Multidimensional item response theory (MIRT) models have generated increasing interest in the psychometrics literature. Efficient approaches for estimating MIRT models with dichotomous responses have been developed, but constructing an equally efficient and robust algorithm for polytomous models has received limited attention. To address this gap,…

The historical context of education in the United States reveals a consistent failure by American schooling to effectively educate Black boys. Multiple indicators of how Black male students are underserved have necessitated interventions to reverse decades of adverse outcomes. The single-gender school design became one such intervention dedicated…

Postgraduate output is important in any country's knowledge development and their knowledge economy. The development of postgraduate output especially at master's and PhD levels in South Africa is at risk due to its slow pace. An argument that can be made is that undergraduate experiences lend to postgraduate access and success. This article…

The gold-standard for evaluating the effect of an educational intervention on student outcomes is running a randomized controlled trial (RCT). However, RCTs may often be small due to logistical considerations, and resulting treatment effect estimates may lack precision. Recent methods improve experimental precision by incorporating information…

Student attitudes toward science have been one of the longstanding topics in science education research. Even though Indonesia has a unique educational system in which cultural, religious, and cognitive aspects are incorporated in the science K-12 curriculum, a limited number of studies have explored Indonesian students' attitudes towards science.…

Purpose: This paper aims to share findings from an interview study with literacy educators who are working together to imagine and build a transformative, humanizing and expansive education. Design/methodology/approach: Appreciative inquiry is a design and process that seeks ways to discover the potential of educators while also affirming what…

The "nomor acak" learning model is done by randomly giving number to each student and making them remember it from the beginning to the end of the lecture. The function was to make each student be more active in the teaching and learning activities, since they must be prepared with their respective material if the number was called. This…

In order to promote the design of innovative instructional activities at the Linear Algebra, we perform a design-based research project to explore how to teach Linear Algebra at the university level. In this article, we present the results of three cycles of a teaching experiment that we carried out to design, try out, and improve a local…

Network meta-analysis (NMA) uses both direct and indirect evidence to compare the efficacy and harm between several treatments. Structural equation modeling (SEM) is a statistical method that investigates relations among observed and latent variables. Previous studies have shown that the contrast-based Lu-Ades model for NMA can be implemented in…

We propose that by more closely aligning interdisciplinary work in (a) numeracy education for medication dosage calculations and (b) model-driven design for medical devices that are used for delivery of medication we may help address the incident-rate in incorrect medication calculations and delivery, given that such devices commonly require the…

Sustained attention (SA) and short-term memory (STM) contribute to language function in Down syndrome (DS). We proposed models in which relations of SA to language in DS are mediated by STM. Thirty-seven youth with DS aged 10-22 years (M = 15.59) completed SA, STM, and language tasks. Cross-sectional mediation analyses were run with the…

Purpose: Inclusive organizations believe in integrating all toward synergistic outcomes. However, the extent to which inclusive education plays their role toward inclusive organizations requires more explorations. Therefore, the purpose of this paper is to provide a theoretical model exploring authentic leadership (AL) as a predictor of inclusive…

The Learning study and the Educational Action Research approaches to educational research are compared, not from a third, neutral point of view, but from the perspective of the former. Hence, the comparison is carried out in terms of how the main point of departure of the Learning study (LS), the question of 'What is to be learned?', is addressed…

In this article, the authors present a 5E learning cycle for fifth grade that focuses on using a model of matter to explain the properties they observe, and how those properties can help identify whether two objects are made of the same type of matter. That model also helps explain phenomena such as why a specific material floats, no matter how…
