“…In angular momentum conservation, the action and reaction torques between the particles in the system are not mentioned much. The fact that the cause-and-effect relationship mentioned in angular momentum conservation is not generally mentioned is not a situation that physics students are accustomed to and may cause misconceptions in students [2,3].…”

This study developed a teaching material that makes the conservation of angular momentum, which students find very difficult, more concrete. The fact that angular momentum is a vector concept, the direction of the vector and the importance of this vector direction in angular momentum conservation are visualized. The teaching material consists of a table mounted on a freely rotating shaft, two electric motors mutually connected to the table, and a speed adjuster circuit used to change the rotation speeds of the motors. When electric motors begin to rotate, the angular momentum of the motors changes. How the angular momentum of the system is preserved thanks to the changing angular momentum of the parts interacting with each other, the directions of the vectors formed, the inertia torque, angular velocity, angular momentum relationship, and the relationship of the parts forming a system with each other have been tried to be explained in detail through the teaching material. When the motors were operated in different directions and speeds, the change in the rotation direction of the table was observed. This observation concretizes that angular momentum and angular momentum conservation are vector concepts. The right-hand rule, which describes the angular momentum vector direction with the material, can be demonstrated to students in practice. Video recordings showing how the teaching material works have been shared with readers.

Several researchers have even integrated some instructional approaches as well.…”

This study aims to deliver a summary of conceptual change research based on scientific production, most rele-vant researchers and countries, co-authorship collaboration, and research foci. A bibliometric analysis of the scientific output in the field of conceptual change was carried out utilizing articles published between 2012 and 2021.A total of 515 articles published in educational psychology, cognitive science and science education jour-nals were extracted from Scopus databases. The main findings reveal that the number of articles on conceptual change during the 2012-2021 period is relatively constant. Co-authorship collaborations predominantly consist of researchers from the same country. In addition, a shift in the research foci was observed. Past studies have been widely carried out across disciplines, such as educational psychology, cognitive science, and pedagogic. Meanwhile, recent research foci have brought up curriculum and curriculum development as important keywords.
