This study investigated whether mean scores in school effectiveness ratings were masking poor delivery of educational services to low achievers in a sample of 242 Louisiana public elementary schools accounting for over 18,000 third graders tested in 1989. Ten separate multiple regression models, each producing studentized residuals used as school…

The psychological climate literature examines links between facets of climate, such as service orientation and a range of individual and organisational outcomes including work attitudes and performance. This study investigated the relationship between the service climate of an Australian university and outcomes important to its key stakeholders. A…

This study was designed to find: a suitable effect size (ES) measure or common metric (CM) for comparing the results of a set of single subject research (SSR) studies; and an easy way to convert the published graphs back into raw data from which ESs could be calculated. To meet the first objective, three possible formulas for measuring treatment…

Two methods of using collateral information from similar institutions to predict college freshman grade average were investigated. One central prediction model, referred to as pooled least squares with adjusted intercepts, assumes that slopes and residual variances are homogeneous across selected colleges. The second model, referred to as Bayesian…

Limitations of using linear, unilevel regression procedures in modeling student achievement are discussed. This study is a part of a broader study that is developing an empirically-based predictive model of variables associated with academic achievement from a multilevel perspective and examining the differences by which parameters are estimated…

Predictor weights estimated by using multiple linear regression are biased when there is restriction in the range (RR) of the dependent variable. Standardized multiple regression yields partial correlations as weights for the predictors, and these can be corrected for range difference between calibration and application samples. However,…

Correlations between the California Critical Thinking Skills Test--College Level (CCTST) and student-related factors regarded as indicators of academic ability and success were studied in a series of four experiments investigating whether the CCTST measures improvement in critical thinking (CT) skills. During 1989-90, data were collected on 1,196…

This study examined the value of the American College Testing Program (ACT) and secondary school performance as predictors of academic performance in college. Multiple regression was used to establish a prediction equation for grade-point average (GPA) at the end of the first term of the freshman year as the dependent variable and ACT and high…

This study investigated the relationships between maternal employment during three periods in the child's life, the child's self-concept, and family orientation. Variables statistically controlled were intactness of the family, father's employment status, the child's sex, the child's race, and the family's socioeconomic status. It was hypothesized…

Statistical significance is misused in educational and psychological research when it is applied as a method to establish the reliability of research results. Other techniques have been developed which can be correctly utilized to establish the generalizability of findings. Methods that do provide such estimates are known as invariance or…

A comparative budget analysis approach employed by British universities is discussed. The British funding system analyzes in detail unit costs and marginal costs and undertakes comparative assessments of expenditure patterns and priorities for a group of 95 institutions with similar objectives, in which each has autonomy in resource allocation.…

One factor which limits efforts to increase the number of black health professionals is performance in science courses at the college level. This study is one of several designed to identify factors which lead to success in the sciences at Xavier University of Louisiana, a small, historically black institution in New Orleans. The current…

To assess the effects of school traits on achievement, researchers reanalyzed the data used in "Public and Private Schools" (Coleman et al.) at the school level rather than the individual level. The data for the Coleman report and the present reanalysis are drawn from the "High School and Beyond" study, a 1980 national survey…

This study explored the assumption that the percentile rank of a group of students should be expected to remain the same on a post-test as on a pretest when the treatment of the group in the intervening period was the same as the treatment of the norms population. This assumption is basic to the use of the norm-referenced model for the assessment…

Title I evaluations using the RMC Model C design depend for their interpretation on the assumption that the regression of posttest on pretest is linear across the cut score level when there is no treatment; but there are many instances where nonlinearities may occur. If one applies the analysis of covariance, or model C analysis, large errors may…
