Background: The relation between academic self-concept and achievement has been examined in a large number of studies. The majority of these studies have found evidence for a reciprocal effects model. However, there is an ongoing debate on how students' achievement should be measured and whether the type of achievement indicator (grades, tests,…

Two pitfalls are identified in the use of arithmetic averages for performance measurement in higher education. First, asymmetric average targeting rules involve a fallacy of composition; and, second, comparisons with adjusted averages involve a serious methodological error. (DB)

A reliable "news morbidity" scale was developed to measure the prevalence of bad and good news on radio and television; the scale was then used in a pilot study of one city's news output. The news morbidity scale is a seven-step scale ranging from "extremely bad" to "extremely good" news. A sample of 945 television…

This study examined the comparability and predictive validity of three approaches to measurement of child or adolescent maltreatment, involving the adolescents themselves (n=160), case file review by researchers, and protection agency social workers. Comparison of ratings across sources indicated considerable disagreement with respect to judgments…

Using three distinct indicators of well-being, differences and similarities are examined between a Wyoming boom town and a Utah non-boom community. Results provide evidence of disruption on only one indicator and highlight the importance of disaggregating boom town populations into distinct subpopulations when assessing effects of rapid growth.…

Two methods of 'equating' tests using item response theory (IRT) are compared, one using true scores, the other using the estimated distribution of observed scores. On the data studied, they yield almost indistinguishable results. This is a reassuring result for users of IRT equating methods. (Author)

Pratt's measure C on the class concentration of bibliometric distributions is calculated and interpreted for the laws of Zipf, Mandelbrot, and Lotka and geometric distribution, and comparisons are made of the results. An explicit mathematical formula which unifies disparate theories is derived and tested. (Author/CLB)

Presents a measure of the relative standing of professional journals in an aggregated journal citation matrix. The results of the application of the measure to a network of geographic journals during two time periods are reported and discussed. (35 references) (Author/CLB)

The purpose of this study was to develop a single procedure for comparing population variances which could be used for distribution forms. Bootstrap methodology was used to estimate the variability of the sample variance statistic when the population distribution was normal, platykurtic and leptokurtic. The data for the study were generated and…

Four different systematic methods for selecting passing scores which differ primarily in the types of judgment they require were compared. The borderline group method and the contrasting groups method were each compared with the Nedelsky method at four schools and the Angoff method at another four schools. The Basic Skills Assessment Tests in…

This study explored how logit, probit, and more traditional linear regression techniques compare in predicting college student retention, using data provided by registrars from a national sample of colleges and universities. Results showed little practical difference among the techniques, despite theoretical advantages offered by the first two.…

An alternative procedure is examined to compare test scores which does not require the utilization of computers and therefore, can be easily employed by classroom teachers. This technique is called the Average System: a simple way to score examinees using information obtained from a representative sample (or samples). Examinees are ranked on a…

Discusses the results of an ongoing research study to measure college students' microcomputer literacy before taking a microcomputer course. A brief review of the literature on computer literacy is provided, a comparative analysis of results is given, and a microcomputer literacy index is described that measures literacy and ranks students.…

Addresses applications of the coefficient of variation as a measure of educational inequality or as a means of measuring changes of inequality status. Suggests the Gini coefficient has many advantages over the coefficient of variation since it can be used with the Lorenz curve (Lorenz provides detail Gini omits). (BRR)

Examines a new approach to university economic impact research that views institutional expenditures as a means to increase the state's skill base, and finds that while the approach yields favorable results for higher education it fails to consider fully the effects of migration. Advises researchers to avoid this approach and use the traditional,…
