Meaningful pedagogical reform requires good faculty training and support programs. Such support is particularly valuable when colleges and universities are trying to bring research and inquiry into the laboratory curricula under resource-limited conditions. In this situation, it may help to extend the scope of the faculty support program to…

A new experiment using laser ablation with inductively coupled plasma mass spectrometry (LA-ICP-MS) was designed for chemistry undergraduate students. While most analytical methods only provide information on the amount of the analyte, LA-ICP-MS allows extra information on the distribution of the element in the sample. Because it achieves…

Wheat powdery mildew is an important fungal pathogen of wheat with an obligatory biotrophic lifestyle (a parasite that can only develop on a living host). We investigated the genetics of this host-pathogen interaction by using phenotyping and PCR assays to detect genes in both wheat and powdery mildew, which are known determinants of the outcome…

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…

COVID-19 has caused major disruptions in the way engineering education is conducted all over the world. The impact has been greater in developing countries that still lack the necessary tools for pandemic-based training. In this work, we carry out a survey on three public universities based in Zambia. The survey investigates the impact of COVID-19…

Here we showcase an undergraduate teaching laboratory in which students synthesize and characterize colloidal nanoparticles of organic semiconductors and assess their suitability for applications in printed electronics such as solar cells and bioelectronics. Scanning electron microscopy, UV-visible spectroscopy, and photoluminescence spectroscopy…

This paper addresses the fundamentals, structuring, and application of a Formative Dimensions for Green and Sustainable Chemical Education (Formative Dimensions -- GSCE) qualitative evaluation tool of experimental processes. This instrument was created considering the need to resignify laboratory practices in Chemical Education. Qualitative…

Virtual laboratories (VLs) enable students to experiment, analyze data, or interact with digital content in a nonphysical space. VLs include simulations, electronic notebooks, videos, and augmented reality. As part of the "VL Project," comprising five academic institutions in Ireland, we sought to determine how VLs might enhance…

Background: Physics textbooks are a learning resource for students to acquire knowledge and information. The findings of previous studies on physics textbooks analysis have mostly focused on representations of gender, the nature of science, and scientific literacy. This study, therefore, extends the critical content analysis of physics textbooks…

This paper describes a case study of an online physics laboratory course implemented for 254 engineering students at Walailak University in Thailand in response to the COVID-19 pandemic. The laboratory sequence was designed based on the United Kingdom Professional Standards Framework and covered eight experiments on fundamental concepts of motion,…

The current dropout rate in physics studies in Germany is about 60%, with the majority of dropouts occurring in the first year. Consequently, the physics study entry phase poses a significant challenge for many students. Students' stress perceptions can provide more profound insights into the processes and challenges during that period. In a panel…

Despite the growing importance of agricultural microbiology at the applied, productive and ecological levels, undergraduate degrees in Agronomy generally do not feature much microbiological experimentation. To address this deficiency, we have designed an experimental programme that evaluates the potential of plant growth-promoting rhizobacteria…

This paper reports the quantification of Ca, Mg, and Fe as micronutrients in different vegetables (spinach, sugar beets, and carrots) from raw and processed samples. Simple extraction procedures, titrations, and spectrophotometric analysis were used to determine the amounts of micronutrients before and after cooking. From the obtained results, an…

Over the past few decades, the photographic process has slowly vanished from chemistry education in most schools. It happened due to vast changes in both technology and legislation. It is, however, helpful in demonstrating several concepts in natural sciences, bringing a bit of art into the subjects, and giving students an opportunity to express…

In recent years, pedagogical advancements have allowed the adoption of more engaging forms of course assignments to help students better understand and communicate chemistry. In this context, informational graphics, known as infographics, emerge as an effective teaching aid in educational settings and in disseminating scientific content to the…
