Magnetic iron oxide nanoparticles were synthesized and stabilized using ammonium cations or poly(vinyl alcohol) to produce amazing materials such as safer aqueous ferrofluids, ferrogels, ferromagnetic inks, plastics, and nanopowders illustrating how versatile materials can be produced just by simple modifications. The synthesis is fast, reliable,…

Purpose: Although technology is a defining characteristic of distance education, assessment of the applicability of such resources in knowledge dissemination is greatly warranted to ensure effectivity. Hence, the purpose of this study was to assess the viability of a novel tool in teaching practical chemistry online. Design/methodology/approach:…

This study aims to determine whether team production among peer groups culturally aggregated can affect the individual student performance in an Italian university. Two further hypotheses were tested in order to verify whether students perform better in team than individually and if students culturally aggregated in team perform better than…

Loosened by the laws and regulations, Taiwan's alternative educational policy has allowed public schools to conduct school-wide curriculum transformation experiments, which is a possible opportunity for Taiwanese aborigines who have been subjected to long-term oppression and assimilation to separate from the mainstream ideological educational…

Several suggestions for the use of Mobile Phone (MP) sensors in science teaching are found in the literature, and most of them focus on proposing physics experiments that can be conducted with the aid of the sensors that commonly exist in smartphones. The proposed experiments rely on the Bring Your Own Devices (BYOD) approach, that is, students…

The development of a QR code as a barcode label contains information about the item to which it is attached. However, information on QR code development in engineering science laboratories is still limited. The aim of this research is to design the QR code lab manual for laboratory work in polytechnics engineering science course. In addition, the…

Archimedes' principle is one of the foundation subjects in physics. Normally the principle is exemplified by reference to floating boats. However, Archimedes' principle also applies to objects embedded in waterlogged ground, which can lead to the surprising result of an object weighing several tons being lifted. A practical example is presented of…

Experimentation is widely accepted as being central to science education. However, anxiety about experimentation often prevents its use. While a considerable number of studies on anxiety related to laboratory experimentation have been conducted, studies on in-class experimentation is limited. In the research study reported on here we explored the…

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,…

The COVID-19 pandemic posed significant challenges for practical teaching within the sciences. While many instructors adopted innovative alternatives to conventional practicals, many relied on digital approaches that did not give students hands-on experience. In this study we evaluate the use of 'at home' practical kits used in first year physics…

Institutional ethics review procedures aim -- in principle -- to minimise harm and evaluate risks, providing an important space to consider the safety of participants and researchers. However, literature has questioned the effectiveness of the process, particularly for reviewing 'risky' topics in a risk-averse environment. This article reports the…

The method for producing monoclonal antibodies (MAbs) was first published in 1975. MAbs have revolutionised research, diagnosis, and disease treatment approaches. While students need a good understanding of MAb production, teaching the key steps via traditional methods can be challenging. Numerous resources exist, but these focus on hybridoma…

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.…

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…

A laboratory experiment was developed for the continuous flow preparation of an aminal derived from the condensation of furfural with morpholine. The experiment introduces the students to concepts of green chemistry, heterogeneous catalysis, and continuous flow. A cheap and easy setup allows the heterogeneous catalyst reactor to be built in class.…
