Observational data typically contain measurement errors. Covariance-based structural equation modelling (CB-SEM) is capable of modelling measurement errors and yields consistent parameter estimates. In contrast, methods of regression analysis using weighted composites as well as a partial least squares approach to SEM facilitate the prediction and…

The literature showing that subscores fail to add value is vast; yet despite their typical redundancy and the frequent presence of substantial statistical errors, many stakeholders remain convinced of their necessity. This article describes a method for identifying and reporting unexpectedly high or low subscores by comparing each examinee's…

We present three strategies to replace the null hypothesis statistical significance testing approach in psychological research: (1) visual representation of cognitive processes and predictions, (2) visual representation of data distributions and choice of the appropriate distribution for analysis, and (3) model comparison. The three strategies…

This study examines the potential benefits of rhyme on young children's word retention during shared reading. In two experiments, 2- to 4-year-old children heard their parent read either a rhymed or non-rhymed version of the same animal story, and were then tested on how many animal names they subsequently recognized from the story in Experiment 1…

This paper investigates the impact of immigration on the college enrollment of U.S. natives. Many studies have focused on the effect of increased demand for schooling by immigrants on the enrollment of natives. However, changes in immigrant labor supply may also affect native enrollment by changing local market prices. Using U.S. Census data from…

Peer review of teaching is a collegial process designed to help academics reflect on and improve their teaching practice. Considerable research supports the value of peer review of teaching. However, uptake of voluntary programs is typically low. Few studies have examined the predictors of engagement in voluntary peer review. This study surveyed…

The purpose of this study was to assess the relative contribution of teacher and tutor ratings of inattentive behavior in two different instructional settings in predicting students' performance on fraction concepts and whole-number calculations. Classroom teachers rated each student's attentive behavior in a whole-class setting and tutors rated…

The current study examines three regression models: OLS (ordinary least square) linear regression, Poisson regression, and negative binomial regression for analyzing count data. Simulation results show that the OLS regression model performed better than the others, since it did not produce more false statistically significant relationships than…

This report provides an analysis of microcomputer software available for elementary and secondary level instruction in 1989 as compared to 1984. Data from the Resources in Computer Education (RICE) database are used to compare distribution of software programs by grade level; hardware manufacturer; application type (drill, tutorial, simulation,…

A study of the relationship between first-year results for 115 Dutch medical students and achievement during medical school was studied using an item-response theory model for the longitudinal measure of change with stochastic parameters (developed by Albers et al., 1989) indicates that a low rate of growth in the first year persists.
