Abstract Vocabulary knowledge plays a crucial role in L2 proficiency, significantly impacting learners' reading comprehension. Although extensive research has explored whether knowledge of base words extends to recognition of derivational forms, results are inconsistent, especially among learners from non‐Indo‐European linguistic backgrounds.

Index Insurance and Food Security Among Smallholder Farmers in Southern Mali
ABSTRACT Climate extremes increasingly threaten food security in low‐ and middle‐income countries, where vulnerable smallholder farmers often lack access to risk mitigation tools. Although index‐based insurance has been promoted as a promising adaptation measure to climate shocks, evidence on its welfare effects, especially on food security, remains ...

Comparison of Scale Identification Methods in Mixture IRT Models [PDF]
The effects of three scale identification constraints in mixture IRT models were studied. A simulation study found no constraint effect on the mixture Rasch and mixture 2PL models, but the item anchoring constraint was the only one that worked well on ...

Abstract Purpose To assess the vision‐related quality of life (VRQoL) in glaucoma patients over 5 years after primary Baerveldt glaucoma implant (BGI) or trabeculectomy (TE) using a secondary analysis of a randomized clinical trial. Methods Patients were randomized to undergo TE or receive a BGI.

Anchor methods for DIF detection: A comparison of the iterative forward, backward, constant and all-other anchor class [PDF]
In the analysis of differential item functioning (DIF) using item response theory (IRT), a common metric is necessary to compare item parameters between groups of test-takers.

This review found a general association between sleep and reading ability in children, though some sleep outcomes are more robustly associated with reading than others. The strongest links between sleep and reading are seen in behavioural sleep outcomes, including general sleep disturbances, insomnia symptoms, sleep‐disordered breathing, daytime ...

Abstract Given the increasing integration of Artificial Intelligence (AI) into everyday life and professional contexts, it is essential to investigate learners' existing capabilities regarding AI tools to inform possible interventions to equip them with necessary AI skills, but also advance the theoretical frameworks on digital skills measurement and ...

IRT‐based response style models and related methodology: Review and commentary
Abstract We provide a review and commentary on recent methodological research related to item response theory (IRT) modelling of response styles in psychological measurement. Our review describes the different categories of IRT models that have been proposed, their associated assumptions and extensions, and the varying purposes they can serve.

Comparing two maximum likelihood algorithms for mixture Rasch models
The mixture Rasch model is gaining popularity as it allows items to perform differently across subpopulations and hence addresses the violation of the unidimensionality assumption with traditional Rasch models. This study focuses on comparing two common maximum likelihood methods for estimating such models using Monte Carlo simulations. The conditional

Latent Poisson count models for action count data from technology‐enhanced assessments
Abstract Recent advances in computerized assessments have enabled the use of innovative item formats (e.g., drag‐and‐drop, scenario‐based), necessitating a flexible model that can capture systematic influence of item types on action counts. In this study, we present a refinement scheme that can explicitly model common features of items and allows ...
