Common over-the-counter medicines can be an exciting entry point for introducing students to the interesting chemistries that they encounter in their daily lives. In this inquiry-based activity, students are tasked with using a list of given supplies and information about four medications (Aspirin, Tums, Pepto-Bismol, and Tylenol) to design three…

It is crucial nowadays to predict in a fast and simple manner physical-chemical behaviors like, the size-dependent optical properties of gold nanospheres (Au NSs). The idea behind this experiment is trying to replace (as much as possible) robust and expensive microscopy techniques with UV-vis spectrophotometry and friendly simulations. Students…

The particle-in-a-box experiment is a well-known method used to teach quantum mechanics concepts in physical chemistry laboratories for undergraduates. The investigation involves measuring the wavelength at maximum absorbance ([lambda subscript max]) of electronic transitions in the UV-vis spectrum and linking it to the box length. As the…

In this article, we discuss the replication of a forgotten chemical instrument in the context of undergraduate chemistry education. Together with students, we have attempted to replicate an eighteenth century "eudiometrical" procedure. Eudiometry was the practice of measuring the "goodness" of the air by looking at the volume…

Challenge: While hands-on laboratory experiences are an important component of biomedical engineering curricula, many of the topics which would often benefit most from these experiences are often too time-, space-, and resource-intensive to incorporate into laboratory classes. One such topic is electrophysiology, where phenomena are hard to…

In the first decades of the twentieth century, amidst the emergence of experimental psychology, Latin American educators became pedagogical innovators and advocates of school reforms. They used the classroom as a laboratory to study children's intelligence and collect data that could potentially improve their education. This paper traces…

The COVID-19 pandemic disrupted community colleges and created a new context in which they were forced to operate. Faculty, especially those who normally taught in-person, were required to transition quickly to fully online classrooms. Drawing on semi-structured interviews conducted at the start of the pandemic with 17 students pursuing degree…

Contribution: A remote laboratory system for induction motors was developed in this study. By creating an original simulated induction motor, the structure of the motor can be observed, and the current and magnetic flux can be measured safely. Background: Electrical machinery has little appeal to young engineers. Such machinery deals with…

Purpose: Hands-on training in tissue engineering is often associated with specialized labs and expensive equipment, such as CO[subscript 2] incubators. To minimize the use of costly commercial incubators and provide a more vivid engineering experience in a biology lab, we present a hands-on project that introduces medium to large groups of…

Technological development, particularly in experimental, is now embedded in physics textbooks. Therefore, this study analyzed how the basic inquiry and the integrated science process skills in digital-related experiments are distributed within physics textbooks of South Korea, the United Kingdom, and Indonesia. A descriptive qualitative content…

This article describes the design, implementation, and evaluation of the gamification of laboratory activities in a General Chemistry course at the Federal University of Ceará in Brazil. In the gamified laboratory, seven experiments traditionally performed in the course were transformed into ten missions, incorporating game elements such as…

Research in physics education has revealed that students often have incomplete and incoherent ways to use the concept of photon. Most researchers in science education recommend photons to be taken in a realistic sense as existing entities of quantum objects. Furthermore, in science education literature it is often claimed that realistic stance to…

Understanding social interactions among students comprises a rich area of physics education research. Here we focus on the social interactions in introductory physics laboratories (labs). Most existing research in such contexts focuses on within-group social dynamics, however, we argue that interactions between different lab groups are just as…

The proliferation of remote laboratory instruction increased substantially during the recent global pandemic. Many physics departments implemented this rapid transition without the previous experience, time, and deliberation to optimize learning experiences for students. The present quasi-experimental, nonequivalent group design study examined…

Neutrinos are perhaps the least understood of the known denizens of the subatomic world. They have nearly no mass, interact only via the weak nuclear force and gravity, and, perhaps most surprising, the three known species of neutrinos can transform from one variant into another. This transformation, called neutrino oscillation, has been…
