In this article, we propose a simple and accessible model of a magnetic levitator fitted with a Hall sensor. This model also allows to determine the magnitude of the magnetic field within the levitator working volume. Students can also compare the experimental magnetic field values to reference values in magnetism textbooks. This Arduino-based…

Pulse oximetry has become the standard of care in operating rooms, intensive care units, and hospitals worldwide. A pulse oximeter continuously and noninvasively monitors the functional oxygen saturation of hemoglobin in arterial blood (Sa[subscript O2]). Sa[subscript O2] is so important in medical care that it is often regarded as a fifth vital…

While previous literature finds many benefits to participation in undergraduate field courses, the mechanisms for how these benefits develop is still unknown. This study explores these mechanisms and any unique benefits of field courses by examining results from pre and post surveys about scientific literacy, future science plans, and motivation…

CRISPR is a technique increasingly used in the laboratory for both fundamental and applied research. We designed and implemented a lab experience for undergraduates to carry out CRISPR technology in the lab, and knockout the wing patterning genes "optix" and "WntA" in "Vanessa cardui" butterflies. Students obtained…

The aim of the present study was to explore the nature of visual representations in biology textbooks across five educational boards across Asia through quantitative and qualitative content analysis. Descriptive statistics was used during the quantitative analysis. Qualitative content analysis involved a deductive approach where visuals in these…

This study investigated the effect of dialogic practical work on students' attitudes toward physics. The sample of the study was 91 grade 11 secondary school students selected randomly from two schools in Bahir Dar town, Ethiopia. A quasi-experimental pretest-posttest between groups research design was used. The treatment group participated in…

This study assessed the knowledge, feelings, and life experiences of students in public middle schools in the Brazilian Amazon toward aquatic mammals by applying semi-structured interviews, with a qualitative-quantitative approach. A total of 241 students, from all genders, aged between 12 and 14 years old, from four public schools of Pará State…

Argumentation activities in the science classroom bring students' social relationships to the forefront, which can make it difficult for a student who is marginalized in peer relationships to participate in discussions. In this study, we qualitatively analyzed how a marginalized student's attempts to position himself as an accepted member of…

This research aims to design a sample Arduino-assisted robotics and coding activity in accordance with the 5E instructional model. Also, it aims to set an example for how technology is integrated into science courses, especially in the structuring of abstract and hard-to-understand concepts in science teaching. The activity provides guidance to…

The static equilibrium properties of a spool, resting on an incline and subject to the tension exerted by a string wrapped around the core cylinder, are studied by means of Newtonian mechanics. The overall behaviour of this system is imagined to be similar to that of a doggie kept on a leash. Starting from the well-known mechanical properties of…

This paper seeks to evaluate learning based on the competency approach, taking a didactic experience to evaluate a possible improvement in the ability to solve problems and for autonomous learning in general. For the didactic development, the theme "gases" was taken, which is generally enunciated: Corpuscular kinetic theory of matter;…

New educational initiatives and government organizations suggest the implementation of STEM (science, technology, engineering, and mathematics) lessons should begin at the elementary level as a primary means of inspiring young students to pursue these subjects and careers later in life. However, research supports the claim that elementary teachers…

Visualizations are commonly used in educational materials, however not all visualizations are equally effective at promoting learning. Prior research has supported the idea that both perceptually rich and bland visualizations are beneficial for learning and generalization. We investigated whether the perceptual richness of a life cycle diagram…

In order to comprehend complex and abstract phenomena, students must partake in the process of learning by integrating complex and invisible components without ever physically encountering or manipulating such components. Prior knowledge and experiences will influence the way students assimilate and model new experiences and knowledge. If prior…

With changes in cadaver availability, ongoing innovations in technology, and rising pedagogical changes, the field of anatomy education is amidst adaptations. In the field of occupational therapy (OT) education, anatomy is often part of the core curriculum. The problem was the limited literature on technology tools being used by educators in OT…
