The fit of an item response model is typically conceptualized as whether a given model could have generated the data. We advocate for an alternative view of fit, "predictive fit", based on the model's ability to predict new data. We derive two predictive fit metrics for item response models that assess how well an estimated item response…

Program administrators must be intentional when hiring faculty and selecting electives in order to hire faculty the students will be able to relate to, perceive as role models, and who will be able to provide students in higher education in prison (HEP) programs with knowledge about racial issues in our society often from personal experience.…

As an alternative to the traditional metallocene laboratory targets, students synthesize Cp[subscript 2]TiCl[subscript 2], bis([eta][superscript 5]-cyclopentadienyl)dichloridotitanium(IV), from the mildly moisture-sensitive cis-TiCl[subscript 4](thf)[subscript 2]. Air-free handling techniques are emphasized, but the (mostly) air-stable,…

Structural equation modeling (SEM) and path analysis using composite-scores are distinct classes of methods for modeling the relationship of theoretical constructs. The two classes of methods are integrated in the partial-least-squares approach to structural equation modeling (PLS-SEM), which systematically generates weighted composites and uses…

I provide considerations for TPC instructors and programs regarding developing students' IC skills.I start by examining key conversations and found that issues teaching IC arise when frameworks, texts, and/or individuals do not define key terms related to culture and IC. To address this issue and create a strong foundation, I establish some of the…

Testing programs have explored the use of technology-enhanced items alongside traditional item types (e.g., multiple-choice and constructed-response items) as measurement evidence of latent constructs modeled with item response theory (IRT). In this report, we discuss considerations in applying IRT models to a particular type of adaptive testlet…

In this paper, we share our collaboration across the disciplines of mathematics and mathematics education to develop and implement a mathematical modeling task for prospective secondary mathematics teachers. Through this collaboration, we identified three key components of mathematical modeling: the "what," "how," and…

Factor mixture modeling (FMM) is generally complex with both unobserved categorical and unobserved continuous variables. We explore the potential of item parceling to reduce the model complexity of FMM and improve convergence and class enumeration accordingly. To this end, we conduct Monte Carlo simulations with three types of data, continuous,…

Feedback is an essential part of the educational assessment that improves student learning. As education changes with the advancement of technology, educational assessment has also adapted to the advent of Artificial Intelligence (AI). Despite the increasing use of online assessments during the last decade, a limited number of studies have…

This article presents and evaluates a model made for climate change education -- the bicycle model. The model was created based on an extensive literature review, from which, essential aspects of climate change education were drawn out. The bicycle model is a representation of holistic climate change education and emphasizes the importance of the…

The relationship between autistic traits, stress, and anxiety experienced by the general population was investigated using an adult sample that evaluated the suitability of three theoretical models proposed by Green and Ben-Sasson. Participants completed online questionnaires that were analysed using structural equation modelling and partial…

This quantitative research study sought to examine the differences in retention and degree attainment for college students depending on their home locale and the location of their institution of attendance. Students were divided into four groups: rural students who attended a rural institution, rural students who attended an urban institution,…

This paper provides some insights into the use of example-generating tasks in the design of a technology-rich learning environment to enhance students' mathematical thinking. The paper reports on an early stage of a design-based research project concerning the design of tasks and associated feedback utilising the affordances provided by a combined…

This study examined how technology integration in teacher training programs affects cultural and linguistic competency development among pre-service instructors. Based on the Cultural Competence Theory and the Technological Pedagogical Content Knowledge TPACK model, this research utilized a systematic literature review approach to integrate…

The Impact Agenda, introduced with Research Excellence Framework 2014 (REF), constituted a revolution in research evaluation in the UK. 'Research impact' (impact of scholarly work outside of academia) became one of three profiles under which research quality is evaluated. This shift in the British evaluation system was followed, and often…
