We extended current knowledge by examining the performance of several Bayesian model fit and comparison indices through a simulation study using the confirmatory factor analysis. Our goal was to determine whether commonly implemented Bayesian indices can detect specification errors. Specifically, we wanted to uncover any differences in detecting…

Classroom observation rubrics are a widely adopted tool for measuring the quality of teaching and provide stable conceptualisations of teaching quality that facilitate empirical research. Here, we present four statistical approaches for analysing data from classroom observations: Factor analysis, Rasch modelling, latent class or profile analysis,…

By design, randomized experiments (XPs) rule out bias from confounded selection of participants into conditions. Quasi-experiments (QEs) are often considered second-best because they do not share this benefit. However, when results from XPs are used to generalize causal impacts, the benefit from unconfounded selection into conditions may be offset…

This action research project sought to understand how giving students a choice in how to demonstrate mastery of a reading would affect both grades and evaluations of the instructor, given that assessment choice might increase student engagement. We examined the effect of student assessment choice on grades and course evaluations, the two…

Investigated factor structures of Wechsler Intelligence Scale for Children-Revised (WISC-R) and Kaufman Assessment Battery for Children (K-ABC) for 212 normal children. Findings suggest correspondence between: (1) WISC-R Verbal Comprehension and K-ABC Achievement; (2) WISC-R Perceptual Organization and K-ABC Simultaneous Processing; and (3) WISC-R…

The five studies reported on in this article investigated the effects of testing schemes on end-of-course achievement. Variables were frequency of testing, repeated or non-repeated tests, and single-unit or cumulative tests. Results are discussed. (Author/MT)

The purpose of this study was to compare the effects of four item selection rules--(1) Fisher information (F), (2) Fisher information with a posterior distribution (FP), (3) Kullback-Leibler information with a posterior distribution (KP), and (4) completely randomized item selection (RN)--with respect to the precision of trait estimation and the…

Examines the increase in popularity of objective testing in the United Kingdom and addresses some of the accompanying academic issues. Reports on a case study of test production and implementation to illustrate issues of time costs and benefits. Discusses question styles, marking schemes, and the problem of guesswork. (MJP)
