Setiaji, Bayu; Santoso, Purwoko Haryadi – International Review of Research in Open and Distributed Learning, 2023
The COVID-19 pandemic has constituted a sudden educational transformation around the world. It has disrupted instructors, including physics educators, forcing them to adjust to remote teaching. The hands-on laboratory, one of the components of physics instruction, has also had to rapidly go online in all branches of this science, including nuclear…

Killpack, Tess L.; Popolizio, Thea R. – Journal of Microbiology & Biology Education, 2023
Laboratory courses can serve as important avenues to equitably support introductory biology students to develop foundational scientific literacy skills while experiencing the authentic research process. We present a model for an equity-focused redesign of an introductory organismal biology laboratory course at a teaching institution with limited…

Hands-on experiences in analytical chemistry laboratories are essential to improve students' technical skills on handling analytical glassware and instruments, but the coronavirus pandemic in 2020-2021 disrupted such learning activities. Thus, alternative remote activities are required to supplement practical skills. In this work, a new portable…

Zhu, Pengfei; Ling, Yizhou – Journal of Chemical Education, 2022
Conventional mobile phone colorimetry usually utilizes the RGB color mode to measure concentration of solutions, but the paper entitled "Determining the Amount of Copper(II) Ions in a Solution Using a Smartphone" proposes the use of hue ("H") to measure the concentration. It is pointed out that the "H" value increases…

Neat, Adam – Physics Teacher, 2022
Gravity bends light. One can argue this by reasoning that a beam of light should travel in a curved path when viewed from within an accelerating frame of reference, and then invoking Einstein's principle of equivalence, which asserts that the effects observed in an accelerating frame of reference are indistinguishable from the effects observed in…

Cross, Rod – Physics Teacher, 2022
What happens when a perfectly elastic ball collides with a completely inelastic ball? It is shown that the outcome depends on the stiffness of each ball. A standard textbook problem in mechanics is to calculate the outcome of a head-on collision between two balls using conservation of momentum and kinetic energy. It is easily shown that the…

Matsutani, Akihiro – Physics Teacher, 2022
We demonstrated that an optimally designed pinhole camera can be used as an astronomical tool to observe the libration and apparent diameter change of the Moon at night. The libration and apparent diameter change of the Moon were observed using a handmade pinhole camera with a diameter of 0.65 mm and a focal length of 400 mm. It was found that the…

Irzik, Gürol; Nola, Robert – Science & Education, 2023
The family resemblance approach to nature of science is receiving increasing attention by science educators since its inception about a decade ago. Many scholars of science education have contributed and continue to contribute to it not only theoretically but also by applying it empirically to a wide range of areas such as curriculum and textbook…

Bolduc, Kathryn C.; McCollough, Shannon L.; Stoeckman, Angela K. – Biochemistry and Molecular Biology Education, 2023
Undergraduate laboratory courses are vital for both enhancing student learning and preparing students for their future careers. Despite their importance, laboratory courses are often met with a lack of enthusiasm from students. For pre-health students specifically, laboratory courses are commonly seen as part of a check-list that needs to be…

Lopes, Andressa Rubim; Leandro, Luana Paganotto; Mariano, Maria Vitória Takemura; Posser, Thais; Franco, Jeferson – Biochemistry and Molecular Biology Education, 2023
Ethanol (EtOH) is among the most consumed drugs in the world. The behavior of humans after ingestion of this drug is characteristic: At low doses it may be excitatory and at higher doses, it may induce depressant/sedative effects. Similar effects are observed in the zebrafish experimental model ("Danio rerio"), which has about 70%…

Jacob Jan Markut; Jordi Cabana; Neal P. Mankad; Donald J. Wink – Journal of Chemical Education, 2023
A symmetry activity using student-built models was developed in line with faculty-developed pedagogical goals and a collaborative learning framework. The activity took place in a 3-h laboratory portion of an upper-division inorganic chemistry course. It required students to identify symmetry elements for seven molecules using common 2D…

Simeen Sattar – Journal of Chemical Education, 2023
Quinacridone red and violet are visually different colors, an observation confirmed by their visible reflectance spectra and CIE L*a*b* coordinates. However, their IR spectra are extremely similar. Though chemically identical, the two quinacridones are polymorphs. In this experiment, designed for and tested by nonscience majors, the pigments are…

Bishnu P. Regmi; Shantel Fleming – Journal of Chemical Education, 2023
Photochemical reactions are the reactions that are induced by light. Many of these reactions are found in natural processes, including photosynthesis and the formation and decomposition of ozone in the atmosphere. Classroom demonstrations are effective in enhancing students' learning and retention. Herein, we have developed a simple demonstration…

Jessica T. Boette; Kira M. Daniel; Josephine W. Lietzke; Shawn M. Amorde; Sean T. Roberts – Journal of Chemical Education, 2023
The addition of research-focused experiences to undergraduate chemistry laboratory courses has been shown to bolster student learning, enhance student retention in STEM, and improve student self-identity as scientists. In the area of synthetic organic chemistry, the preparation of libraries of compounds with novel optical and electronic properties…

Shuang Qiu; Dongyang Zhang; Vishal Yeddu; Cristina Cordoba; Arthur M. Blackburn; Violeta Iosub; Makhsud I. Saidaminov – Journal of Chemical Education, 2023
When structure-property relationships are discussed in inorganic chemistry and materials science, the common perception is that materials with the same composition and atomic arrangement have the same properties. In this laboratory experiment, we show that "processing"--the exact conditions under which materials are made--can in fact…
