A straightforward experimental set-up, requiring a two-liter bottle, a ruler and a stopwatch, is used to provide data appropriate for modelling with Torricelli's Law in the simplest case, and a more sophisticated differential equation when losses are taken into account and a pipe extension is considered. With only an exit hole included in the…

Background: The adoption of virtual laboratories (VLs) has experienced a significant surge, catalysed by the global changes in the educational landscape, notably influenced by the COVID-19 pandemic. Originally supplementary to traditional in-person laboratory experiments, VLs swiftly transitioned into a primary source of hands-on laboratory…

Online video experiments are a promising educational technology tool for science laboratory classes. In order to find optimal instructional designs and scenarios for using online video experiments, we need to study learners' experiences. This work describes implementation of an online interactive video experiment at the undergraduate introductory…

Air pollution is one of our day's significant reasons for human health problems and affects every community throughout the world. Monitoring air pollution is a key aspect of raising awareness and pollution mitigation approaches followed by different nations. This paper targets to develop a low-cost Internet of things-based embedded system to…

The scope of this preliminary study revolves around investigating the effectiveness of experiential learning in upper-year science laboratory courses in a post-pandemic era. In this study we have explored two key questions: 1. Can experiential learning facilitate independent inquiry in an upper-year undergraduate laboratory in a post-pandemic era?…

During the COVID-19 pandemic and subsequent lockdown, both schools and universities faced significant challenges in moving teaching from an in-situ setting to a remote one, this included laboratory experiments. This paper presents an experiment developed to use a phone's in built pressure sensor, common to most smart phones. By using this sensor…

An integrated inorganic chemistry laboratory experience focusing on heterogeneous electrocatalysis with nickel (Ni)- and cobalt (Co)-based electrocatalysts is designed for upper-division, major-level chemistry students. In this laboratory, students will be guided through the fabrication of an indium tin oxide (ITO)-coated glass working electrode,…

The COVID-19 epidemic adversely impacted chemical engineering experiments(CEEs). Students underwent online learning, i.e., software simulation of the CEE course, instead of laboratory learning. A questionnaire survey revealed that students exhibited low enthusiasm for online learning, showing that online courses cannot ensure learning quality.…

The advantage of VLs lies in their capacity for simulating real-world lab experiences within a fully immersive digital environment, yet the uptake in rural schools in developing countries remains low. To understand this paradox, this study explores the perceptions of seven secondary school science teachers in a rural district in South Africa.…

There have been growing calls for inquiry, a practice-oriented way of engaging students in authentic scientific work, yet research has shown some challenges that might impede inquiry practices in educational settings. In this study, we proposed an approach that blends educational gaming with physical experiments. We developed an educational game,…

The article introduces a low-cost Arduino sensor into the Young's modulus determination laboratory for physics university students. A stainless steel ruler is used as a cantilever beam. Its free end attached a mass is slightly bent and released to make it oscillate as a simple harmonic motion. The Arduino sensor detects the moving mass's frequency…

This research will be carried out at the basic physics laboratory of the physics education study program, Muhammadiyah University of Makassar. The long-term goal of this research is to produce a prototype model of basic physics practicum based on the virtual android observatory to facilitate the ICT literacy skills of prospective physics teachers.…

As ongoing digitalization accelerates the execution of experiments and the documentation and storage of the corresponding data substantially, appropriate research data management (RDM) is a necessity to enable sustainable research at all. Consequently, a rethinking is currently taking place in academia. This process becomes visible by the…

The electrolysis of water to produce hydrogen is a critical step in many green chemistry processes. The key to the efficiency of water electrolysis is the synthesis of an appropriate electrocatalyst. Three-dimensional (3D) printing is an increasingly important part of many industrial processes. In this study, we propose an efficient laboratory…

Due to the COVID-19 pandemic, in the spring of 2020 many physics programs were forced to quickly transition all of their classes and laboratories to a completely online learning environment. The need for simple and engaging remote physics laboratories became apparent. One relatively low-cost remote lab system is Macmillan's iOLab device. This…
