This article presents the performance of item response theory (IRT) models when double ratings are used as item scores over single ratings when rater effects are present. Study 1 examined the influence of the number of ratings on the accuracy of proficiency estimation in the generalized partial credit model (GPCM). Study 2 compared the accuracy of…

Testing item fit is central in item response theory (IRT) modeling, since a good fit is necessary to draw valid inferences from estimated model parameters. "Infit" and "outfit" fit statistics, widespread indices for detecting deviations from the Rasch model, are affected by data factors, such as sample size. Consequently, the…

This research evaluates a novel, modular, open-source, and low-cost educational robotic platform in Educational Robotics and STEM Education. It is the sequel of an action research cycle on which the development of this robot is based. The impetus for the need to develop this came from the evaluation of qualitative and quantitative research data…

Publication of research outputs is a method of researchers to capture their knowledge generated. Analysing the publication topics and trends in a research field can provide insight into the main research trends. A bibliometric analysis, based on the topics from published literature, provides insight into the focus areas and trends of a research…

Both a student-centered instruction approach and a classroom management technique based on the learning protocol are known as protocol-guided learning. This paper describes the protocol-guided learning model's implications for classroom practice and its impacts on classroom reconstruction with the aim of ensuring that learning actually occurs on…

This study of a return to in-person learning during the COVID-19 pandemic at a residential, liberal arts university examines the role communication played to facilitate the safety of students, faculty, staff, and the surrounding community. The study uses a grounded-theory approach to frame the communication situation, and a thematic analysis to…

In early childhood education, the integration of science, technology, engineering, arts, and mathematics (STEAM) are advocated as contemporary educational goals. However, integration of STEAM is not defined in the early childhood context. We claim to 'integrate' and 'devise integration pedagogies', but there is still no clear-cut message on what…

In Ireland, physical education (PE) in the first three years of second level (12-15 years) is taught within the broader program area of Wellbeing, which necessarily influences the aims and objectives which need to be achieved. Within this context, Y-PATH PE4Me is proposed as an underpinning curriculum model to serve as an appropriate and valuable…

Prairie View A&M University (PVAMU) plays an important role in the social and economic life of the local, state and national economy. This study presents estimates of the economic impacts of the University's contributions, both short-term and long-term, on the local (Waller County), regional (Houston-The Woodlands-Sugar Land Metropolitan…

Questionnaires inquiring about psychopathology symptoms often produce data with excess zeros or the equivalent (e.g., none, never, and not at all). This type of zero inflation is especially common in nonclinical samples in which many people do not exhibit psychopathology, and if unaccounted for, can result in biased parameter estimates when…

When fitting unidimensional item response theory (IRT) models, the population distribution of the latent trait ([theta]) is often assumed to be normally distributed. However, some psychological theories would suggest a nonnormal [theta]. For example, some clinical traits (e.g., alcoholism, depression) are believed to follow a positively skewed…

Studies indicate that learners' cognitive style (CS), self-regulated learning (SRL), and working memory (WM) are associated with their academic performance. These studies describe the relationship of academic achievement with SRL, CS, or WM individually or pairwise relationships between SRL, CS, and WM rather than the overall relationship between…

Longitudinal data analysis has been widely employed to examine between-individual differences in within-individual changes. One challenge of such analyses is that the rate-of-change is only available indirectly when change patterns are nonlinear with respect to time. Latent change score models (LCSMs), which can be employed to investigate the…

Many countries and regions have reached a consensus to promote science, technology, engineering, and mathematics (STEM) education in the past decade. A body of studies have demonstrated that the design and organization of interdisciplinary teaching activities are important for the effective implementation of STEM education. So far, however, little…

This study explored the mediating role of mathematics anxiety in the relationship between TPACK competencies and mathematics teaching anxiety. This mediation role was tested through structural equation modeling using data from 426 pre-service mathematics teachers selected through criterion sampling. TPACK Competencies Scale, Mathematics Anxiety…
