How do cultural heritage scientists and art conservators identify pigments and other painting media in a decorated object or painting, preferably without taking samples that could potentially damage the artwork? A major emphasis in the characterization, authentication, and conservation of works of art and cultural heritage objects is the use of…

One educational technology that is worth a look is Google's G-Suite for Education (GS-E). Google has invested a great deal in GS-E and publicizes it as a full-fledged member of Google's family of suites. GS-E comprises Classroom, which acts as the course hub, while the entire suite of other Google products such as Docs, Calendar, Sheets, Hangouts,…

This contribution shows a simple implementation of Monte Carlo simulation method when presenting Bayes' rule. The implementation is carried out in the environment of Microsoft Excel spreadsheets by means of a generator of random numbers. The empiric results gained by simulation serve to confirm the correctness of the chosen procedures in…

This article provides an overview of the R package lsasim, designed to facilitate the generation of data that mimics a large scale assessment context. The package features functions for simulating achievement data according to a number of common IRT models with known parameters. A clear advantage of lsasim over other simulation software is that…

Ten years after the announcement of the "rise of the super experiment" at Educational Data Mining 2012, challenges to implementing "internet scale" educational experiments often persist for educational technology providers, especially when they seek to test substantive instructional interventions. Studies that deploy and test…

In a context where current forms of governance and polity across many societies are engaging with 'platformisation', the paper argues that the utility and consequences of using a theory of pedagogy can provide a different way to explain how digital technology might 'determine' subjectivity. This paper describes the key process of how platforms…

In this paper, we describe the design, development, and implementation of a curriculum based on teaching computer science using an industry-standard game-design software: Unity 3D. We discuss the theoretical underpinnings of our instructional design process and steps we have taken to introduce complexity and maintain student motivation. We discuss…

While job interviewing training is part of the transition planning and school-to-work curriculum, using virtual reality (VR) can be a valuable addition to the current curriculum, specifically given the unique characteristics of individuals with ASD. This article will provide step-by step procedures to integrate VR into the current classroom…

Peer review has been promoted for decades in order to engage students in the assessment process which then leads to better learning outcomes. This teaching pedagogy is relatively innovative in the Hong Kong language classroom because English as a Second Language (ESL) students are not aware of their responsibility in the language learning process…

Generative artificial intelligence (GenAI) such as ChatGPT, as well as educational technology (EdTech) powered by GenAI, have the potential to improve learning outcomes for all students. However, teachers, school leaders and education policymakers are grappling with questions about how to navigate the potential benefits and risks of using this…

This report aims to introduce the fundamental features of the free Jamovi software to academics in the field of educational measurement for use at undergraduate and graduate level research. As such, after introducing the R based interface and the integrated development environment, the core functions of Jamovi are presented, the installation for…

Today smartphones are inseparable parts of modern life and are capable of performing many desktop computers' tasks such as scientific analysis with greater convenience. Here, we present OligoCOOL, which is an Android application for analyzing nucleic sequences. This application enables users to perform several common biomedical analyses for a…

The R software provides packages and functions that provide data analysis in classical true score, generalizability theory, item response theory, and Rasch measurement theories. A brief list of notable articles in each measurement theory and the first measurement journals is followed by a list of R psychometric software packages. Each psychometric…

Since the initial recognition that human knowledge is structured in a relational manner, technologies have been developed for assessing and analyzing the "structure" of knowledge for a variety of purposes. A computer-based text analytic offline software system, "ALA-Reader," that was developed to assess this knowledge structure…

This case describes the redesign of a mobile eReader application. The purpose of the redesign was to convert an existing eReader from a means of only reading books into a tool for informal learning. The case reports how the design team's definition of informal learning evolved throughout the product development process, and how design decisions…
