The first of the two postulates of relativity states that the laws of physics are the same in all inertial reference frames. Often it is assumed that the postulates are mainly concerned with objects moving at a significant fraction of the speed of light. However, the postulates are applicable at all speeds from a snail to a photon. To practically…

The development of Android-based mathematics learning media aligns with the advancements of Industrial Era 5.0. This study aims to develop an Android-based mathematics learning media on geometry that is contextually relevant to tourist destinations. The methodology employed was the ADDIE approach, comprising five phases: analysis, design,…

To address disparity issues in STEM fields, this study implemented a culturally relevant, hands-on learning program tailored for African American high school students from low-income areas in America's Deep South. The program included a one-month summer academy followed by a four-month collaborative app design project using MIT App Inventor. A…

Low-powered mobile devices such as Raspberry Pis and tablets can be used as microservers to implement offline Learning Management Systems (LMS). Despite their potential, especially for low-income countries, such as Tanzania, no research is available detailing the affordances of these devices for supporting LMS features. This study investigated the…

Accurate assessment of saliva sampling time is essential for studies that collect cortisol sample in ambulatory settings. This study examined the sampling time assessed by user-submitted photos via a mobile application (ZEMI) compared with MEMSCaps™. Intra-class correlation coefficient (ICC) of the time differences between when the 16 adolescents…

Mobile technology is one of the most important approaches to facilitating vocabulary learning. However, despite an increasing use of mobile devices for this purpose, there is currently no dedicated evaluation framework to examine whether the vocabulary-learning applications on the market are well designed. Building on prior research from the…

Mindfulness apps have shown promise to reduce stress and improve well-being among college students however the mechanisms of these beneficial effects are less clear.

Purpose: Technology, including educational applications (apps), is commonly used in schools by teachers and speech-language pathologists. Nonetheless, very little research has examined the efficacy of these apps for student learning or how to choose appropriate apps for instruction. Several previous rubrics to evaluate the instructional quality of…

Digital portfolios offer opportunities for reflection and collaboration in teacher education. However, the affordances of mobile devices have scarcely been explored in this context. A mixed-methods study was conducted wherein 44 student teachers collaboratively used a mobile portfolio app for reflection with peer students and mentors during…

Recent advancements in geospatial technologies enable geography students to explore outdoor phenomena independently, without teacher guidance. Several authors argue that smartphone apps can effectively replace the teacher in excursions, addressing challenges such as teachers' limited availability. However, empirical research comparing the actual…

This study compares museum-related knowledge, museum learning experiences and cognitive load based on task types presented via a mobile application during a museum virtual tour. The study involved three experiments, each examining the effects of different task types. In the first experiment, tasks varied by difficulty (easy vs. difficult), in the…

Despite the pervasive use of wireless technology in today's society, people with intellectual and developmental disabilities (IDD) have limited access to technology. Technology is underutilized by this population for a variety of reasons including cost-related barriers and cognitive inaccessibility of devices and software applications. The lack of…
