To date, only frequentist model-selection methods have been studied with mixed-format data in the context of IRT model-selection, and it is unknown how popular Bayesian model-selection methods such as DIC, WAIC, and LOO perform. In this study, we present the results of a comprehensive simulation study that compared the performances of eight…

There is a lack of published research examining ways to mitigate the effects of attention on human error prevalence in the marine setting. Evidence from the aviation industry, a very similar field, shows that attention does impact performance, especially when more than one task is to be completed at the same time. Much like pilots, mariners are…

The Bay View Alliance (BVA; https://bayviewalliance.org/) is a network of research universities working together to support and sustain the widespread adoption of instructional methods that lead to better student learning. The BVA's research action cluster on collaborative course transformation sought and received funding from the National Science…

Purpose: The aim of this study was to use the Daily Phonotrauma Index (DPI) to quantify group-based changes in the daily voice use of patients with phonotraumatic vocal hyperfunction (PVH) after receiving voice therapy as the sole treatment. This is part of an ongoing effort to validate an updated theoretical framework for PVH. Method: A…

Should educators encourage students to learn moral outrage in teaching about social (in)justice? If moral outrage is a catalyst for social change, to what extent can educators nurture this moral and political emotion in the classroom? These questions are at the heart of this essay. The aim is not to take sides for or against using moral outrage in…

Advances in information technologies present opportunities for novel approaches, methods, and tools for new or improved education and training practices. Furthermore, these technologies are enabling a shift in the education paradigm. Based on an investigation of a wide range of information technologies supporting smart education, we developed a…

Introductory organic chemistry laboratory is often a difficult course for students in terms of translating the structural information and reactivity learned in lecture to the practical applications found in the laboratory. These concepts are even more difficult when presented through distance learning when a student cannot get hands-on experience.…

This study aimed to examine the views of preservice science teachers on concept map use in a General Chemistry II class. The study was conducted with 47 preservice science teachers. In the study, an interview form grounded on determining their views on concept maps and comprised of open-ended questions, was used as the data collection tool. In…

Increasingly concerns are expressed about the formalisation of early childhood education and the loss of opportunities for children's play in a range of European and European heritage countries. This paper takes up this challenge by discussing, from a cultural-historical perspective, the relations between play and learning in pre-school settings.…

Encouraging students to actively ask questions during lectures is a formidable challenge that can be addressed through innovative use of information technology. We developed a robotic system that allows students in a lecture to collaboratively decide questions to be asked by a humanoid robot. To verify whether the system reduces hesitation to ask…

All children have the right to experience a safe and inclusive classroom that engages them in learning and advances equity. Writers' workshop is particularly well suited for creating a safe and inclusive space. Writers' workshop encourages children to share their own stories and listen to, learn about, and develop empathy for others. This…

In a well-known bronze plating experiment, a Cu coupon is subjected to Sn plating and heating with a Bunsen burner. Currently, aqueous NaOH or HCl is typically used as the plating solution; however, the use of a strong acid or base provides operational risks, particularly in educational settings (e.g., schools). Herein, we introduce a modified…

Balancing the competing demands of research and teaching has long been lamented by academics. The challenges associated with Covid-19 will make this increasingly difficult. An integrated approach to research and teaching, where students are directly engaged in the production of research, may provide a useful strategy to support ongoing research…

We are living in the Big Data era, and yet we may have serious troubles when dealing with a handful of kinetic data if we are not properly instructed. The aim of this paper, related to enzyme kinetics, is to illustrate how to determine the K[subscript m] and V[subscript max] of a michaelian enzyme avoiding the pitfalls in which we often fall. To…

Published healthcare cost estimates for children with autism spectrum disorder (ASD) vary widely. One possible contributor is different methods of case ascertainment. In this study, ASD case status was determined using two sources of parent reports among 45,944 children ages 3-17 years in the Medical Expenditure Panel Survey (MEPS) linked to the…
