Resonance is an ubiquitous phenomenon present in many systems. In particular, air resonance in cavities was studied by Hermann von Helmholtz in the 1850s. Originally used as acoustic filters, Helmholtz resonators are rigid-wall cavities that reverberate at given fixed frequencies. An adjustable type of resonator is the so-called "universal…

Smartphones have evolved into all-purpose computing machines with exceptional capabilities. They are becoming increasingly powerful, with modern audio "codec" (coder/decoder) chips that provide recorded audio of high quality. Smartphone developers now offer many sound applications (apps) using both the devices' built-in microphone and…

We studied the impact of different layouts for rank order questions on respondent effort, data quality, and substantive results among PC and smartphone respondents, in an experiment in an opt-in online panel in Spain, using an order-by-click design. We experimentally varied the device, the number of columns, and, for smartphone respondents, the…

This paper describes the development of a mobile application to engage students in active learning in analytical chemistry. Colorimetry is a topic in analytical chemistry that can effectively be learned through the use of mobile devices to perform colorimetric measurement in the real-life environment. Previous attempts in the development of…

For teachers to utilize Mobile Assisted Language Learning (MALL) resources, they must consider how to balance implementation with their available resources. As it is no longer the case that programming is required to create one's own MALL resources, teachers could benefit from a framework that helps them to match their resources and pedagogical…

The purpose of this study is to examine the use of augmented reality technology in the field of sports science and to develop a sample educational software including musculoskeletal system and warm-up exercises. Each stage of the software development process is explained in detail. The basis of augmented reality technology is the simultaneous…

Facebook groups (FGs) have been widely used by teachers/educators. However, the type of educational FGs they value most, and the reasons for their choices, are less clear. This paper examines the perspectives of 440 participants (86% mathematics teachers and 14% mathematics teacher educators) on their educational FGs. It identifies the types of…

Although socioeconomic disparities in college enrollment have declined, gaps in college completion persist by income and geography. We investigate a text messaging campaign in West Virginia, which addressed informational barriers and behavioral obstacles to college persistence by providing college students with simplified information,…

As one of the most popular Online Student Response Systems (OSRSs), "Socrative" is defined as a web-based platform that can be accessed using any browser that is connected to the Internet (Mork, 2014). In an attempt to guide EFL teachers on their journey towards transforming their traditional paper-based formative assessment into using…

Facile visualization of biomolecules is an essential component of the undergraduate biochemistry curriculum. In the past, a number of tools have been used to display biomolecules. More recently, the advent of greater accessibility to virtual reality (VR) and augmented reality (AR) programs has created a new mechanism to visualize biomolecules.…

In the fields of information technology and information systems, faculty must consistently adjust curriculum to meet the demands of the field. However, a challenge they often face is understanding what should be covered, especially given the limited number of courses most universities are able to offer. This research explores the knowledge and…

We compared the acquisition of receptive labeling using stimuli delivered via tablet and via flashcards during discrete trial instruction in three preschoolers with Autism Spectrum Disorder. Using an adapted alternating treatments design, we compared the number of sessions required to meet a mastery criterion for receptively identifying stimuli…

The advance of pervasive technologies such as mobile technologies and various mobile devices has brought opportunities for educators to design and perform interactive learning activities and has also enabled educationalists to access the virtual learning environment anytime and anywhere without restrictions of time or place and without too much…

An increasing number of studies have addressed and proved the positive impact of classroom response systems (CRS) on learning performance in active learning environments but few focus on the parameters for the adoption and use of this technology in the classroom. This paper reviews research that has tested the parameters that influence the…

To promote the integration of aesthetic education into chemistry education, this study designed activities to photograph precipitation reaction experiments with a smartphone, thereby combining experimental inquiry with artistic creation across disciplines. These activities were divided into (i) perceiving, (ii) appreciating, (iii) exploring, and…
