Norm Block Sample Sizes: A Review of 17 Individually Administered Intelligence Tests.

TL;DR: In this article, the authors applied Kranzler and Floyd's method for estimating norm block sample sizes via a review of the most prominent, individually administered intelligence tests (10 full-length multidimensional tests, 4 nonverbal intelligence tests, and 3 brief intelligence tests).
Journal ArticleDOI

The Metacognitions Questionnaire and Its Derivatives in Children and Adolescents: A Systematic Review of Psychometric Properties

TL;DR: Based on initial data, it is suggested studies using younger populations should consider the Metacognitions Questionnaire-Child-30 but further psychometric research into this and other measures is needed.
Journal ArticleDOI

Evaluating the quality of teaching: can there be valid differentiation in the middle of the performance distribution?

TL;DR: Findings show that on almost all criterion variables, competent teachers outperformed basic teachers, but differences were usually small.
Journal ArticleDOI

The Impact of Test-Taking Disengagement on Item Content Representation

TL;DR: The current investigation reports the results of two studies focused on rapid-guessing behavior, showing evidence that differential rapid guessing often resulted in test events with meaningfully distorted content representation and implications for test-score validity.
Journal ArticleDOI

Evaluating Procedures for Reducing Measurement Error in Math Curriculum-Based Measurement Probes

TL;DR: In this paper, the authors compared a set of commercially available probes (i.e., AIMSweb) with an experimental set that was constructed to enhance consistency in item content across alternative forms.

Cutoff criteria for fit indexes in covariance structure analysis : Conventional criteria versus new alternatives

TL;DR: In this article, the adequacy of the conventional cutoff criteria and several new alternatives for various fit indexes used to evaluate model fit in practice were examined, and the results suggest that, for the ML method, a cutoff value close to.95 for TLI, BL89, CFI, RNI, and G...

Convergent and discriminant validation by the multitrait-multimethod matrix.

TL;DR: This transmutability of the validation matrix argues for the comparisons within the heteromethod block as the most generally relevant validation data, and illustrates the potential interchangeability of trait and method components.

Evaluating Goodness-of-Fit Indexes for Testing Measurement Invariance

TL;DR: In this paper, the authors examined the change in the goodness-of-fit index (GFI) when cross-group constraints are imposed on a measurement model and found that the change was independent of both model complexity and sample size.

A Review and Synthesis of the Measurement Invariance Literature: Suggestions, Practices, and Recommendations for Organizational Research

TL;DR: The establishment of measurement invariance across groups is a logical prerequisite to conducting substantive cross-group comparisons (e.g., tests of group mean differences, invariance of structura, etc.).
