a need for state agencies to compare the results of local districts to a variety of comparison groups for the purpose…

The family of Weibull distributions was investigated as a model for the distributions of response times for items in computer-based criterion-referenced tests. The fit of these distributions were, with a few exceptions, good to excellent according to the Kolmogorov-Smirnov test. For a few relatively simple items, the two-parameter gamma…

Forming a sequence covering the various aspects of the simplex model, four articles are presented here under the following titles: "A Simplex Model for Analyzing Academic Growth", "Analyzing Ratings With Correlated Intrajudge Measurement Errors", "The Correlation of States With Gain", and "The Reliability of…

This volume contains the appendices to a study to determine which patterns of classroom interaction and student characteristics were related to students' acquisition of oral proficiency in English. Participants were the English as a second language teachers and students at the West New York (New Jersey) Adult Learning Center. Student measures, a…
