A laboratory experiment was designed to introduce the practical application of biocatalysis in Bachelor and Master courses in biotechnology and medicinal chemistry, respectively. To this aim, the lipase from "Candida rugosa" was characterized (protein concentration and activity), immobilized on a carrier (by hydrophobic adsorption), and…

The teaching of laboratory skills to undergraduate students is central to all experimental sciences. In this setting, students must understand the experimental procedures as well as the fundamental principle(s) being demonstrated, all while learning within a limited time. Other limiting factors include access to equipment and reagents, resulting…

The COVID-19 outbreak represented a remarkable challenge in universities and colleges since it forced the transition from a face-to-face model in classrooms and laboratories to a remote, online model using computers, tablets, and cell phones. In Mexico and other Latin American countries, the return to educational activities was a slow-paced…

Regulation is a key concept for understanding the dynamics of metabolism in bacteria. This report outlines a simple laboratory experiment aimed at studying a key form of regulation in bacterial metabolism, exemplifying how microbes switch the flux of carbon towards alternative metabolic fates as a function of nutrient availability and according to…

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.…

A class of 18 students attending the last year of an Italian high school was divided into groups and performed the extraction of pigments contained in hibiscus tea. Each group worked at a different temperature and carried out multiple extractions using distilled water as a solvent. By means of UV-vis spectroscopy it was possible to determine the…

This study aims to: Produce teaching materials in the form of microbiology e-books based on research results on the isolation of styrofoam degrading soil bacteria. Testing the effect of using e-books on improving students' science process skills. The e-book preparation method refers to the Lee and Owens development model and is implemented in…

Acknowledgement of the limited learning outcomes in our first-year physics lab course, strikingly similar to the observed and reported issues in literature, incited renewal of the course with a focus on developing students' ability to engage in experimental physics research. The "procedural and conceptual knowledge (PACKS)…

The aim of this study was to determine the attitudes towards laboratory skills and chemistry laboratory anxieties of pre-service science teachers who were currently registered to general chemistry laboratory course and who had taken this course previously. To evaluate candidates' attitudes and anxieties in line with this purpose, they were…

Inquiry-based learning can be an effective approach when students are provided with sufficient guidance. However, there is an ongoing debate among practitioners about the nature, type, and level of such guidance. This study investigated the effects on middle school students' (N = 116) conceptual knowledge and inquiry skills acquisition of…

Development of key practical skills is fundamental to bioscience courses in higher education. With limitations on access to laboratory time due to the COVID-19 pandemic, a "Bioskills at home" kit was developed to create opportunities for first year undergraduate students to develop these skills using online support resources to guide…

To become scientifically literate, students must learn to proficiently utilise and fluently integrate a suite of specialised and contextualised multimodal literacy practices. While the frequency of explicit reading and writing instruction in the sciences is increasing, the wider range of multimodal practices are often not adequately addressed. We…

In the field of science education, laboratory learning environment has gained renewed interest in the recent decade. This study aimed to investigate the relationships among students' conceptions of science laboratory learning, perceptions of the science laboratory learning environment, and their academic self-efficacy in science learning by…

Due to the coronavirus lockdown, home experiments were devised for our first-year physics lab course. In this practitioner contribution we elaborate on the guided inquiries that were set up. Students could carry out the experiments with standard tools available at home, including sensors mobile phones are equipped with. Various design principles…

Aim/Purpose: The objective of this study is to explore the effectiveness of using virtual experiments on students' level of achievement and on their practical skills as well as their views on applying the virtual experiments in a general physics lab. Background: There is a continuous debate in the literature on the effect of using virtual…
