The Case Study (CS) method is a teaching methodology based on constructivism and centered on students, which actively develops their learning. Through the study of a case, which can be a real or fictional story based on everyday life, the student is asked to solve a dilemma and thus is expected to develop higher skills. Through this systematic…

Coetzee, Coréne; Rollnick, Marissa; Gaigher, Estelle – Research in Science Education, 2022
This paper reports on topic-specific pedagogical content knowledge (PCK) enacted by three pre-service science teachers during their final year school-based internship. An interpretive, qualitative case study was conducted to investigate to what extent the pre-service teachers applied the knowledge taught during a preceding physical science method…

Das, K. Rohini; Antony, M. Jinish – Journal of Chemical Education, 2022
For the present lab demonstration, we have developed fluorescent indicators to detect the end point in microscale redox titration of ferrous ions in permanganometry, cerimetry, and dichrometry. Microscale redox titrations were carried out effectively in micromolar(µM) concentrations and semi-microvolumes of the analytes. At the end point,…

Caldero´n-Mendoza, Gina L.; Esponda-Vela´squez, Roberto I.; Valle-Sua´rez, Renata M.; Ponce-Rodri´guez, Henry D. – Journal of Chemical Education, 2022
The development and application of a simulator designed with Excel spreadsheets to teach procedural skills in atomic absorption spectrometry and atomic emission spectrometry are proposed. For the development of the simulator, different analytical procedures were followed including analysis of pharmaceutical, forensic, and environmental samples.…

Kim, Soyeon; Lee, Soyeon; Moon, Su Jin; Kim, Kyuhwan; Kim, Jung Bog – Physics Education, 2022
Since the vibration of a single pendulum is very periodic, measuring its period is a very interesting topic. When students are asked to measure the period of a single vibration, they start and stop the stopwatch when the pendulum reaches the top point as a reference point. In this paper, we try to show that the error can be reduced more by using…

Hardy, Lisa; Dixon, Colin; Van Doren, Seth; Hsi, Sherry – Science Teacher, 2022
In science classrooms, students usually see and work with data that's intended to tell them right away about the natural world. Students then often treat the data we provide to them as factual, rather than as a source of evidence (Duschl 2008; Sandoval and Millwood 2005; Berland and Reiser 2009; McNeill and Berland 2017; Hancock, Kaput, and…

Chen, Audrey; Tarapore, Eric; To, Allisen G.; Catolico, Davis M.; Nguyen, Kelly C.; Coleman, Melissa J.; Spence, Rory D. – Biochemistry and Molecular Biology Education, 2022
Widely used in research laboratories, immunohistochemistry (IHC) is a transferable skill that prepares undergraduate students for a variety of careers in the biomedical field. We have developed an inquiry-based learning IHC laboratory exercise, which introduces students to the theory, procedure, and data interpretation of antibody staining.…

Horikoshi, Ryo; Shirotani, Dai; Shioyama, Hiroshi – Journal of Chemical Education, 2022
Buckminsterfullerene (C[subscript 60]), along with diamond and graphite, appears in many chemistry textbooks as an example of an allotrope of carbon. This communication describes a hands-on activity to explore the characteristic structure of C[subscript 60] through the construction of a structural model using transistors and plastic tubes…

Flaherty, Aishling – Journal of Chemical Education, 2022
Engaging in laboratory practical activities, developing laboratory practical skills, and, to a degree, even wearing laboratory protective equipment such as safety coats and goggles are all quintessential components of chemistry education. It is becoming quite common for institutions to invest in large-scale chemistry teaching laboratories, filling…

An undergraduate laboratory was developed as part of the Drugs for Neglected Diseases "initiative's" Open Synthesis Network. This activity aimed to develop new compounds efficacious against visceral leishmaniasis. Students successfully synthesized, purified, and characterized ten different benzoxazole amides that were sent for biological…

Kaps, A.; Stallmach, F. – Physics Teacher, 2022
In physics lessons at secondary school and experimental physics courses at universities, the magnetic field inside a current-carrying solenoid is considered quantitatively. The corresponding equations and theories are supported by measuring the magnetic flux density inside the solenoid with a Hall probe. It has already been shown that smartphones…

Tarigan, Hendra Jaya – Physics Teacher, 2022
We describe here a low-cost experiment for introductory physics students where they compare the physical properties of aluminum and steel by means of cantilever oscillations. This, in turn, allows the students to improve their physical intuition about these materials. Further, the students can apply their physics and mathematics knowledge and…

Pfaender, J.; Gratton, L. M.; Rosi, T.; Onorato, P.; Malgieri, M. – Physics Teacher, 2022
In the last decades spectroscopy began to play an essential role in physics education research with the recognition that atomic spectra constitute a good occasion to study the concepts of quantum mechanics. Moreover, activities in which atomic spectra are studied in order to understand star structure and evolution have proved particularly engaging…

Larison, Karen D. – Teaching in Higher Education, 2022
Although students in college science courses typically learn laboratory techniques and practices, few are taught about the communicative interactions that occur within the larger scientific community. In this paper, I propose that to educate a scientifically literate public -- one that comprehends the centrality of argument in the production of…

Posey, Julianna; Lavik, Erin – Journal of Chemical Education, 2022
The biographical stories of scientists and engineers, particularly those from historically excluded groups, have been integrated into the curriculum for a materials science course. The goal is to help students connect and relate to the scientific content, while opening the door to conversations about social justice in the virtual classroom. We…
