Creativity is increasingly identified as a key educational outcome at the local, regional, and national levels in several countries. Yet one key issue about the nature of creativity remains controversial: Whether creativity is domain specific or domain general. Resolving this issue would significantly impact the way creativity is identified,…

In research on the nature of science, there is a need to investigate the role and status of different scientific knowledge forms. Theories and models are two of the most important knowledge forms within biology and are the focus of this study. During interviews, preservice biology teachers (N = 10) were asked about their understanding of theories…

This article aims to provide a theoretical framework for computerized adaptive tests (CAT) and item response theory models for polytomous items. Besides that, it aims to introduce the simulation and live CAT software to the related researchers. Computerized adaptive test algorithm, assumptions of item response theory models, nominal response…

Although the rate of students with disabilities attending college continues to rise, these students often feel unprepared for college and graduate at discouraging rates. Further, negative outcomes are often exacerbated for college students with disabilities who experience co-occurring mental health needs. Although barriers associated with college…

A stronger understanding of the factors influencing implementation of interventions in community-based early childcare settings is needed. The purpose of this systematic review was to synthesize existing research on facilitators and barriers to implementation and sustainability of nutrition and physical activity interventions in early childcare…

Many theories and models describe the various cognitive processes individuals engage in as they solve ill-structured problems. While diverse in perspectives, these theories and models uniformly agree that essential aspects of complex problem solving include iteration and inquiry. This paper further argues that an important yet overlooked component…

Background: Engineers' identification with their profession is crucial for persistence among engineering students and career professionals. Significant research has been conducted on various dimensions of identity in the engineering field. However, little is known about the ways students negotiate these dimensions as they construct professional…

Diffusion-based item response theory models for responses and response times in tests have attracted increased attention recently in psychometrics. Analyzing response time data, however, is delicate as response times are often contaminated by unusual observations. This can have serious effects on the validity of statistical inference. In this…

Parametric methods, such as autoregressive models or latent growth modeling, are usually inflexible to model the dependence and nonlinear effects among the changes of latent traits whenever the time gap is irregular and the recorded time points are individually varying. Often in practice, the growth trend of latent traits is subject to certain…

Research surrounding library anxiety is plentiful; however, few studies have focused on distance or online learners and library anxiety. This article provides an overview of the construct library anxiety within distance learners and how library anxiety may impact their usage of academic library resources and services. First, it will explore…

This study investigates polytomous item explanatory item response theory models under the multivariate generalized linear mixed modeling framework, using the linear logistic test model approach. Building on the original ideas of the many-facet Rasch model and the linear partial credit model, a polytomous Rasch model is extended to the item…

Student affairs practitioners need to use theory or models to provide a framework for their work with college students. This article shows how a college campus practices leadership development within the Leadership Identity Development (LID) Model framework. In addition to providing steps for using the model in practice, some challenges are noted…

Reading aloud is recommended as a simple technique to measure speaking ability (Hughes & Hughes, 2020; Madsen, 1983). Reading aloud is currently used in the Pearson Test of English and a couple of other international English as a second language proficiency tests. Due to the simplicity of the technique, it can be used in conjunction with other…

The testlet comprises a set of items based on a common stimulus. When the testlet is used in the tests, there may violate the local independence assumption, and in this case, it would not be appropriate to use traditional item response theory models in the tests in which the testlet is included. When the testlet is discussed, one of the most…

Item response theory (IRT) models typically rely on a normality assumption for subject-specific latent traits, which is often unrealistic in practice. Semiparametric extensions based on Dirichlet process mixtures (DPMs) offer a more flexible representation of the unknown distribution of the latent trait. However, the use of such models in the IRT…
