Objective: To test the effectiveness of a text-message intervention to promote sleep hygiene to improve sleep in young adult college students. Participants: A convenience sample of undergraduate students from one Southwestern university (n = 96), 18-26 years old, recruited in August 2015. Methods: A 2-group pretest-posttest experimental design…

Digital learning and wireless connectivity have become so entrenched in schools that many educators now consider high-speed Internet access a requirement for effective teaching. Advocates aspire to equip every student in America with wireless access. But schools are finding that a substantial number of people have health concerns about the radio…

First-generation Chinese and Korean male immigrants in the United States are at high risk for tobacco use. This study pilot-tested a graphic, native-language text-messaging intervention to promote smoking cessation among these groups. First-generation Chinese and Korean male immigrant smokers (N = 71) were recruited from the Washington DC area.…

We built a low-cost and hand-held device to image and analyze microfluidic droplets mainly for educational/teaching purposes in laboratory settings of universities. The device was assembled based on a Raspberry Pi with a camera attached on the back and an LCD screen on the top. We evaluated the performance of this device to capture images and…

This paper reports on the measurement of a magnetic field due to the coil carrying current by using the magnetic sensor in a smartphone as an alternate to the relatively expensive magnetic sensor probe. The location of the magnetic sensor in the smartphone was known by mapping the value of the magnetic field due to the permanent magnetic bar so…

This book presents a mobile technology capacity building framework that offers academics, students, and practitioners involved in workplace education a deeper understanding of, and practical guidance on, how mobile technology can enhance professional learning. Approaching professional and workplace learning as a hybrid space in which work,…

This paper summarises findings from an initial study completed as the first phase of the Erasmus+ KA2 research project: Designing and Evaluating Innovative Mobile Pedagogies (DEIMP). The purpose of the scoping study was to inform the design and development of a multi-purpose mobile app that will support educators and pre-service teachers in…

Objective: Our objectives were to measure reporting differences between sexual behavior data from daily diary and retrospective estimates and to assess the utility of using smartphones to collect sexual behavior data from a college student population. Participants: Eighty-six participants (68 women, 18 men) completed the study. Methods: For…

The planets in our solar system are remarkable and captivating objects for beginning astronomers to study. While merely observing the planets is fairly easy, it can be difficult to capture the high-quality images beginners hope for. The methods used for deep-sky astrophotography are optimized for dim, fairly large objects using large apertures and…

Recently, infrared cameras have become available as smartphone accessories. Being less expensive than regular infrared cameras they are readily affordable for schools and many teachers may even privately own one due to their potential to visualize all kinds of thermal phenomena in physics teaching. Any science teacher who wants to use such a…

The understanding of the design of mobile phones is somewhat different from other devices and products. This is properly due to the limited design capacity of mobile phones which need to be maintained within a small screen. One aspect for consideration is the relationship between certain design elements and users' usage behavior and perception of…

The smartphone's ambient light sensor has been used in the literature to study different physical phenomena. For instance, Malus's law, which involves the polarized light, has been verified by using simultaneously the orientation and light sensors of a smartphone. The illuminance of point light sources has been characterized also using the light…

Within the literature, a respectful number of studies related to the use of assistive technologies for special education, resulting in an enormous agenda that encompasses various types of assistive technology applied across disabilities in different types of curricula. These disabilities include, but are not limited to: learning disabilities,…

This study aimed to assess college of education students' learning attitude and academic performance in using m-learning during the COVID-19 pandemic. The study employed a pre-test and post-test experimental research design with 50 students from the College of Education, Ikere Ekiti, Nigeria. Two research instruments were used to collect data from…

The aim of this study was to assess the impact of the integration of tablets and a mobile application for fitness development into a PE lesson in primary education, in schools that did not apply a 'one tablet per child' policy, on students' intrinsic motivation for the PE lesson. Four 5th grade and four 6th grade classes (145 students aged…
