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),…

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…

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…

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…

In conventional laboratories, engineering students must attend in person to conduct experiments with real equipment in a physical place, where their work is mainly assessed through self-reports and attendance records. By comparison, online labs can record and analyze students' activities and behaviors automatically. Thus, this article proposes a…

This article describes strategies to adapt and ensure equivalency of content coverage for an existing protein assay laboratory practical for concurrent face-to-face and online deliveries during COVID-19 and beyond.

The COVID-19 pandemic caused several educational challenges. Conducting laboratory experiments was an uphill task during the pandemic. Here, we developed a low-cost and reliable home-based experimental setup to teach column and thin layer chromatography (TLC) using silica gel granules available at home. Powdered silica gel, prepared by grinding…

[This paper is part of the Focused Collection on Instructional labs: Improving traditions and new directions.] In recent years, physics instructional labs have been under considerable research and development. However, there seems to be no shared understanding of how the assessment of instructional labs should be arranged to best serve students'…

Background: Experiential learning is commonly used in postsecondary settings, especially in undergraduate, agricultural, and laboratory courses. However, a lack of attention has been paid by educators to critical components of experiential learning. Purpose: The effects of reflection mode (peer-verbal or written journal reflection) and transfer…

Animal models are widely used in laboratory practicals in biomedical disciplines. However, experiments involving animal work are usually time-and-labor consuming. It is also costly to run an animal lab and the animal caring/holding request special training. Here we present a laboratory course design that provides students with wet lab experience…

Understanding potentiometry is a difficult task when students in initial courses of Analytical Chemistry are first introduced to instrumental techniques. The closest instrument to them is a pH meter, which is frequently used as a "black box", without a real understanding of how it works. Here we present the assembly of jelly modules that…

A major obstacle that teachers face when they begin their spectroscopy lessons is the lack of a spectrophotometer, mostly due to its relatively high cost. In the present study, the construction of a low-cost do-it-yourself type of instrument is reported. Its construction, as a part of a problem-based scenario, would also help students to enhance…

Course-Based Undergraduate Research Experiences (CUREs) have become more commonly incorporated in laboratory courses in undergraduate education. Because CUREs incorporate research within the context of a course, the benefits of mentored research (self-efficacy, science identity, persistence, and more) are extended to each student enrolled. CUREs…

This manuscript describes a laboratory exercise that allows students to use conductive atomic force microscopy (CAFM) for the analysis of electrodeposited, metallic structures. In addition to nanoscale electrical characterization with CAFM, this laboratory exercise also provides students with an opportunity to explore nanofabrication by…
