This study aimed to assess the agreement in physical activity (PA) estimates from Garmin Vivofit Jr. 3 (VFJ 3) and Fitbit Ace 3 (Ace 3) with a research-grade accelerometer (wGT3X-BT) in children under free-living conditions. Twenty-five children (Girls: 56%, Age: 10.1 ± 2.5 years, BMI: 17.1 ± 2.4 kg/m2) performed daily activities for 7 consecutive…

As technology becomes ubiquitous in the homes of many families, children learn to incorporate touchscreen devices into their everyday activities. The present study explored young children's role in shaping their gaming experience to maintain social interactivity. Twenty-nine children at 2.5 years old in the U.S. played a non-educational game on a…

Enabling smartphones to be foldable provides an effective approach to achieving both portability and large screens. Notably, switches between closed and open states in using foldable smartphones are accompanied by icon remapping, which can decrease smartphone usability if it fails to match usage expectations. This study conducted two experiments…

This study explores the feasibility of forming detailed inferences about museum visitor behavior based on analysis of data collected via "Dr. Discovery"--a mobile question-and-answer app. We analyzed 5656 questions asked by 795 visitor groups recorded by Dr. Discovery across two museums in the American Southwest. Analysis of this data…

Background: Literacy is an important skill that is necessary for people--especially adolescents--to access electronic media, including mobile devices. The only way to develop competence in reading is by reading more. Young people who enjoy leisure reading are usually more successful readers. In this study, the authors did research into a group of…

Fear of missing out (FoMO) is the apprehensive feeling that others are engaging in rewarding activities. Because adolescence is a time in the lifespan when individuals are sensitive to social cues, FoMO may relate to engagement in risky activities and poor mental health. Sexting is a risky activity, where adolescents send and receive sexually…

Objective: To measure the interrater reliability of assessing the frequency of vegetable intake using mobile photos and descriptions. Design: Repeated measures design. Setting: A Midwestern university. Participants: Undergraduate students (N = 165). Measurable Outcome/Analysis: Number of times each of these vegetable subgroups were consumed daily:…

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…

The home literacy environment (HLE) plays an important role in children's early literacy learning. Texting programs are an increasing feature of family literacy interventions that support parent engagement in their children's learning. Unlike face-to-face interventions, texting programs can offer sustained parental support at low cost and large…

Linking survey and social media data has gained popularity. However, obtaining consent from respondents to link social media is a known challenge. Using data from a nationally representative survey of the U.K. this study investigated whether respondents' a) activity frequency, b) activity variety and c) technical skills with smartphones are…

While biosensing is becoming a popular tool among urban geographers to address the emotional experience of the urban environment, it is also posing significant challenges, as its application demands expertise on technology and human physiology that is not part of regular curricula in geography courses. Despite this, there is little exploration of…

The study examined the implementation of Regulation COG-RA and local school personal mobile device (PMD) guidelines, focusing on awareness, supportive practices, and changes in the school community. Using a mixed-methods approach, data were gathered from staff, student, and family surveys, as well as document reviews, with special attention to ten…

The current study examined why people take and delete photos with smartphone cameras, and participants' recollective experiences with saved and deleted photos. Two mixed-methods surveys asked undergraduates (Study 1) and an international online sample (Study 2) to review both recently taken and recently deleted photos from their smartphones' photo…

As handheld devices, such as tablets, become a common tool in schools, a critical and urgent question for the research community is to assess their potential impact on educational outcomes. Previous meta-analytic research has evidenced the "screen inferiority effect": Readers tend to understand texts slightly worse when reading on-screen…

During early adolescence children are increasingly using their smartphones not only throughout the day, but also before or even during the nighttime. Prior research has revealed that children's school performance might suffer because of late-night smartphone use. To gain a further understanding of the consequences of nighttime smartphone use on…
