Determination of conceptual understanding levels related to optics concepts: The case of opticianry
(Ismail Sahin, 2020) Özdemir, Erhan; Coramik,M.; Ürek,H.; Müzik / Music
Physics is directly related to various professions since it is a fundamental science. Opticianry is one of such physics related professions. In this study, it was aimed to determine the conceptual understanding levels of opticians related to the concepts of light and optics which are directly related to their professions. In the study, which was conducted via mixed method, the participants were determined with the convenient sampling method. A total of 203 opticians attended the study. Data were collected with the help of Light and Optics Conceptual Evaluation Test in addition to the Open-Ended Questions and Concept Cartoons selected from the literature. As a result of the study, it was reached that the conceptual understanding levels of opticians were low with several misconceptions and insufficiencies related to the light and optics concepts. In the light of the findings, the importance of physics education for opticianry was implied. © 2020 International Journal of Education in Mathematics, Science and Technology. All rights reserved.

Examination of prisms via spectacle lenses
(Institute of Physics Publishing, 2019) Özdemir, Erhan; Coramik,M.; Ürek,H.; Müzik / Music
Optics is one of the subject areas in which students have difficulty learning. Establishing the right connections between the concepts of optics and daily life supports the learning of the concepts of optics. In addition, this connection increases the students' motivation to learn optical issues. In this study, three activities related to prisms were performed by using spectacles to increase the connection between the subject of daily life and prisms. These activities have been proposed as real-life activities such as binoculars and a submarine periscope that can be used in the teaching of prisms. © 2019 IOP Publishing Ltd.

Reasons of student difficulties with right-hand rules in electromagnetism
(Scientia Socialis Ltd, 2018) Özdemir, Erhan; Coramik,M.; Müzik / Music
In electromagnetism, to determine the direction of the electromagnetic force and magnetic field, the right-hand rule (RHR) is used. Previous researches show that students have difficulty in applying the RHR. This research is aimed to find out the factors which make it difficult for the students to apply the RHR. To achieve this, qualitative case study design is used and 270 students who took Basic Physics II course at university participated. The Right-Hand Rule-Diagnostic Test (RHR-DT) and the unstructured interview were used as data collection tools. In the analysis of the data, firstly, the right-hand types used by the students were determined. Then the right-hand types used by the students in the solution of each task are presented. After that, eight of these students were interviewed about their RHR-DT answers and those interviews were video recorded. Video recordings are divided into three categories according to the level of students: upper, middle and lower. According to the results of this research, it can be said that the conceptual understanding of electromagnetism, the vector algebra and spatial cognition effect the usage of the RHR. In the light of research results, suggestions were made for the teaching of RHR to physics teachers. © 2018, Scientia Socialis Ltd. All rights reserved.
