Blizak, Djanette – Asia-Pacific Forum on Science Learning and Teaching, 2017
This study investigates the effect of using the history of science in teaching geometrical optics on the motivation and conceptual understanding of first year university students. For this purpose, 54 students were randomly selected, then divided into two groups: the experimental group was taught by using history of science before traditional…

Ganci, S. – Physics Education, 2018
A surprising phenomenology from a traditional demonstration experiment in Geometrical Optics reveals here an interesting matter of discussion and analysis. Hence, the main focus of this paper is to observe and discuss such an innovative phenomenology.

Maurício, Paulo; Valente, Bianor; Chagas, Isabel – International Journal of Science and Mathematics Education, 2017
The concepts and instruments required for the teaching and learning of geometric optics are introduced in the didactic process without a proper didactic transposition. This claim is secured by the ample evidence of both wide- and deep-rooted alternative concepts on the topic. Didactic transposition is a theory that comes from a reflection on the…

Tural, Güner – Asia-Pacific Forum on Science Learning and Teaching, 2015
Geometric optics is one of the difficult topics for students within physics discipline. Students learn better via student-centered active learning environments than the teacher-centered learning environments. So this study aimed to present a guide for middle school teachers to teach lenses in geometric optics via active learning environment…

Kaur, Gurjeet – Contemporary Education Dialogue, 2017
Despite its familiarity and the fact that it becomes a formal area of study in early upper primary grades, optics remains a cognitive challenge for young as well as advanced learners, not only because much of it is counter-intuitive but also because its conceptual comprehension involves negotiating the vocabulary and graphical symbolism involved…

Wong, Choun Pei; Subramaniam, R. – Physics Education, 2018
The infrared camera is a useful tool in physics education to 'see' in the infrared. In this paper, we describe four simple experiments that focus on phenomena related to heat transfer and optics that are encountered at undergraduate physics level using an infrared camera, and discuss the strengths and limitations of this tool for such purposes.

Isik, Hakan – Physics Education, 2017
This paper describes the formation of a circumzenithal arc for the purpose of teaching light and optics. A circumzenithal arc, an optic formation rarely witnessed by people, is formed in this study using a water-filled cylindrical glass illuminated by sunlight. Sunlight refracted at the top and side surfaces of the glass of water is dispersed into…

Yasuda, Kensei; Kim, Alvin; Cho, Hayley; Timofejev, Timofej; Walecki, Wojciech J.; Klep, James; Edelson, Amy S.; Walecki, Abigail S.; Walecki, Eve S.; Walecki, Peter S. – Physics Teacher, 2016
In his beautiful paper, Hasan Fakhruddin reported observations of mirror-like reflections in the rough surface of a ground glass plate. Similar effects have been recently employed for metrology of the roughness of optical diffusers used in modern light emitting device illumination systems. We report the observations of specular reflection in…

Mešic, Vanes; Hajder, Erna; Neumann, Knut; Erceg, Nataša – Physical Review Physics Education Research, 2016
Research has shown that students have tremendous difficulties developing a qualitative understanding of wave optics, at all educational levels. In this study, we investigate how three different approaches to visualizing light waves affect students' understanding of wave optics. In the first, the conventional, approach light waves are represented…

Ribeiro, Jair Lúcio Prados – Physics Teacher, 2018
We only became aware of the existence of bed prism spectacles when a student brought them to the classroom and asked us about how they work. The device proved to be a fertile source of curiosity among the students, and, to be properly understood, it required us to develop a comparison between reflection in a typical mirror and total internal…

Ivanov, Dragia; Nikolov, Stefan – Physics Education, 2015
In this paper we consider the main properties of cylindrical lenses and propose several demonstrational experiments that can be performed with them. Specifically we use simple glasses full of water to demonstrate some basic geometrical optics principles and phenomena. We also present some less standard experiments that can be performed with such…

Kesonen, Mikko Henri Petteri; Asikainen, Mervi Anita; Hirvonen, Pekka Emil – EURASIA Journal of Mathematics, Science & Technology Education, 2017
In the present article, the context-dependency of student reasoning is studied in a context of optics. We investigated introductory students' explanations about the behavior of light when different light sources, namely a small light bulb and a laser, were used in otherwise identical task assignments. The data was gathered with the aid of pretest…

Dulmes, Steven; Kellerhals, William – Community College Journal of Research and Practice, 2017
The College of Lake County Regional Photonics Initiative project was motivated in part by the hiring of out-of-state technicians for local Photonics industry positions. Fifteen high paying employment opportunities during the recent recession could not be filled from the locally available workforce. Research on the current demand and future growth…

Moore, Pam – Tech Directions, 2012
Many of the advances in telecommunications and medicine are due to laser and fiber-optic technology. This technology has led to devices that provide faster and richer communication, advanced surgeries, and faster healing times, as well as amazing robotics for manufacturing. But, as with all equipment, someone has to install and maintain it. That…

Tech Directions, 2012
Fiber-optic communication is a method of transmitting information from one place to another by sending pulses of light through an optical fiber that is roughly the diameter of a human hair. The light forms an electromagnetic carrier wave that is modulated to carry information. Each optical fiber is capable of carrying an enormous amount of…
