Rybin, V.; Semynin, M.; Rudyi, S.; Rozhdestvensky, Yu – Physics Education, 2022
We present a simple and affordable method for making a surface electrodynamic trap for microparticles. The principles of electrodynamic trapping of charged particles are discussed and step-by-step instructions on how to make a surface trap are given. In addition to the electrodynamic trap implementation and operation process, options for its…

Mayta, Martín L.; Dotto, Marcela; Orellano, Elena G.; Krapp, Adriana R. – Biochemistry and Molecular Biology Education, 2022
The CRISPR/Cas9 system is widely used for editing genes in various organisms and is a very useful tool due to its versatility, simplicity, and efficiency. To teach its principles to post-graduate students we designed a laboratory activity to obtain and analyze PDS3 mutants in "Arabidopsis thaliana" plants consisting of: 1) Design of…

Ha, Hyejin; Jang, Taehun; Sohn, Sang Ho; Kim, Junghwa – Physics Teacher, 2022
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…

Karine Molvinger – Journal of Chemical Education, 2024
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…

Kelsey S. Bitting; Katherine Ryker; Rachel Teasdale – Journal of Geoscience Education, 2024
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…

Krystal Dawn Grieger – ProQuest LLC, 2024
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…

Simbarashe Nkomo; Alia Bly – Journal of Chemical Education, 2024
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…

Adrian Harrison; Gareth Evans; Gonzalo Blanco – Journal of Microbiology & Biology Education, 2024
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…

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…

Stanga, John P.; Nash, Troy R.; Pannell, Megan D. – American Biology Teacher, 2023
Concepts relating to enzymes and energy are central to understanding chemical and biological processes at the molecular level. Student learning of these crosscutting concepts can be challenging, so it is important to identify misconceptions and remediate them early, especially in introductory classes. Here we describe an activity in which…

Lockard, Joe; Goggin, Peter – Science & Education, 2023
The paper describes an upper-division university course in Mars literature taught online since Fall 2013. The course readings comprise six novels relating to Mars. Authors include H.G. Wells, Edgar Rice Burroughs, Ray Bradbury, Phillip K. Dick, Greg Bear, and Kim Stanley Robinson. After an introduction, sections of the paper discuss course…

Jonathan Andicoechea Fischmann – ProQuest LLC, 2023
This dissertation investigates how the numerical representation of women in small collaborative groups influences their learning in a college biology class for non-majors focused on sex, gender, and society. Prior to the start of the semester, the researchers divided students into all-male, all-female, or mixed-gender groups of varying sex ratios.…

Adrian Saura-Sanmartin; Jorge Lopez-Sanchez; Carmen Lopez-Leonardo; Aurelia Pastor; Jose Berna – Journal of Chemical Education, 2023
The synthesis of a [2]rotaxane through three- or five-component coupling reactions has been adapted to an organic chemistry experiment for upper-division students. The experimental procedure addresses the search for the most favorable reaction conditions for the synthesis of the interlocked compound, which is obtained in a yield of up to 71%.…

Metabolic Control Analysis (MCA) is a systems biology approach that measures the control of a metabolic step on the overall flux of a metabolic pathway. In undergraduate courses in biochemistry, learning of MCA can be encouraged by experimental activities demonstrating practical applications of the MCA theory. In this work, we present a laboratory…

Ifat Parveen; Michael Rose; Helen C. Phillips; Stephen E. Flower; Timothy J. Woodman; Cameron A. Garty; Michael D. Threadgill – Journal of Chemical Education, 2023
An understanding of basic organic chemical reactivity is key for many biosciences students. The reactivities of different carbonyl groups affect their function in many biomolecules. A practical class, the two-step synthesis of paracetamol, has been devised to illustrate the electrophilic reactivities of carbonyls, which was covered in the…
