The first of the two postulates of relativity states that the laws of physics are the same in all inertial reference frames. Often it is assumed that the postulates are mainly concerned with objects moving at a significant fraction of the speed of light. However, the postulates are applicable at all speeds from a snail to a photon. To practically…

We describe an educational activity that can be completed with mobile media devices in order to understand the working principle of a pair of tuning forks, from the Historical Collection of Physics Instruments of the University of Palermo, and how they were used to explain acoustic interference and beats with the Lissajous optical method. This…

The oscillations of one mass "m" suspended between two different springs, assuming a friction force proportional to the velocity [minuscule], have been studied. For this purpose, an assembly for this system has been made. The movement of the mass is recorded with a smartphone and analysed with "Tracker." It is obtained that the…

Mobile app escape games are excellent tools to create an experiential learning process in online contexts. Through the act of solving puzzles to escape the rooms, students experience a process in which they need to discover new information and clues, adjust their strategies repeatedly, and become more aware of the way they learn. Their emotional…

The focus of this research was measuring the effect of Twitter use in the classroom on students' acceptance of technology using the TAM-3 model. This mixed methods study revealed a significant effect from students' use of Twitter in classroom assignments not only on increasing candidates' view of Twitter as being useful, easy to use, and relevant…

Logistic regression was used to examine the use of Autism Spectrum diagnostic categories from pre-COVID-19 in-person evaluations and COVID-19 telehealth evaluations at a specialist community mental health clinic. The diagnostic classification for children 0-5 (DC: 0-5) affords a wider range of diagnoses that allowed for inferences of clinician…

In this paper, we propose a simple yet generic and versatile method to measure the position of a moving body as a function of time. Apart from very basic equipment such as carts and wheels, only a laser pointer or a similar device and a smartphone are necessary. By attaching a source of light to a cart and video filming its movement on a…

In this paper we analysed the use of WhatsApp among first-year students at the University of Technology in the context of South Africa. Drawing on Deleuze and Guattari's Assemblage Theory, the study analysed postings on a WhatsApp group and secondary data using content analysis. The findings showed that first-year students used WhatsApp for…

Smartphones have many characteristics that make them attractive to adolescents. Recent work, however, has established a link between smartphone-related problems and self-esteem (self-worth) and social anxiety (fear of social relations). To date, little is known about the characteristics underpinning these relationships in combination. Driven by…

Students' problematic internet behaviour is often mentioned concept in the related literature. Even though the related literature concentrated on students' problematic internet behaviour from various perspectives among different sampling groups, most of the studies focused on adults than younger groups. Therefore, the current study focused on…

Design and computer graphics curricula for tertiary education include 3-D modeling skills. Students must learn to represent (complex) 3-D objects by means of parametric surfaces or polygonal meshes. Three-dimensional modeling may be a complex task, and students must be able to accrue a certain deal of experience in the field before passing the…

Clinical Question: In speech intervention via telepractice for preschool and school-age children with speech sound disorders (SSD), is treatment intensity similar to or different from that of traditional in-person therapy for optimal treatment results? Method: Systematic Review. Study Sources: PubMed, Education Resources Information Center (ERIC),…

Children with emotional disturbance have historically poor outcomes, including separate school environments, exclusion from school due to disciplinary actions, high dropout rates, poor employment outcomes, and incarceration. Therefore, it is imperative that children displaying early warning signs for risk of emotional disturbance receive effective…

A significant share of education and development research uses data collected by workers called "enumerators." It is well-documented that "enumerator effects"--or inconsistent practices between the individual people who administer measurement tools-- can be a key source of error in survey data collection. However, it is less…

Adult education staff have used varied approaches to help adult learners address their non-academic barriers to participation such as connecting learners to resources that can mediate those barriers. There is increasing interest in the potential of "nudging" through text messaging as an efficient and low-cost intervention to support…
