Does random differential item functioning occur in one or two groups? Implications for bias and variance in asymmetric and symmetric Haebara and Stocking-Lord linking [PDF]

Asymmetry
Linking methods are frequently applied to analyze the performance of two groups on a set of items. This article shows analytically and by simulation that the occurrence of differential item functioning (DIF) can induce bias and additional variance in ...

Comparing different trend estimation approaches in country means and standard deviations in international large-scale assessment studies

Large-scale Assessments in Education, 2023
One major aim of international large-scale assessments (ILSA) like PISA is to monitor changes in student performance over time. To accomplish this task, a set of common items (i.e., link items) is repeatedly administered in each assessment.

Model-Data Fit using Akaike Information Criterion (AIC), Bayesian Information Criterion (BIC), and The Sample-Size-Adjusted BIC

, 2022
The study determined if the 1PL, 2PL, 3PL and 4PL item response theory models best fit the data from the 2016 NECO Mathematics objective tests. Ex-post facto design was adopted for the study.

Examining the relation of correct knowledge and misconceptions using the nominal response model

Physical Review Physics Education Research, 2021
This study reports an analysis of the Force Concept Inventory (FCI) using item response curves (IRC)—the fraction of students selecting each response to an item as a function of their total score.

Reading Comprehension Tests for Children: Test Equating and Specific Age-Interval Reports

Frontiers in Psychology, 2021
Equating is used to directly compare alternate forms of tests. We describe the equating of two alternative forms of a reading comprehension test for Brazilian children (2nd to 5th grade), Form A (n = 427) and Form B (n = 321).

Application of Asymmetric IRT Modeling to Discrete-Option Multiple-Choice Test Items

Frontiers in Psychology, 2018
Asymmetric IRT models have been shown useful for capturing heterogeneity in the number of latent subprocesses underlying educational test items (Lee and Bolt, 2018a).

Parameter Estimation Accuracy of the Effort-Moderated IRT Model Under Multiple Assumption Violations

, 2020
As low-stakes testing contexts increase, low test-taking effort may serve as a serious validity threat. One common solution to this problem is to identify noneffortful responses and treat them as missing during parameter estimation via the Effort ...

The complexity of neighborhood effects: A developmental and ecological framework for violent victimization

Criminology, EarlyView.
Abstract Extensive research has established a link between low self‐control and child victimization. However, the specific neighborhood conditions under which low self‐control most strongly influences victimization have been little examined, and, more importantly, no previous studies have investigated the complex ways in which neighborhood context ...
