Cross, Rod – Physics Education, 2021
Experimental results are presented on the collision of a superball with two different wood blocks. The results are in reasonable agreement with a simple collision model where kinetic energy is conserved, but better agreement is obtained if a small loss of kinetic energy is assumed, as observed. The physics is slightly more complicated than the…

Kaps, A.; Stallmach, F. – Physics Education, 2021
A digital learning-teaching environment is introduced in which undergraduate students are challenged to connect the basic physical concepts of oscillation, buoyancy and data analysis via an authentic experiment. The damped oscillation of a cylindrical body swimming upright in water is measured via the MEMS acceleration sensor of a wireless MCU…

Chiang, Chih-Yun; Huang, Hsin-Wei; Chen, Shao-Yen; Chen, Yun-An; Chang, Yuan-Mou; Huang, Hao-Jen – Biochemistry and Molecular Biology Education, 2021
Volatile-mediated impacts of microbes on plants have aroused interest among scientists in the life science field. This study describes an inquiry-based laboratory module named "Microbial Talk", which related to microbial volatile-mediated communication, including the process of design, implementation, and assessment. First-year biology…

Cross, Rod; Gauld, Colin – Physics Education, 2021
Newton's cradle is a well-known physics toy that is commonly used by teachers to demonstrate conservation laws in mechanics. It can also be used to investigate the physics of colliding objects, by recording motion of the balls on video film. Various experiments are described using 3-ball and 5-ball cradles, showing how different types of collision…

Cross, Rod – Physics Education, 2021
The vertical bounce of a plastic egg was investigated by dropping the egg on a horizontal surface and filming the result with a video camera. If the egg is dropped on one end then it bounces just like a spherical ball. If the top end of the egg is pointing forwards or backwards when it lands on the surface, or if the egg is spinning when it lands,…

Seah, Ying Ying – ProQuest LLC, 2021
The ability to make informed decisions is a skill considered as one of the 21st century skills and is crucial as part of the critical thinking and problem-solving process in science and engineering. Despite its importance, students (e.g., beginning designers) often struggle with making informed design decisions that are well supported by relevant…

White, Gary; Sikorski, Tiffany-Rose; Landay, Justin; Ahmed, Maryam – Physical Review Physics Education Research, 2023
Limiting case analysis (LCA) is important to practicing physicists. Yet, there is little concrete guidance for physics educators, and a lack of consensus in the research community about how to help students learn, and learn from, limiting case analysis. In this study, we first review existing literature to find commonalities and variations in how…

Subramaniam, Karthigeyan – Research in Science Education, 2023
This qualitative study aimed to explore what are pre-service elementary teachers' (N = 325) conceptualizations of scientific practices prior to their entry into the science teaching methods course through their drawn images and narratives of the scientists (male and female) and teacher as scientists. Data (drawings, narratives, and responses to…

Price, J. A.; Olver, J. – Journal of Biological Education, 2023
Most undergraduate students do not have practical experience working with model organisms despite having theoretical knowledge of their importance. This practical was developed to offer students experience working with three species of nematode, including "Caenorhabditis elegans." In the first task, students prepare slides of three…

English, Lyn – International Journal of Science and Mathematics Education, 2023
This study investigated sixth-grade students' development of multidisciplinary models involving the integration of mathematics, science, and statistics, together with shared STEM practices. Mathematics and science featured a reciprocal relationship within the real-world context of tsunami inundation. Experimenting with water tubs comprising…

Yunhua Li; Weizhong Liao; Cuixue Chen; Meiling Ye; Alexander Luis Imbault – Journal of Chemical Education, 2023
The electrolysis of water to produce hydrogen is a critical step in many green chemistry processes. The key to the efficiency of water electrolysis is the synthesis of an appropriate electrocatalyst. Three-dimensional (3D) printing is an increasingly important part of many industrial processes. In this study, we propose an efficient laboratory…

Schwichow, Martin; Brandenburger, Martina; Wilbers, Jens – International Journal of Science Education, 2022
Designing and interpreting controlled experiments are important inquiry skills addressed in many current science curricula. The relevant skills associated with the design and interpretation of controlled experiments are summarised under the term control-of-variables strategy (CVS). Research on elementary school students' CVS skills shows that they…

Killian, Benjamin J.; Singletary, Steven – Journal of Chemical Education, 2022
We present a modernization of the undergraduate physical chemistry laboratory experiment for determining the speed of sound in various gases from resonant frequencies in a spherical resonator. The resonator (schematic IR = 7.5 cm) is constructed by 3D printing with eco-friendly poly(lactic acid), a commercially viable alternative to traditional…

Schmidt, Jonas; Huber, Tim; Mu¨ssig, Jo¨rg – Journal of Chemical Education, 2022
The knowledge of the mechanical properties of polymers and other materials is essential for several tasks in the field of materials science, like component design and material development. The tensile test is one method of determining many of the material's most defining mechanical characteristics. However, the teaching of laboratory experiments…

Bozzo, Giacomo; Michelini, Marisa; Bonanno, Assunta; Stefanel, Alberto – EURASIA Journal of Mathematics, Science and Technology Education, 2022
We report a research-based proposal on electromagnetic induction within the theoretical framework of the Model of Educational Reconstruction. The proposal is based on a sequence of inquiry-based experimental activities centered on hands-on materials and "Real-Time" quantitative experiments, through which students explore the…
