This study addresses validity issues in evaluation that stem from Ernest R. House's book, "Evaluating With Validity". The authors examine "American Journal of Evaluation" articles from 1980 to 2010 that report the results of policy and program evaluations. The authors classify these evaluations according to House's "major approaches" typology…

This article investigates three types of stage-sequential growth mixture models in the structural equation modeling framework for the analysis of multiple-phase longitudinal data. These models can be important tools for situations in which a single-phase growth mixture model produces distorted results and can allow researchers to better understand…

Student Evaluations of Teaching (SETs) play a central role in modern academia. They are used for tenure, promotion, teaching improvement and other important decisions. One would think that the data collected from a SET would be analysed correctly, but such is typically not the case, as can be seen in this study later. Therefore we propose a…

Purpose: This paper proposes a benefit of the doubt (BoD) approach to construct and analyse teacher effectiveness scores (i.e. SET scores). Design/methodology/approach: The BoD approach is related to data envelopment analysis (DEA), a linear programming tool for evaluating the relative efficiency performance of a set of similar units (e.g. firms,…

We estimated the invariance of educational achievement (EA) and learning attitudes (LA) measures across nations. A multi-group confirmatory factor analysis was used to estimate the invariance of educational achievement and learning attitudes across 55 nations (Programme for International Student Assessment [PISA] 2006 data, N = 354,203). The…

The purpose of this study was to investigate the application of the parallel analysis (PA) method for choosing the number of factors in component analysis for situations in which data are dichotomous or ordinal. Although polychoric correlations are sometimes used as input for component analyses, the random data matrices generated for use in PA…

This proof-of-concept investigation describes a computer-based approach for deriving the knowledge structure of individuals and of groups from their written essays, and considers the convergent criterion-related validity of the computer-based scores relative to human rater essay scores and multiple-choice test scores. After completing a…

With the continual progress of computer technologies, computer automated scoring (CAS) has become a popular tool for evaluating writing assessments. Research of applications of these methodologies to new types of performance assessments is still emerging. While research has generally shown a high agreement of CAS system generated scores with those…
