Ioannis Vlachos; Georgios Stylos; Konstantinos T. Kotsis – European Journal of Science and Mathematics Education, 2024
The physics' subject aims to provide the student with a broad understanding of the physical phenomena that occur around them every day and introduce them to the scientific search. The use of experiments in the teaching of the subject contributes to the understanding of these phenomena, the development of skills and critical thinking and has many…

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…

Chiang, Chun-Ming; Ma, Shih-Hsin; Lin, Shou-Tai; Hsu, Wel-Hung; Huang, Pin-Jui – Physics Teacher, 2022
The wave nature of light has been widely demonstrated in a double-slit experiment, which has played a special role in physics teaching. When monochromatic light passes through the double-slit sheet, the diffraction and interference fringes can be observed in the far-field regime. The interference of light causes the beams passing through the two…

Muammer Çalik; Neslhan Ültay; Hasan Bag; Alipasa Ayas – Chemistry Education Research and Practice, 2024
The purpose of this study is to "meta"-analytically evaluate research that used chemical bonding-based interventions to improve academic performance. Through "meta"-analysis, the present study used several keyword patterns (e.g., chemical bonding, experimental, chemistry education, science education) via relevant databases…

Zvart Ajoyan; Christopher Copeman; Hudson A. Bicalho; Jean-Louis Do; Tiffany Te; Jennifer Romero; Ashlee J. Howarth – Journal of Chemical Education, 2023
Metal-organic frameworks (MOFs) are a class of porous materials that are often crystalline with high surface area and structural tunability. In this laboratory experiment designed for inorganic chemistry students at the undergraduate level, students complete a two-step experiment where they will first (i) synthesize two isostructural…

Miaomiao Lu; Yidan Jing; Tai Feng; Xiaomin Zhang – Journal of Chemical Education, 2024
A comprehensive teaching experiment plan tailored forthird-yearundergraduates has been developed. Initially, instructors synthesize(E)-2-(4-((4-(2-hydroxyethoxy)-3-methylphenyl)­diazenyl)­phenoxy)-ethan-1-ol­(M-Azo-2)monomer as part of the preclass preparation. Subsequently, studentsperform an acylation reaction experiment to prepare an…

Cross, Rod – Physics Education, 2021
A standard problem for physics students is to calculate or measure the acceleration of an object down an inclined plane. Additional information can be obtained by measuring the angular acceleration as well as the linear acceleration. An experiment is described where a billiard ball was filmed as it rolled down an inclined plane at different…

Mariana Hamer; Micaela Hamer; Miguel J. Vago; M. Florencia Leal Denis – Journal of Chemical Education, 2024
In analytical chemistry, discussing different method sand techniques of analysis is essential to promote critical thinking and reasoning. Analytical courses in the chemist, pharmacist, and biochemist curricula represent the opportunity to study concepts such as experimental design, sampling, development, and optimization of protocols, data…

Titration is an important experimental skill that every chemistry educator and learner must master. Titration is often the method of choice in the science laboratory courses in secondary and postsecondary schools. During acid-base titration, chemistry learners are always told about salt formation. However, a practical visualization of the salt…

Ronghui Que; Hongbo Wu; Yalan Zhao; Shasha Han; Min Han; Yan-Lin Xiong; Shanheng Ma; Houxiong Wang – Journal of Chemical Education, 2023
The classic silver mirror reaction at room temperature in textbooks usually used glucose to react with silver nitrate and ammonium nitrate with the presence of caustic alkalis. But the aldehydes such as acetaldehyde and propionaldehyde were difficult to react under the same condition. In this paper, Na[subscript 2]CO[subscript 3] was used to…

Pašic, Selim; Popara, Nato – Physics Education, 2022
We present a novel method for demonstrating the physical principles of ultrasound imaging at a level suitable for educational programmes up to the university level, using a simple mechanical model that is very inexpensive and accessible to a broad variety of educational institutions. The method revolves around the use of one or two steel springs…

Amabile, Alessandro; Annunziata, Annarita; Artiano, Giancarlo; Balzano, Emilio – Education Sciences, 2022
Physics preparation for primary school teachers has received attention only in recent decades. Research on science education provides useful guidelines, often disregarded. Several interrelated research questions must be addressed by field research, namely, (a) which physics subjects to teach in primary school and its relationships with other…

Adil Hamamous; Nadia Benjelloun – Journal of Learning for Development, 2025
CAEx (Computer-Assisted Experimentation) enables real-time experiments to be carried out using a computer; it includes data acquisition and sensor systems, as well as real-time measurement of numerous physical properties. The use of computer-assisted experimentation in the teaching of physics and chemistry in Moroccan secondary schools underwent…
