Tyler A. Shaffer; Carlos U. Herrada; Avery M. Walker; Laura D. Casto-Boggess; Lisa A. Holland; Timothy R. Johnson; Megan E. Jones; Yousef S. Elshamy – Journal of Chemical Education, 2023
Electrophoresis is integral to analytical and biochemistry experiences in undergraduate education; however, fundamental principles of the method are often taught in upper-level laboratories through hands-on experiences. A laboratory activity is reported that teaches the concepts of electrophoretic mobility and electroosmotic flow. A single…

Inêz, Tiago Guimarães; de Lacerda Brito, Breno Pascal; El-Hani, Charbel N. – Science & Education, 2023
It has been shown that many people do not understand how scientific knowledge is built and accepted, even after scientific education. One way to deal with this problem is through teaching about the Nature of Science (NOS). NOS can be understood as a pedagogical construct aiming to foster the understanding of the main characteristics of scientific…

Turley, Emma L. – Qualitative Research Journal, 2023
Purpose: Phenomenology has a long tradition as a qualitative research method in the social and health sciences. The application of phenomenological methods to understand lived experiences and subjectivities offers researchers a rich tapestry of methodological approaches, often however, the availability of these methods to researchers is tempered…

Young, Douglas T. – Physics Teacher, 2023
Experiments involving RC circuits are an integral part of introductory physics courses. Previous articles using RC circuits describe determining the charge on a Van de Graaff generator, measuring currents and voltages in a charging RC circuit using a multimeter or an Arduino, measuring the decay constants of complex RC circuits, and using the…

Sarkar, Soumen; Pal, Sanjoy Kumar; Chakrabarti, Surajit – Physics Teacher, 2023
A smartphone is a powerful learning aid in the hands of a large section of students around the world. The camera of the phone can be used for several learning purposes apart from its obvious purpose of photographing. If the focal length of the lens of the camera can be determined, several experiments in optics can be performed with it. In some…

Fletcher, Kurtis A.; Lallier, Nicole M.; Masman, Jack M. – Physics Teacher, 2023
Inspired by a commercially produced scattering experiment that was popular beginning in the 1960s, we have developed a Nerf-projectile-based educational activity to demonstrate the basics of particle scattering experiments.

Muhammet Fatih Dogan – Acta Didactica Napocensia, 2023
In this study, educational programs that have been used from past to present were examined chronologically to better analyze the nature of the current Science program in primary schools in Turkey. In this research, in which the document analysis method was preferred among the qualitative research methods, official documents published by the…

Peterson, Elizabeth Sarah – ProQuest LLC, 2023
Moving Beyond the Ordinal Methodological Controversy: A Systematic Review (Manuscript 1): Ordinal outcome data is a common byproduct of education research. Yet more than seventy-five years after the development of Stevens' original measurement framework, the permissibility of select analytic techniques to ordinal outcome data remains a topic of…

Nathaniel A. Omilani; Ime Ajibola – African Journal of Research in Mathematics, Science and Technology Education, 2023
This study surveyed 19 chemistry teachers' stoichiometry pedagogical content knowledge (SPCK) in Ijebu Ode local government area of Ogun state, Nigeria using Malcolm's Physical Science Teachers' SPCK test. The qualitative data were transformed to scores, which revealed the level of chemistry teachers' knowledge of students' prior knowledge,…

Ted M. Clark – Journal of Chemical Education, 2023
The artificial intelligence chatbot ChatGPT was used to answer questions from final exams administered in two general chemistry courses, including questions with closed-response format and with open-response format. For closed-response questions, ChatGPT was very capable at identifying the concept even when the question included a great deal of…

Xiang Wan; Dian Wang; Yuqing He; Jiafei Wang; Qin Xu; Donglin Zhao; Fazhi Xie; Qishu Qu – Journal of Chemical Education, 2023
High-performance liquid chromatography (HPLC) experiments are an important part of the undergraduate analytical instrumentation laboratory courses and usually use commercial C18 silica-packed reversed-phase columns. In this experiment, a simple method of preparing SiO[subscript 2] core-shell packed columns was developed to enable students to…

Valeria Edelsztein – Journal of Chemical Education, 2023
High school students and students in the first years of college have difficulties in understanding the topic of stoichiometry and, in particular, the concept of limiting reactant. Proposals aimed at overcoming these learning obstacles tend to focus on analogies, and there are few sequences that approach teaching from an experimental perspective.…

Philipp Meyer – Journal of Chemical Education, 2023
Although diffusion is the subject of beginning chemistry classes, there are a variety of experiments, such as the spread of perfume in the classroom, that are often "incorrectly" explained by diffusion alone. To eliminate this common misconception, a recently published method is modified to determine the diffusion constant of hydrogen…

Griffith, Jonathan; Kozick-Kingston, Margaret – Science Teacher, 2022
Model-based inquiry (MBI) is an instructional framework designed around the construction, revision, and testing of models by students to make sense of and explain a phenomenon (Windschitl et al. 2008). Focusing on explaining natural phenomena provides a specific context for students to learn and apply scientific understandings to and can help…
