Proper waste management, aimed at making cities inclusive, safe, resilient, and sustainable, has been one of the goals of the 2030 Agenda for Sustainable Development. This, in turn, contributes to quality education and environmental justice. Thus, this study examined e-waste management practices in selected public secondary schools in the…

The semiconductor industry offers ample employment opportunities for chemical engineers. The CHIPS Act prioritizes workforce training as a key contributor to the success and growth of semiconductor manufacturing. UF ChE teaches semiconductor processing lab modules to both undergraduate and graduate students. At the graduate level UF ChE offers…

Contributions: This article presents the results from a teaching innovation project based on the creation of educational videos by students and their assessment through blind peer review in the context of an electric circuit course. This article also analyses the activity's impact on learning outcomes by comparing the results of participating…

Several studies suggest that children's learning and engagement with the content of play activities is affected by the ways parents and children interact. In particular, when parents are overly directive and set more goals during play with their children, their children tend to play less or are less engaged by subsequent challenges with the…

Experiments involving RC circuits are an integral part of introductory physics courses. Previous articles using RC circuits describe determining the charge on a Van de Graaff generator, measuring currents and voltages in a charging RC circuit using a multimeter or an Arduino, measuring the decay constants of complex RC circuits, and using the…

Electricity has shaped modern civilization in a way few other discoveries have. Nonetheless, few students successfully develop a basic understanding of voltage, current, and resistance or their mutual relationship in simple DC circuits. Despite teachers' best efforts in the classroom, so-called "alternative conceptions" often prevail…

In this study, we propose a novel and direct method of determining the focal length of a converging or diverging lens using a smartphone. The standard optical sensor used in modern smartphone cameras is an active-pixel sensor called the complementary metal-oxide-semiconductor (CMOS). The CMOS is covered by an assembly of five to seven camera…

Science education reforms advocate modeling as a core practice in which "analogy" is a significant form and "analogical modeling" is a creative process for scientific explanation and discovery. This study adopts the self-generated analogical modeling approach involving electricity, which considers all the modeling subprocesses…

Retrospective alcohol use data are prone to recall bias, a limitation that could be addressed with real-time ecological momentary assessment (EMA) tools. We aimed to (1) introduce a simple (single-click) EMA methodology for collecting real-time alcohol use data, and (2) investigate the EMA methodology's performance relative to established alcohol…

This exploratory study compares how young people (ages 15-16) learn circuitry concepts and layout design principles important to electrical engineering using one of two educational circuitry toolkits: paper circuits and traditional solderless breadboards. Paper-based prototyping kits are representative of a trend that incorporates new materials…

Contribution: The ability to design circuit layouts is a critical component of circuit design. This article presents an approach wherein layout-based design projects can be integrated into the traditional digital integrated circuit (IC) curriculum targeted at large classes and addresses the relevant challenges. Background: Most circuit design…

E-textiles provide an interesting field of research as they "blend traditional craft with modern science" (Peppler, 2016) and help learners "broaden their own perceptions of computing" (Searle et al., 2016). Despite the promising findings by primarily long-term interventions structured around e-textiles, educational curriculum…

Background: Electricity is a central concept in science curricula at all levels of education. Nevertheless, its invisible nature makes the concepts associated with it very difficult for students. Moreover, students have many alternative conceptions about concepts related to electrical circuits. This study aims to know the effect of a STEM…

In introductory electric circuits in middle school, students often carry strongly held alternative conceptions. Common to many of these is an idea of electric current as some kind of substance that originates from the battery and moves toward electronic components. Learners often argue that current influences those one by one as they are…

Objective: The present study evaluated the effects of nicotine concentration (0-10 mg/ml) and flavor (gummy bear vs unflavored) on the subjective experiences of vaporized nicotine in young adult low-dose nicotine (3 mg/ml) ECIG users. Participants: Eight young adult ECIG users were recruited. Methods: A single blinded crossover study was used.…
