Background: Automatically graded programming assignments provide instant feedback to students and significantly reduce manual grading time for instructors. However, creating comprehensive suites of test cases for programming problems within automatic graders can be time-consuming and complex. The effort needed to define test suites may deter some…

The quality of interprofessional collaboration is a key determinant of the success and effectiveness of integrative care for children with multiple and complex needs. This study reports on the development and first psychometric evaluation of a questionnaire that assesses professionals' perceptions of interprofessional collaboration for child…

Since 2018, colleagues from two research centers at Dublin City University have been collaborating to develop a measurement scale to assess individuals' ability to identify workplace bullying. Having agreed on an operational definition of the construct, an item pool of 26 workplace bullying scenarios, that is, short descriptions of…

This paper describes the development and validation of an instrument to assess how students deal with emotionally challenging classroom situations (the DECCS Questionnaire). The questionnaire is based on a vignette with one learning and one performance situation in a classroom, and is intended for students in grades 4 to 7. On a sample of N = 639…

Background: One area that has been dramatically changed by artificial intelligence (AI) is educational environments. Chatbots, Recommender Systems, Adaptive Learning Systems and Large Language Models have been emerging as practical tools for facilitating learning. However, using such tools appropriately is challenging. In this regard, the…

This paper reports how I addressed the issue of extensive missing values in my PhD study, "Digital Competencies of High School Mathematics Teachers". I collected data using an online survey. Several methods exist to address the issue of missing values. I utilised multiple imputation (MI) as it provides more accurate results. The mean…

Universal screening of students is increasing as programs are implemented for improving social emotional learning (SEL) skills. Assessments used to conduct SEL screenings focus on social emotional strengths; however, such assessments can provide a broader characterization of students' wellbeing by concurrently screening for emotional behavior…

The purpose of the present study is to provide empirical evidence on the adaptation of the mathematics-related beliefs questionnaire (MRBQ) supplemented by info-communication technology-related items. Besides, we also investigate the relationship between their beliefs about mathematics and their ability in problem-solving mathematics. 234 grade…

Background/Context: Confirmatory factor analysis (CFA) model is a commonly adopted framework to estimate and test a measurement model. Once a well-fitting final CFA model is selected, the selected model may be used to test structural relationships of the latent constructs with other variables, to construct a test with desired reliability and…

GenAI's advanced natural language processing capabilities will revolutionize numerous areas, ranging from a paradigm shift in education to the economy. Along with the positive aspects of GenAI, ethical and social risks are also one of the negative aspects that attract attention in the literature. The purpose of this study is to test the role of…

This study aimed to develop a valid and reliable scale for determining teachers' needs to increase their efficiency in professional practice. The stages of creating an item pool, consulting expert opinions, pilot testing, and conducting validity and reliability analyses were followed. Initially, a 46-item pool was created based on a literature…

Objective: The psychometric properties of a measure of social determinants of health for college students entitled, The LIFESCREEN-C was developed. Participants: A sample of 226 college students completing an online survey during the 2018-2019 academic year. Methods: Tetrachoric correlations were used to confirm a three factor model. Results:…

While methodologies are often presented as standardised procedures which, under specified conditions, should lead to the same conclusions, this case study presents the complex and deeply personal process of research (Addey and Piattoeva 2022). We analyse our application of network ethnography -- an approach presented by Ball (2016) -- to the study…

Through creative thinking, it is possible to acquire new attitudes and a view of the world, not only of mathematics but from several sides (Kamp, 2016). Creativity in mathematics can be defined as a process based on sensitivity to problems, deficiencies, gaps in knowledge and sensitivity to identifying missing elements, revealing difficulties in…

This study engages in a rigorous process to develop an instrument, College Students' Financial Stress (CSFS). This instrument aims to assess college students' generalized financial stress, or financial unsafety, to provide administrators with a tool to gauge students' mental well-being and financial experiences in higher education. Accurately…
