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…

Light rays refract when passing through pockets of transparent fluids with different indices of refraction such as ordinary air pockets of varying temperature. This phenomenon makes night stars twinkle, distorts views above hot asphalt roads and hot barbeque grills, and provides an opportunity for visualizing the normally invisible movement of…

Using transformative experience theory as a framework, we investigate the potential of utilizing mobile technology and social media to foster deep-level engagement in the form of connections between in-school and out-of-school experience. A ninth-grade Earth science teacher instructed students to take pictures with their mobile devices when they…

To promote the integration of aesthetic education into chemistry education, this study designed activities to photograph precipitation reaction experiments with a smartphone, thereby combining experimental inquiry with artistic creation across disciplines. These activities were divided into (i) perceiving, (ii) appreciating, (iii) exploring, and…

Providing instant visual feedback, thermal imaging cameras are becoming more and more popular tools not only in industrial applications, but also in physics education. Continuously decreasing prices, modules compatible with smart portable devices, and intuitive operation make thermal measurements available for schools and attractive for students.…

This study aims to clarify the effect of the difference of visual stimuli in Photo Sharing websites (Instagram) on cognitive achievement for secondary education students in computer and information technology curriculum through the answer of the following question: What is the effect different visual stimuli in PSW (Instagram) on the cognitive…

The difficulties students have in blending mathematics and physics are here analyzed, by focusing on the issue of a convergent series. We present an experimental and a theoretical analysis of some phenomena which can be investigated employing series, as the bouncing marble and Zeno's paradox of Achilles and the turtle. Measurements were carried…

Cellphones are considered a convergent technology since their use goes beyond making a simple phone call, they are smart phones used as technological devices that have a series of applications as well as Internet connection. The use and appropriation of cellphones, consequently, require a series of learning and competence that is generated which…

Notions of place-making assume that individuals and groups of people have legitimate 'rights to the city.' This paper unsettles these notions to incorporate the politically and legally tenuous relationships African-American and Immigrant youth have to their cities. We describe a community-based digital STEAM curriculum called Mobile City Science…

In this article, we introduce and analyze learning experiences made possible by a teaching framework that we have developed and call "digital spatial story lines" (DSSLs). DSSLs offer a novel approach to learning on the move by engaging learners with related conceptual practices of archival curation, digital mapping, and the production…

Teens in high school who have or are at-risk of dropping out of school confront a number of educational challenges. One of these challenges is the restricted mobility students face in school. Mobile media offers the potential to engage with art curricula inside or outside of the classroom. It also offers new ways of thinking about the role of…
