A solenoid is a coil wound many times on a cylinder of length greater than its diameter. Solenoids are mainly used as electromagnets, because a magnetic field is formed when current flows through a solenoid. The solenoid described in secondary school and university textbooks is a single-layered solenoid. Further, textbooks and papers focusing on…

The direct involvement of students in conducting experiments in order to learn science has been a common part of U.S. educational practice since the late 19th century, the result of the rapid spread of what was known as the "laboratory method" of teaching. Those promoting the laboratory method recognized it as a new educational approach,…

This mixed-methods study reports the results of a survey completed by a sample of Puerto Rican social and natural scientists (STEM-S) regarding their perceptions of the intersectionalities of racism, colorism, colonialism, and the culture of science. Most participants ranked themselves as light-skinned and were familiar with the racist stereotypes…

This article focuses on the learning of the Lewis representation at the transition from high school to university, in France. Indeed, this notion is taught both in high school and in the first year of higher education but with different methods, which seems to hinder the learners. In this work, we observe 11th grade and higher education classes…

Triggered situational interest in introductory courses can encourage student engagement, motivation, and value for the geosciences. In-person labs have traditionally played a unique role in triggering situational interest compared to lectures, but the COVID transition online disrupted these dynamics. We examine students' self-reported situational…

There has been a growing emphasis on integrating green and sustainable chemistry (GSC) into the curriculum. Unfortunately, there is yet to be a nationwide, uniform decision of which aspects should be included or how, leaving individual instructors or institutions to decide whether--and how--to address GSC knowledge. Furthermore, faculty nationwide…

In undergraduate science education, laboratory courses stand as essential cornerstones of experiential learning. Chemistry laboratory courses offer students unique hands-on experiences that bridge the gap between theoretical knowledge and practical application. The journey through the undergraduate chemistry curriculum is paved with a series of…

Experimental teaching is an important part of postgraduate training in basic and clinical medicine. While primary cell isolation and identification are among the most important research techniques for medical graduate students, most graduate students do not understand and master these techniques before starting their research experience. In…

Scientific practices describe behaviors scientists engage in while investigating the natural world. Educators should be aware of different science practice frameworks to better understand their students' progression for learning science practices across the K-20 spectrum. For example, a high school AP instructor would benefit from understanding…

Within the eukaryotic cell, the actin cytoskeleton is a crucial structural framework that maintains cellular form, regulates cell movement and division, and facilitates the internal transportation of proteins and organelles. External cues induce alterations in the actin cytoskeleton primarily through the activation of Rho GTPases, which then bind…

A professional practice is a type of internship, a practicum, that encompasses a supervised hands-on training experience for students to develop and identify the core and enabling competencies required in a professional environment. It also allows them to identify the developed and underdeveloped skills that are important in the labour environment…

Current models of best practice in science education advocate for students to learn science by engaging in applied contexts that integrate the various science disciplines. Permaculture offers one such integrated context for elementary science. Although permaculture is relatively new in PK-12 education, the broader practice of school gardening has…

This study introduces a modernized approach to classical volumetric titrations for the undergraduate chemistry curriculum. Leveraging smartphones and digital top-loading balances, we performed mass-based titrations and determined end points using digital color measurements. Our aim was to make classical wet chemistry more accessible and engaging…

Programs that emphasize the important, multifaceted roles that soils play as the interfaces between humanity and the earth are needed to attract new students from diverse backgrounds. The Basic and Environmental Soil Science Training Research Experience for Undergraduates (BESST REU) site aims to provide undergraduates from a variety of science,…

Citizen science's (CS) deployment and benefit over the last ten years have been remarkably substantial in their contributions to the massification of citizen participation in tech-based CS projects. Insights into how CS projects influence community changes through proposals of actions and public policies are essential to understanding how they…
