Digital mediation strategies are key soft skills to develop amongst students as they prepare to interact in increasingly collaborative settings, socially and professionally. Defined as a set of communication strategies deployed to reach mutual agreement over a dispute, mediation enables students' cooperation in task-based language teaching…

The emergence of generative artificial intelligence (GenAI) has ignited debates regarding its potential benefits and detriments for education. Despite widespread discussions, insights into GenAI's impact on education have been limited because early studies have often been narrow in scope and focused on specific contexts. Therefore, the purpose of…

It has been discovered that incorporating technology into geometry instruction improves students' abilities and attitudes. GeoGebra Software is effective at motivating teachers to use technology as a supplement to enhance students' mathematical learning potential. The current study sought to ascertain the effects of GeoGebra software on secondary…

In this paper, to handle the problem of the quick evolution of cyber-security attacks, we developed the iMonsters board game and proposed the attack and defense knowledge self-evolving algorithm. Three versions of the iMonsters were launched in 2013, 2017, and 2019, respectively. Accordingly, the cyber-security ontology can be refined by the…

Modern technology plays an important role in helping students from all walks of life to overcome barriers and benefit from teaching and learning. However, due to a lack of knowledge or skills with regards to educational technologies, K-12 teachers struggle to harness the full potential of digitalisation to support student learning and engagement,…

This thesis explores the use of Augmented Reality (AR) in two challenging scenarios -- autism therapy, and network-constrained, remote collaboration. In the first half of this thesis, we highlight the design and implementation of CustomAR and Augmented Playgrounds -- two applications that leverage the visualization and contextual abilities of AR…

Teachers often rely on the use of a range of open-ended problems to assess students' understanding of mathematical concepts. Beyond traditional conceptions of student open-ended work, commonly in the form of textual short-answer or essay responses, the use of figures, tables, number lines, graphs, and pictographs are other examples of open-ended…

Large language models (LLMs), such as Codex, hold great promise in enhancing programming education by automatically generating feedback for students. We investigate using LLMs to generate feedback for fixing syntax errors in Python programs, a key scenario in introductory programming. More concretely, given a student's buggy program, our goal is…

Automatically identifying struggling students learning to program can assist teachers in providing timely and focused help. This work presents a new deep-learning language model for predicting "bug-fix-time", the expected duration between when a software bug occurs and the time it will be fixed by the student. Such information can guide…

As social media apps, gaming platforms, and other online environments have given present more opportunities to adolescents to cause harm to their peers, the proportion of youth who have experienced cyberbullying continues to rise. This bestselling guide from the co-directors of the Cyberbullying Research Center provides the tools you need today to…

The words in a language or language variety are often rank ordered in lists that are meant to reflect the relative importance of those words to language users and learners of a language. This rank ordering is done on the basis of the relative prevalence of words in a corpus. Lexical prevalence is often operationalized as measures of frequency,…

Beginning abruptly in the second half of the Spring 2020 semester at Purdue University, we modified our teaching approach in Introductory Soil Science and Forest Soils courses (AGRY 255/270) with a combined annual enrollment of [approximately]370 students to cope with the COVID-19 pandemic. In that semester, we went to entirely virtual lecture,…

For schools to successfully deliver the computer studies curriculum, they should have, among other things, qualified teachers and computer laboratories. This study investigated the availability of qualified computer studies teachers and computer laboratories in public secondary schools in Lusaka City, Zambia. A mixed-methods approach was employed…

Not only children but also adults now spend much more time in front of the screen (computers, laptops, tablets, phones, TVs, Play Station, other game consoles, etc.) for various reasons: work, study, a lot of free time, communication, entertainment, information retrieval. The aim of this paper is to examine how the time spent in front of the…

As access to smartphones and emerging technologies has become ubiquitous in our daily lives and in language learning, technology-mediated social interaction has become common in teaching and assessing L2 speaking. The changing ecology of L2 spoken interaction provides language educators and testers with opportunities for renewed test design and…
