Introduction: Interrupted Time Series (ITS) studies may be used to assess the impact of an interruption, such as an intervention or exposure. The data from such studies are particularly amenable to visual display and, when clearly depicted, can readily show the short- and long-term impact of an interruption. Further, well-constructed graphs allow…

Despite a major increase in the range and number of software offerings now available to help researchers produce evidence syntheses, there is currently no generic tool for producing figures to display and explore the risk-of-bias assessments that routinely take place as part of systematic review. However, tools such as the R programming…

An individual harmonic wave (i.e., having a single frequency and wavelength over all time and space) traveling in a loss-free medium has a single constant speed, which is equal to the magnitude of the phase velocity of the wave. However, when a set of different harmonic waves are traveling in the same direction, they interfere to form wave…

Among the most difficult aspects of building visual literacy is creating awareness of manipulation, a task made continuously harder by the prevalence of 'Photoshopped' or digitally altered photos through fake news or our everyday usage of photo editing apps. So how are educators to build awareness of visual literacy when manipulation has become…

This paper presents the R Analyzer for Large-Scale Assessments (RALSA), a newly developed R package for analyzing data from studies using complex sampling and assessment designs. Such studies are, for example, the IEA's Trends in International Mathematics and Science Study and the OECD's Programme for International Student Assessment. The package…

School curricula as well as scientific literature emphasize the need of understanding how children navigate with maps. To date, however, there is no empirically validated assessment tool for analyzing navigational map reading competencies that can be used in map-based navigation tasks in the real-world. This paper fills this gap by presenting…

Live cell imaging is a standard technique in experimental biology that enables the observation of isolated cells and tissue slices in real time and the testing of cellular responses to changes in buffer composition. However, most live cell imaging devices require the use of dedicated microscopes and/or specialised stage adaptors, and come at a…

This article reports on the design and implementation of a didactic sequence in the frame of a design-based research study. The research aim is to test the hypothesis that affordances of dynamic geometry may support students' awareness of logical relationships between geometrical properties of constructed figures. We elaborate on the task design…

Manual composition of tasks and exams is a challenging and time-consuming task. Especially when exams are taken remotely without the personal monitoring by examiners, most exams can easily lose their integrity with the use of previously done exercises or student communication. This research introduces an approach that incorporates the principles…

No solution can ultimately eliminate cheating in online courses. However, universities reserve funding for authentication systems to minimize the threat of cheating in online courses. Most higher education institutions use a combination of authentication methods to secure systems against impersonation attacks during online examinations.…

There has been a great deal written about ChatGPT since its launch in late 2022. Many news stories specifically address the impact of ChatGPT on education. However, there has been little research showing what K-12 teachers are thinking about and doing with ChatGPT. This research article helps to fill that gap. A survey of Missouri teachers was…

There is currently little research on the use of podcasting as a learning tool in the tertiary-level foreign language classroom. Here we attempt to partly fill that gap through a multiple case study of three university teachers who use this technology in their courses in Spanish as a foreign language. We obtained data for analysis primarily in two…

Although we are witnessing the accelerated development of computer science, and the opening of new fields of study, compiler construction is still a very important field that is taught at most world universities. Because of a large number of algorithms and complex theoretical constructions, these topics represent a difficult and complex domain for…

Emerging technologies present new possibilities for schools, but also present ethical issues for designers. Ethical issues arising from the design, accessibility, adoption, and implementation of emerging technologies in schools are intertwined with existing power dynamics, hierarchies, and decision-making norms that perpetuate entrenched…

This work investigates a cross-organizational technology-focused Community of Practice, namely Azure for Education, which supports educational organizations as they learn and implement Microsoft Azure platform technologies to solve business challenges in an environment of rapid technology innovation and evolution. While most research on…
