Nearly one in three adolescents in our country experience stress or anxiety to the extent that it negatively effects their ability to cope with daily life demands. However, educators are not well prepared to support students who have anxiety-related issues. One approach for supporting adolescents with anxiety-related issues involves the use of…

A modern cybernetic potentiostat plays a significant role in realizing various electrochemical measurements. This technology report describes a general-purpose, scalable, handheld (10 cm[superscript 2]), yet affordable hardware-software framework for a potentiostat, galvanostat, and electrochemical impedance spectrometer with high capabilities:(1)…

Water pollution has been one of the major issues of the present time. It is essential to educate students regarding this issue and its possible solutions. In this article, a demonstration of a typical adsorption-based water cleaning process is presented. The removal of methylene blue (MB) and detergent from an aqueous solution is demonstrated…

Passive data from a tracking application (or "meter") installed on participants' devices to register the URLs visited have great potential for studying people's online activities. However, given privacy concerns, obtaining cooperation installing a meter can be difficult and lead to selection bias. Therefore, in this article, we address…

Technically simple and extremely cheap setups for colorimetric and fluorimetric analyses using a smartphone camera are presented. Laboratory activities on digital colorimetric and fluorimetric analyses for students of secondary and higher educational institutions are proposed, namely, photocolorimetric determination of acetylsalicylic acid in…

Can web-based interactive student response systems (SRSs) improve student performance in large introductory international relations courses? Does switching from first-generation clicker-based SRSs to second-generation web-based SRSs impact student learning? To answer these questions, we draw data from multiple offerings of Introduction to…

Various experiments on vibrating gas columns and on frequency measurements with glasses and pipes have been presented in recent years in the "iPhysicsLabs" column. The determination of the sound velocity in different gases by measuring the sound running time has also already been proposed in an earlier paper. This article now adds…

The aim of this study is to examine the frequency rate of FOMO (Fear of Missing Out) in both male and female students under some variables. Social media platforms which became an inseparable part of daily life have caused individuals to spend more time in the virtual world. From Sports Sciences, a total of 465 students (274 males and 191 females)…

The French National Cohort of Children Study ("Etude Longitudinale Française depuis l'Enfance"--ELFE) tested the literacy and numeracy skills of 4- to 5-year-old typically developing children in the second year of "école maternelle." Tasks were administered by more than 4,000 teachers at schools across France. One of the…

Implementing smartphones with their internal sensors into physics experiments represents a modern, attractive, and authentic approach to improve students' conceptual understanding of physics. In such experiments, smartphones often serve as objects with physical properties and as digital measurement devices to record, display, and analyze…

The aim of this study is to reveal the relationship between Turkish teaching and e-learning, m-learning and u-learning in the program dimension. The research was carried out according to the interpretative paradigm. In this study, which was designed according to the qualitative research method, document analysis was used as a data collection…

In education, we have noticed a significant gap between the ability of students to program in an educational visual programming environment and the ability to write code in a professional programming environment. The aim of our research was to verify the methodology of transition from visual programming of mobile applications in MIT App Inventor 2…

Astrophotography has been responsible for the discovery of planets, solar systems, stars, and several other celestial objects, which directly helps with expanding our knowledge about the universe and creating scientific models for nature. Practical techniques have been extensively described, including Covington, who has published an extensive…

The problem of rote-based learning in mathematics is well documented. Mobile technology can provide a potential solution, especially when application (app) design is based on sound pedagogical principles and gamification elements. However, an inventory of available mobile apps for mathematics reveals that many of the available apps are guided by a…

Communication privacy is constantly under threat from Nation State Adversaries (NSA). This has led many platforms, such as Facebook and Apple, to implement secure conversation cryptographic protocols in their messaging applications. However, many of the protocols do not provide provable security and do not provide other security guarantees about…
