Phayphung, Wissarut; Rakkapao, Suttida; Prasitpong, Singha – Physics Education, 2022
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…

Oliveira, Vitor – Physics Education, 2022
We discuss the limits of the equation of the period of a simple pendulum, T[subscript s] = 2[pi][square root]l/g, frequently used in high-school and university classrooms to measure the acceleration of gravity. We evaluate the relative error in determining the acceleration of gravity with this simple equation instead of a more realistic one,…

Ali, Numan; Ullah, Sehat; Khan, Dawar – Education and Information Technologies, 2022
Virtual Chemistry Laboratories (VCLs) are used as an alternative to the physical laboratories, where users can enhance their performance for hands-on chemistry experiments. However, cognitive load and other issues make the VCLs impractical. The issue of cognitive load arises due to the complexity of the environment by displaying a number of…

Lindén, Johan; Anttu, Nicklas – Physics Education, 2022
The falling rod paradox, i.e. the fact that the tip of an almost horizontal rod falls with an acceleration 'higher than g', when the other end is hinged or supported, is a popular physics demonstration. It can be visualized by placing e.g. a coin on the tip of the rod and fixing a cup next to the coin. When the rod is released the free-falling…

Food safety science is an important field due to its practical applications in maintaining public safety and confidence in consumer goods. A significant component of food safety science is the detection and regulation of heavy metals in food. Heavy metals such as mercury (Hg) are of particular concern because of their potential to damage the…

Novel biomaterial development is a rapidly growing field that is crucial because biomaterial fouling, due to rapid and irreversible protein adsorption, leads to cellular responses and potentially detrimental consequences such as surface thrombosis, biofilm formation, or inflammation. Therefore, biomaterial technology's fundamentals, like material…

Handan Ürek – Journal of Science Education and Technology, 2024
Science education at different levels can be supported by various mobile applications that can be downloaded for free onto mobile phones, tablets, and other devices. Such applications can also be used in laboratory work, but it must be said that their use in science laboratories is a relatively new approach. This study is aimed at determining the…

Vázquez-Bernal, Bartolomé; Jiménez-Pérez, Roque – Science & Education, 2023
The objective of this work was the theoretical modeling of a construct based on teaching practice about the perception that pupils have of difficulties in problem solving (PS) in experimental sciences, specifically physics, to predict pupil performance in PS. The research was carried out with an incidental sample of second year of secondary…

The recent Next Generation Science Standards recommend students have increased opportunities engaging in modeling work scientists do. Science classroom tasks include simple inquiry compared to more complex authentic inquiry that closely resembles authentic science. Science fair participation presents students with the opportunity to engage in…

Kirchhoff, Tim; Randler, Christoph; Großmann, Nadine – Journal of Research in Science Teaching, 2023
All over the world, educational science outreach programs in which students can perform laboratory work have been developed. A common goal of these programs is to counteract students' decreasing motivation in STEM education. In Germany, several outreach science labs have been established over the last 20 years. It is assumed that the…

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…
