This report from the Senate Library Committee at the University of Pittsburgh evaluates a widely publicized study of monograph and periodical use conducted at Pitt by Professor Allen Kent and his associates from 1975-1977. Areas of the study which are examined include structure in text and footnotes, and experimental design, execution, and…

To investigate the effect of violating the assumption of equal item difficulty on Kuder-Richardson (KR) Formula 21 reliability coefficient, 670 eighth-and ninth- grade students were administered 26 short, homogeneous "tests" of mathematics concepts and skills. Both KR Formula 20 and KR Formula 21 were used to estimate reliability on each…

Achievement tests which are specifically linked to an instructional program and have been developed in relation to an objectives base and/or to an item generation rule are considered, as well as student response data. Three types of studies are outlined and the kind of procedures thought useful illustrated. As various methods for examining…

Described and listed herein with concomitant sample input and output is the Fortran IV program which estimates parameters and standard errors of estimate per parameters for parameters estimated through multiple matrix sampling. The specific program is an improved and expanded version of an earlier version. (Author/BJG)

Intended for employers concerned about problem solving and communication within their organization, this document outlines a strategy for developing an instrument that would provide objective data rather than impressionistic data. A questionnaire was designed to explore the relationship between the central constructs of problem solving and…

This study was designed to determine the relative impact of dichotomized task performance data compared to percent time-spent estimates for those members performing each task on the group job descriptions determined through application of the Comprehensive set of Occupational Data Analysis Programs (CODAP). Using groups identified by a routine…

The Washington Principal Evaluation Inventory provides a measure of principal effectiveness. Not only does the inventory yield a total measure of overall principal effectiveness, but also meaningful scores for each of seven dimensions of administrator behavior. The inventory consists of 64 statements of principal behavior on which teachers and…

This report describes the development of the 1969-70 Michigan Educational Assessment measures used in assessing the levels and distribution of educational performance for Michigan's districts, schools, and pupils. The report has four sections. The first section contains a brief description of the 1969-70 assessment program, including a statement…

The P.E.P. Report 1969-1973 focuses on the various findings and activities of the Program Evaluation Project. The study in this chapter was designed to conduct a statistical analysis of the Goal Attainment Score, and estimate variance components due to choice of material in the followup guide, followup interviewer bias or error, and the client's…

Data from the national evaluation of Project Follow Through were analyzed using analysis of covariance with and without correcting the pretest for unreliability. Such corrections led to some changes in conclusions. There are many disagreements in the literature about the appropriateness of correction for unreliability. (Author/CTM)

A procedure is presented for the analysis of rating data with correlated intrajudge and uncorrelated interjudge measurement errors. Correlations between true scores on different rating dimensions, reliabilities for each judge on each dimension and correlations between intrajudge errors can be estimated given a minimum of three raters and two…

The Stanford Preschool Internal-External Scale (SPIES) was administered to middle class kindergarten children to investigate whether the characteristics of the test would remain stable as it did for the normative sample. (Author/DEP)

Since judgments of teaching and teachers should be distinguished, six arguments for using the students' opinions are reviewed and three counter-arguments are presented. It is shown that many previous validity studies are based upon a logical error and that none justifies the validity of students' opinions of teaching. Subjectivity may be the cause…

Demonstrating good reliability for the difference score in measurement, the results of this study indicate that the difference score is often highly reliable when the correlation between true change and true initial status is nonnegative. In general, when individual differences in true change are appreciable, the difference score shows strong…

Maximum likelihood factor analysis provides an effective method for estimation of factor matrices and a useful test statistic in the likelihood ratio for rejection of overly simple factor models. A reliability coefficient is proposed for analysis of factor solution. (Author/RK)
