The extinguishment of the candle flame in the well-known candle-and-cylinder experiment has been erroneously viewed as caused by the complete consumption of oxygen, for many reasons. To address this misconception scientifically, a series of experiments are carried out to illustrate the phenomenon from a new point of view. Limewater…

Protein engineering represents a modern approach to generate novel proteins for the different fields of biotechnology. Here, we report about an 8-day laboratory activity in which students generate enzyme variants to degrade the herbicide glyphosate. The students conduct a true research experiment in an important field (bioremediation by novel,…

In a classical electronic laboratory, there is an experiment where a diode is connected in a series with a resistor and a variable DC voltage source in order to draw the characteristic I-V curve of the diode. Input voltage is gradually increased starting from 0 V, and the potential difference between the diode's terminals is read by using a…

New learning strategies try to extend the use of common devices among students in physics lab practices. In particular, there is a recent trend to explore the possibilities of using smartphone sensors to describe physics phenomena. On the other hand, the study of the moment of inertia by the use of the torsion pendulum is a typical example in the…

A method for using electronic structure calculations to predict the standard molar enthalpy of combustion for hydrocarbons is presented. In this approach, simple geometry optimizations can be used to accurately compute the enthalpy of combustion within 3% of the experimental value using Hartree-Fock, MP2, or virtually any functional in density…

Despite pressures and incentives, faculty, academic staff, and graduate students struggle to turn outreach and engagement activities into scholarly publications. Publishing challenges include competing professional responsibilities, limited collegial support, difficulty in prioritizing time to write, professional isolation, and lack of confidence…

In many Global South countries, including South Africa, the adoption of Virtual Lab (VL) remains largely conceptual. This paper emphasizes the necessity of understanding teachers' perceptions of VL before implementation to mitigate risks of abandonment or underutilization post deployment. Guided by the Technology Acceptance Model (Davis, 1989),…

Perturbation of gene expression using RNA interference (RNAi) or CRISPR interference (CRISPRi) is a useful strategy to explore the function of essential genes. In the archaeon "Haloferax volcanii," the CRISPR-Cas system has been adapted as a CRISPRi tool to silence the expression of specific genes. We developed a laboratory class (LC) to…

Laboratories play a central role in engineering education. Current technology enables virtual experiences that challenge the traditional concept of teaching laboratories for undergraduate engineering students. Integrating technology, such as virtual laboratories, allows students to learn foundational experimental skills; however, it lacks…

The forming of microplastics in the environment continues be a global problem with damaging risks to ecosystems and human health. Currently, most microplastic studies concentrate on water and air, while research focus on terrestrial samples such as soil still lags behind. This project reports the first results of our effort to develop and…

Laboratory management is crucial in improving the quality of chemistry learning in senior high schools. However, there has been limited research on the managerial competence of chemistry teachers in managing laboratories. This study aims to analyze the managerial competence of high school chemistry teachers in laboratory management. The study used…

The objective of the study was to explore STEAM disciplines through robotics within the Future Classroom Lab (FCL) spaces, which challenge the learning of mathematical knowledge in Primary Education. The method used was quantitative and descriptive, based on data obtained from the mean and standard deviation through pre-test and post-test…

English writing centers at Chinese universities present a fascinating paradox. On one hand, the number of universities with writing centers and the professional interest in writing centers in China have grown steadily over the past two decades. But on the other, the number of centers is still modest and only a few centers have had a significant…

Generative AI tools, including the popular ChatGPT, have had a significant impact on discourses about future work and educational practices. Previous research in science education has highlighted the potential of generative AI in various education-related areas, including generating valuable discussion material, solving physics problems, and…

Practitioners of the mentor mindset in academic settings maintain high standards while providing strong support in and outside the classroom. They encourage the growth mindset by being motivating and transparent, reducing stress, and providing feedback that can help intellectual growth. The mentor mindset is the foundation of the professional…
