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:…

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…

The rate of the sonochemiluminescence reaction of luminol in alkaline medium can be increased in the presence of carbon tetrachloride, chloroform, and bromoform. The presence of the latter activators enhances the light emission, to allow studying the kinetics of this reaction in a 4-h laboratory session using a mobile phone camera as a detector…

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…

Faculty at all types of colleges and universities struggle with how smartphone use may enhance or diminish their pedagogy, in part because evidence-based data is lacking for most types of classrooms. Thus, we conducted a thorough investigation in an introductory biology lab course to determine how smartphones affected myriad aspects of student…

Front camera data from tablets used in educational settings offer valuable clues to student behavior, attention, and affective state. Due to the camera's angle of view, the face of the student is partially occluded and skewed. This hinders the ability of experts to adequately capture the learning process and student states. In this paper, we…

We evaluated an emerging smartphone application, iNaturalist, to increase taxonomic identification and engage first-year undergraduate biology majors in outdoor laboratories of aquatic ecosystems (stream and lake ecology) and terrestrial ecosystems (tree and leaf litter ecology). Labs involved identifying organisms using both standard field guides…

With smartphone saturation at 100% among Japanese university students, educators are developing new and innovative ways to bring them to the forefront of learning, ensuring students are as engaged with their technology in their formal learning as they are with their informal learning. Smartphones of today are small, portable, have high spec…

Low cost, open-source analytical instrumentation has the potential to increase educational outcomes for students and enable large-scale citizen science projects. Many of these instruments rely on smartphones to collect the data, mainly because they can effectively leverage a dramatic price-to-performance ratio of the optical sensors. However,…

We designed a hands-on laboratory exercise to demonstrate why injecting an aqueous polymer solution into an oil reservoir (commonly known as "polymer flooding") enhances oil production. Students are split into three groups of two to three. Each group is assigned to a packed Hele-Shaw cell pre-saturated with oil, our laboratory model of…

In this study, the participants learned English as a foreign language (EFL) in the classroom and then worked on five learning tasks to apply their newly learned knowledge to unfamiliar environments. The participants took photos of people, objects, situations or scenarios and described them in detail using a mobile learning system. Familiarization…

With the advancement of digital technology, software and applications are overwhelmingly accessible to teachers and students. Digital designs for teaching and learning are highly encouraged by scholars as they prepare students of today for the demands of the future workforce. Thus, many educators use available social networks for their classrooms.…

Sexting is defined as sending/posting/sharing sexually explicit messages or nude/semi-nude images via electronic communication. Purpose: The purpose of this study was to assess and determine relationships of sexting behavioral intentions, sexting behaviors, and sexting content among selected Southern undergraduate students. Methods: Survey…

This study aimed to get ideas formed by undergraduate foreign language students about the applicability, advantages and disadvantages of "selfie@ssessment", which can be regarded as an alternative form of self-assessment utilizing modern mobile phone technologies and the available Internet facilities. Underpinning this study of…

A Ubiquitous Learning Log (ULL) is defined as a digital record of what a learner has learned in daily life using ubiquitous computing technologies. In this paper, a project which developed a system called SCROLL (System for Capturing and Reusing Of Learning Log) is presented. The aim of developing SCROLL is to help learners record, organize,…
