This study examined the effects of a mobile camera versus a stationary camera on scores for Rubrics 6-9 of the Elementary Education edTPA Task 2. Scores on these rubrics are primarily based on video evidence for a positive classroom environment, engaging students in learning, deepening student learning, and subject-specific pedagogy. Over two…

Families commonly document their outings by capturing their experiences through digital photographs and videos. However, little is known about the ways in which families engage their personal mobile devices to document educational family outings and how they subsequently talk about the digital artifacts that captured their informal learning…

We report here a successful adaptation of lab videos used during remote instruction to a kinetics experiment reported in this Journal in 2007. In the in-person lab, students now record their rate data on their cell phone cameras and then collect their data from the videos for their postlab reports; previously, they acquired the data in real time…

In this column, I discuss a soundscape composition activity that I implemented with primary/elementary music classes. During this activity, students used the iPad app, iMovie, to record, organize and edit sound to accompany photos of artworks that they had created. Overall, I found iMovie to be a useful app for music composition with general music…

Humans are arguably the most interesting subjects in computer vision. Modeling human 3D geometry from images captured by highly sophisticated production level cameras (10-100 cameras with precise calibration) enable a number of applications, e.g. telepresence, virtual try-on, motion analysis, etc. Despite its production level quality, the…

Limited literacy has a large impact on the U.S. population; about half of adults lack sufficient literacy proficiency. However, not all populations are impacted equally, as there is a significant comorbidity between low literacy and mental illness. The authors have found that smartphones can offer mental health patients with low literacy numerous…

Early adolescents are frequent users of online communication tools (OCTs). Yet, we have limited knowledge about how OCTs influence this population and their friendships. We sought opinions of 938 Austrian early adolescents on the role of OCTs for their friendships via a questionnaire and 207 focus groups. Thematic analysis was used to analyze the…

Despite the fundamental importance of plants to our very survival, student interest in plant biology is in decline as technology draws us further away from nature. Here we introduce "Plant Tracer" (http://www.planttracer.com), a Matlab-based program, which can quantify time-lapse videos of plant movement. We demonstrate that Plant Tracer…

Your body is not a point particle. The nature and direction of the forces counteracting gravity influence your experience of uniform rectilinear motion--as does your own orientation in relation to the force of gravity. Sensors in smartphones or other devices can capture these forces, and help establish a connection between the personal experience…

This research aims to develop a falling chain experiment apparatus using kitchen scales and digital cameras (smartphones). Digital cameras were used to observe and record changes in the mass of falling chains measured using kitchen scales. Video recordings from observations of falling chain masses were analysed using Tracker 5.1.1 software. The…

In this article we present simple and low-cost experiments about the polarization of light. We use an LCD monitor or an RGB LED light bulb with a Polaroid as a source of polarized radiation, a polarizer sheet as an analyzer, and a smartphone camera to measure light intensities. Thus, using a digital camera to acquire videos students can explore in…

Previous research suggests that students can use exploratory talk to support their thinking and learning. However, students' own perspectives on such talk, and whether/how they value it, are rarely sought. Thirty 12-year-olds and their teacher used Talk Factory on an interactive whiteboard and iPads to support exploratory talk in English lessons…

Social networks integrate adolescent daily life by configuring modes of socialisation, negotiation and self-representation through different practices that operate as subjectivation resources and condition the gender experience. The objective of this study is to explore the production of selfies and videos among adolescents from Puebla (Mexico)…

This paper is inspired from a scene in the movie "Memento" (2000), where the eyeglass prescription for a myopic eye can be estimated since the virtual image of a distant wall seen through the lens and a nearby actor outside the view of the lens are located at the same distance. The estimate illustrates that there are times when the power…

How do prosocial sharing behaviours of preschool-aged children progress or diminish when interacting with mobile devices? Participants include five children (ages 3-4) within a preschool setting in Vancouver, British Columbia. Design-based research and video ethnography were used for qualitative and quantitative data collection and analysis. Data…
