Matsutani, Akihiro – Physics Education, 2021
In the violin, the fundamental air cavity mode (the A0 mode) is associated with the sound radiated by the f-holes. The dependences of the sound velocity of the A0 frequency on gaseous temperature and mass were investigated. It was found that the frequency of the A0 mode changed, depending on the molecular weight and the temperature of the gas…

Balabanoff, Morgan; Kaur, Simreen; Barbera, Jack; Moon, Alena – International Journal of Science Education, 2022
Across science disciplines, light is a common tool for measuring, characterizing, and catalysing molecules and molecular processes. Despite the ubiquity of light-based tools, little research has been done to investigate how students understand light and light-matter interactions (LMI). This topic is typically first introduced in first-year…

Zhao, Yanlu; Lim, Minyoung; Choi, Sungmoon; Yu, Junhua – Journal of Biological Education, 2022
The attractive photophysical properties of luminescent nanoparticles have prompted numerous studies on their synthesis and biological applications. Due to the complexity of components, sizes, morphologies, and strong light scattering of the nanoparticles the absorption spectrum alone is not enough for characterising and analysing the real…

Baji, Fatima; Haeusler, Carole – Research in Science Education, 2022
In common with many other countries, the Iranian science curriculum does not introduce primary children to atoms and molecules but instead leaves the teaching of these concepts until high school. This paper challenges this practice and describes the changes in elementary Iranian children's understanding of atoms and molecules following a 10-h…

Di Vincenzo, Antonella; Floriano, Michele A. – Journal of Chemical Education, 2020
An application for visualizing the dynamic properties of an equimolar binary mixture of isotropic reactive particles is presented. By introducing a user selectable choice for the activation energy, the application is useful to demonstrate qualitatively that the reaction rate depends on the above choice and on temperature. The application is based…

Lukovic, Milentije – Physics Teacher, 2019
Friction is one of the common forces that affect our everyday life and one of the oldest problems studied in physics. An interpretation of its nature is included in all general physics courses, in both high school and college. The desire and need to better understand it guided a long list of scientists who devoted themselves to the study of…

VandenPlas, Jessica R.; Herrington, Deborah G.; Shrode, Alec D.; Sweeder, Ryan D. – Journal of Chemical Education, 2021
The growing popularity of flipped, blended, and online learning, combined with the need to support a student population with increasingly diverse backgrounds, has led to the development and use of online materials to support students' learning of chemistry outside of a face-to-face classroom. Chemistry simulations provide opportunities to make…

Yonai, Ella; Blonder, Ron – Physical Review Physics Education Research, 2020
The goal of this research is to provide a rich set of connections between two fields: (i) Nanoscale science and technology (NST) and (ii) topics from a common middle school physics curriculum. NST is emerging as one of the most promising new fields of the 21st century, which is one of the many arguments for including NST topics in secondary…

Wiener, Gerfried J.; Schmeling, Sascha M.; Hopf, Martin – Physics Education, 2017
We present a new learning unit, which introduces 12 year-olds to the subatomic structure of matter. The learning unit was iteratively developed as a design-based research project using the technique of probing acceptance. We give a brief overview of the unit's final version, discuss its key ideas and main concepts, and conclude by highlighting the…

Johnstone, Erik V.; Yates, Mary Anne; Poineau, Frederic; Sattelberger, Alfred P.; Czerwinski, Kenneth R. – Journal of Chemical Education, 2017
The radioactive nature of technetium is discussed using a combination of introductory nuclear physics concepts and empirical trends observed in the chart of the nuclides and the periodic table of the elements. Trends such as the enhanced stability of nucleon pairs, magic numbers, and Mattauch's rule are described. The concepts of nuclear binding…

Woo, Yura; Ju, Young-Gu – Physics Education, 2019
In this paper, we present the details of the development of a smartphone spectrometer for education using a 3D printer and characterized the performance by comparison with a paper craft spectrometer. The optical design and the narrow slit used in the build resulted in the formation of accurate images of the slit on the image sensor leading to a…

Kohn, Kathryn Paris – ProQuest LLC, 2018
Despite the number of university students who take courses in multiple science disciplines, little is known about how they perceive common concepts from different disciplinary perspectives and to what extent they recognize connections among their courses. This dissertation explores students' perceptions of their chemistry and biology courses…

Ozkan, Gulbin; Sezgin Selcuk, Gamze – Asia-Pacific Forum on Science Learning and Teaching, 2013
Misconceptions are the number one factor leading students to failure when studying physics. To teach physics effectively, misconceptions must be spotted and overcome. Conceptual change texts are of great use in identifying and dealing with fallacies. Such texts can help physics teachers diagnose student misconceptions and the reasons for these,…
