Metagenomics is a tool that enables researchers to study genetic material recovered directly from microbial communities or microbiomes. Fueled by advances in sequencing technologies, bioinformatics tools, and sample processing, metagenomics studies promise to expand our understanding of human health and the use of microorganisms for agriculture…

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…

Polychlorinated biphenyls (PCBs) are a family of synthetic chemicals consisting of carbon, hydrogen, and chlorine atoms. PCBs have been produced commercially since 1929 in hundreds of industrial applications. Their continued production in the United States was phased out in the late 1970s, and strict disposal guidelines were regulated as adverse…

At the University of South Australia (UniSA), Biochemistry is a second year undergraduate course. The student cohort is diverse, with students enrolled in courses with a laboratory focus, such as Laboratory Medicine, Medical Science, Nutrition and Food Science and Pharmaceutical Science. The course is taught in a traditional manner, with weekly…

Undergraduate students are increasingly aware of complex global challenges and have a strong desire to take action and create change. Course-based undergraduate research experiences can offer a wide range of students the opportunity to gain skills needed to address these challenges. At a small liberal arts college in New England, we developed the…

This research aimed to explore the effects of a virtual lab (VL) and a Microcomputer-based Lab (MBL) on students' performance in scientific modeling. A web-based virtual lab and a low-cost MBL were proposed to help first-year engineering students build scientific models. Empirical research was done in a slope motion experiment. The participants…

This research designed within the scope of a TUBITAK 4005 project aimed to give science teachers training on argumentation-based learning, to provide them with scientific inquiry experience, to ensure that they gain skills to develop argumentation-based experimental learning methods. Throughout the research, 100 science teachers were given a…

Recently, virtual and remote labs (VRLs) have been developed to support students in conducting experiments in engineering and science education. However, little is known about the students' intentions to continue using VRLs and their satisfaction with the experience. This study proposed an extended model embedded within the expectation…

Anatomy and Physiology should be considered a gateway course due to its challenging scope and key role as a foundational prerequisite for many degree programs. Students often encounter gateway classes early in their college career when they are academically vulnerable due to their lack of university experience. A&P teaching methods are…

In March of 2020, as New York City was becoming the global epicenter of the COVID-19 pandemic, the 3 authors, members of the Chemistry Department at Queensborough Community College--City University of New York, had 1 week to move their 13 lecture and laboratory sections of 4 different first-year undergraduate courses plus 2 active undergraduate…

The study investigated the relative effects of two activity-based instructional strategies on students' attitude towards Physics practical in secondary schools. The study adopted the quasi-experimental design of pretest, post-test and control group. The sample for the study comprised 74 Senior Secondary two (SS II) Physics students who were…

The ability to "engage in argument from evidence" is one of the eight practices identified in the "Next Generation Science Standards" as well as an emerging focus of undergraduate chemistry curricula. Guiding students to make evidence-based claims that engender argumentation will require faculty to revise conventional…

The understanding of measurement is related to the understanding of the nature of science--one of the main goals of current international science teaching at all levels of education. This case study explores how a first-year university physics course deals with measurement uncertainties in the light of an epistemological analysis of measurement.…

The voltage waveform that minimizes the energy loss in the resistance when charging the capacitor in a resistor-capacitor circuit is investigated using the calculus of variation. A linear voltage ramp gives the best efficiency, which means a constant current source should be used for charging. Comparison between constant current source and…

The paper presents a series of experiments that demonstrate the phenomenon of electromagnetic induction. These make it possible to determine the direction of the induced current and so confirm Lenz's Law. The simple experiments can be reproduced in a school laboratory and can be recommended for students' project activity.
