The aim of this study is to determine the effect of computer-supported collaborative learning (CSCL) using GeoGebra software on 11th grade students' achievement in exponential and logarithmic functions. This study was carried out with quasi-experimental design consisting of a pre-test and a post-test with the experimental group and the control…

This paper reports on students' learning experience with a hybrid Augmented Reality (AR) and Virtual Reality (VR) app called the Kuching Heritage App (KHA). We investigated the effect of visualisations, time lapse (i.e., past to present), and the witnessing of historical changes on students' learning experience about cultural heritage. This pilot…

Online environments are an integral part of the lives of many young people. Surveys indicate that almost half of 10 to 15-year-olds in England and Wales spend three or more hours online on a typical school day (Office for National Statistics [ONS], 2021). Concern about the negative impact of the digital world on young people has increased in…

Novel forms of technology, like shared Augmented Reality (AR) holograms, can spur the discovery of new hypotheses about cognition and how it is embodied and distributed. These holograms have affordances for exploration, collaboration, and learning that have never been seen before. In the present study, we examine the multimodal ways that high…

The purpose of this study was to explore the experiences and motivational factors that influenced educational and career decisions of United States military veterans who transitioned out of the military and into an information technology (IT)-related career field. The study investigated the reasons veterans decided to pursue IT-related careers,…

Understanding youth relationships with nature--what nature is, where nature is located, and why nature is meaningful--is important for a range of contemporary issues, from promoting health and well-being to advancing a sustainable future. Relationships with nature are profoundly influenced by the lived experiences of youth, as they form social…

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…
