Chen, Wei – Journal of Chemical Education, 2018
Introduction to Research is a 4-credit elective course designed for first-year undergraduate students who have a strong interest in the chemical sciences and scientific research. The rich yet accessible field of gold nanoparticles was the theme connecting a multifaceted teaching/learning experience. In the first unit, students were introduced to…

Festersen, Lea; Gilch, Peter; Reiffers, Anna; Mundt, Ramona – Journal of Chemical Education, 2018
First order processes are of paramount importance for chemical kinetics. In a well-established demonstration experiment, the flow of water out of a vertical glass tube through a capillary simulates a chemical first order process. Here, a digital version of this experiment for lecture hall demonstrations is presented. To this end, water flowing out…

Wong, Wing-Kwong; Chen, Kai-Ping; Lin, Jia-Wei – International Journal of Distance Education Technologies, 2020
The results of PISA 2015 indicate that Taiwanese students have excellent mathematical and scientific knowledge but are weak in applying such knowledge and in conducting practical experiments in the laboratory. To support students conducting practical experiments in physics laboratories, a real-time data logging system and an online tool for…

Sampaio, Cátia I.; Sousa, Luís F.; Dias, Alice M. – Journal of Chemical Education, 2020
Anthocyanins are natural pigments belonging to the flavonoid family that generate the red, blue, and purple colors of fruits, vegetables, and flowers. Their structure and color are dependent on various factors, like the pH. Anthocyanins appear red in acidic, purple in neutral, and blue in basic solutions, making them suitable for use as natural pH…

Brown, Grant R.; Dagen, Claire; O'Donnell, Ben Reilly; Graves, Jeff A. – Journal of Biological Education, 2020
We provide a protocol for rapid DNA extraction from spiders suitable for undergraduate practical sessions. Students who were previously naïve to the theory and laboratory technique of DNA barcoding were successfully able to extract and recover 29 DNA sequences from 16 species of small spiders in the family Linyphiidae. We anticipate that with…

Selco, Jodye I. – Journal of Chemical Education, 2020
How can you switch from a hands-on face-to-face chemistry course to an online course in the face of a pandemic? It is possible to have students do hands-on experiments at home. There are many readily available kitchen, drug store, and garden chemicals that can be used to illustrate the same principles in standard chemistry curricula at multiple…

Ballester, Maria; Van Hoozen, Brian; Sikora, Arthur K. – Biochemistry and Molecular Biology Education, 2020
Course specific learning outcomes are an important tool to define the scope of a course and can be very helpful when designing experiments and assessments. With slight modification, these learning outcomes can serve as a guide when transitioning to the distance learning format especially in courses with a traditional lab. Here we present such an…

Oztas Cin, Merve; Yurumezoglu, Kemal – Science Activities: Projects and Curriculum Ideas in STEM Classrooms, 2020
In this study, a process was designed, in which a lemon seed grew into a seedling, using the inquiry-based science learning approach. This aimed to increase the overall development of the scientific process skills of children and their sensitivity to nature. The germination, growth and development of a plant were meticulously and systematically…

Jeon, Young Keul; Youm, Jae Boum; Ha, Kotdaji; Woo, JooHan; Yoo, Hae Young; Leem, Chae Hun; Lee, Seung Hee; Kim, Sung Joon – Advances in Physiology Education, 2020
To understand the excitation-contraction (E-C) coupling of cardiomyocytes, including the electrophysiological mechanism of their characteristically long action potential duration, is one of the major learning goals in medical physiology. However, the integrative interpretation of the responses occurring during the contraction-relaxation cycle is…

Schulze, Tina; Quast, Günter; Bergmann, Antje; Dengler, Roman – Physics Teacher, 2020
Although nearly everyone is familiar with colors from an early age and the fundamentals of color mixing are taught at various abstraction levels throughout kindergarten to high school, we repeatedly observe that our student teachers in physics have problems in explaining the subject. Therefore, we propose an experimental setup that focuses on the…

Faletic, Sergej; Planinšic, Gorazd – Physics Education, 2020
In this paper, we present activities that help students deepen their understanding of basic electrostatics using an electroscope in combination with the photoelectric effect. The students investigate the behaviour of an isolated electroscope when the metal housing of the electroscope is charged. The activities follow the framework of the…

The catalytic hydrogenation of alkenes and alkynes is an important part of the undergraduate chemistry curriculum and is a fundamental process in chemical industry. Inquiry-based laboratory activities are presented that investigate the hydrogenation of alkynes on a nanoparticle palladium surface to form alkenes, which go on to form alkanes. Alkyne…

Owen, Bradley A.; Starvaggi, Nicholas C.; Mensah, Taylor I.; Mills, Isaac N. – Journal of Chemical Education, 2020
Thermal conductivity is generally the tool of choice for quantification of fixed gases, particularly lighter-than-air gases. Unfortunately, gas chromatography-thermal conductivity detectors (GC-TCDs) are difficult to introduce in first- and second-year chemistry courses where the cost and number of instruments, as well as the space required, is…
