Mobile phone interventions are evidence-based methods for preventing obesity among Latino adults and school-aged children; however, few such interventions exist to improve the obesogenic behaviors of children in the developmentally critical preschool years (ages 2-5). Focusing on this age group is important since over one-quarter of 2- to…

The aim of this study is to examine the relationship between university students' digital burnout levels and their perceived stress levels. The population of the research consists of students studying at Inönü University, Malatya, in the spring semester of the 2020-2021 academic year. The data were collected online. The sample included 925…

We propose a laboratory experiment on the quantitative study of the normal dispersion of light. A triangular isosceles prism made of flint glass TF3 is used as the object of study, and we describe a simple and affordable device for observing and photographing the dispersion spectrum on a smartphone. A possibility of the quantitative investigation…

Wearable devices are a popular class of portable ubiquitous technology. These devices are available in a variety of forms, ranging from smart glasses to smart rings. The fact that smart wearable devices are attached to the body makes them particularly suitable to be integrated into people's daily lives. Thus, we propose that wearables can be…

The present study aimed at investigating nomophobia prevalence, thus, recurrence of anxiety without a smartphone, with preservice teachers in the Colleges of Education, Ghana. An actual sample of 345 preservice teachers responded to a 20-item questionnaire on nomophobia (NMP-Q). A one-way MANOVA between different groups statistics was applied in…

In recent years, do-it-yourself microcontrollers and sensors have gained increased attention as measurement devices for physics teaching (see, for example, Refs. 1-5). This is not surprising, since Arduinos are relatively cheap and ubiquitous, the code base and design are open source, and there is a wide variety of sensors available. Arduinos can…

A smartphone magnetometer is used to record the magnetic field of a freely falling point dipole magnet. The recorded magnetic field vs. time data are analyzed in accordance with the spatial dependence of the magnetic field to calculate the acceleration due to gravity g. The experiment gives local g to be 9.79 ± 1.9% m/s[superscript 2].

Objective: To estimate the incidence of mobile device use among street-crossing pedestrians and explore differences by sex and intersection type at a large public South-eastern university in the United States. Participants: All instances of campus pedestrians crossing the street during the observation period (N ¼ 4,878). Methods: Video recordings…

Past studies of texting interventions designed to promote college student persistence have given little attention to assessing both the fixed and variable costs of such initiatives. In addition, they typically have not assessed costs relative to the desired outcome(s). In this case study, we assessed the costs of implementing a text messaging…

Children's fine motor skills are linked not only to drawing ability but also to cognitive, social-emotional, self-regulatory, and academic development Suggate et al. "Journal of Research in Reading," 41(1), 1-19 (2018), Benedetti et al. (2014), Liew et al. "Early Education & Development," 22(4), 549-573 (2011), Liew (2012)…

In digital play, social interactions have aroused much debate among early childhood stakeholders, particularly in the areas of young children's social learning and their domains of development. The main concern of early childhood educators is the limits of children's social interactions occurring in digital play. This study used a four-week…

This short paper describes an early look at a project aimed at aiding students to understand various viewpoints through the advocacy of a museum visit. It aims to both improve historical reasoning and allow for more open-mindedness. This is done by combining a process of citizen curation with the use of de-polarization techniques. [For the…

Students' cellphone use has been related to poorer learning, possibly due to greater distraction. This study investigated whether cellphone-related anxiety, addiction, and disconnection were related to distraction and learning as well as how practical educational policies could minimize negative effects. Participants (N = 218) watched a video…

Background: Mobile technology has the potential to assist adults with intellectual disabilities to initiate and maintain social connections in important areas of their lives, such as family, friends and work/volunteering. Method: The present study investigated how specific aspects of mobile device/app use are associated with the social inclusion…

This study contributes to research in the field of phonology of sign languages, focusing on the occurrence of assimilation of signs. The objective of the study is to analyze assimilation cases present in the text genre "joke" in Brazilian Sign Language (Libras), as well as influences of the immediate context on their occurrence. We…
