In 1849, Hippolyte Fizeau determined the speed of light in a famous experiment. The idea was to measure the time taken for a pulse of light to travel between an intense light source and a mirror about 8 km away. A rotating cogwheel with 720 notches, that could be rotated at a variable speed, was used to chop the light beam and determine the flight…

This article deals with an exploration of a double superior mirage obtained in laboratory conditions and its contribution to the deep understanding of light events in specialized schools. It was revealed that an explanation of the formation process of a double superior mirage plays a key role in the adoption of knowledge on reflection and…

The purpose of this paper is to present and discuss an alternative solution to an experimental problem given to high school students in the XXII Ibero-American Physics Olympiad held by Colombia this year. From the measurements of electric current and potential difference across a small tungsten filament lamp students should find the dimensions of…

Students are introduced to the term wavelength in optics at school level. In this paper, we present an inexpensive and simple method to measure the wavelength of the light of a light emitting diode using a light depending resistor. This experimental set-up is developed at Science Laboratory, Nehru Planetarium (Mumbai), India. It is useful as an…

The purpose of this study is to investigate the effect of teaching through a virtual laboratory prepared using simulations teaching materials and that are based on constructivist thought about geometrical optics upon the students' academic success and their attitudes towards physics. Quasi-experimental pretest and posttest control groups was used…

The Arduino board and its communication with several sensors are becoming more and more popular in the physical science community. They offer inspiring possibilities for learning different physical concepts. In this article, we focused on creating a very practical educational system for experimenting with diffraction of laser light and graphically…

The pandemic triggered by the SARS-CoV-2 virus has produced worldwide interruptions of face-to-face teaching activity in both schools and universities. In Italy, the quarantine began in the second half of February 2020 and lasted for all the second semester of lectures. The University of Bologna, where all the authors of the present article are…

Contribution: Prior studies indicate that students experimenting with characterization of optical planar waveguides use expensive ready-made prism couplers without clear understanding about construction of the entire optical measurement system. This paper presents a cost-effective modified bright-mode prism coupler that helps students learn…

This research aimed to design an instructional module to teach light diffraction by a grating to secondary students applying a science, technology, engineering, and mathematics (STEM)-integrated approach. Based on this approach, instructional management integrated the disciplines of physics and mathematics with engineering design process…

Nationally and internationally there have been calls for a focus on STEM (science, technology, engineering and mathematics) teaching and learning in schools to prepare students for the many future careers in the STEM fields. One way to do this is through engineering activities that provide opportunities for integrating STEM to solve problems using…

Laboratory activity is closely related and yet is essential in the process of science teaching-learning. The hands-on laboratory experiment is the one normally used in school. Particularly with the state of online schooling, it is quite challenging to perform a hands-on laboratory activity. The combination of inquiry-based learning with virtual…

This research aims to investigate the effect of guided inquiry laboratory activity with video embedded on students' understanding and students' motivation in learning lights and optics topic. The method used in this research was pre-experiment. The sampling technique used in this research was convenience sampling, and the samples were taken from…

The aim of this study was to determine the effect of inquiry-based laboratory activities on the students' understanding of the nature of science (NOS) in learning lights and optics topic. The method used in this research is quasi experiment. Sampling technique using random sampling to class and the samples were taken from grade 8 in one of junior…

Contribution: There are many on-line resources available to learn about optics and photonics, but no assessment tools exist to evaluate the learning achievements. This paper presents an assessment framework whose validity has been proven on a course with over 70 engineering students. Background: There is evidence that on-line resources complement…

In this paper, we present the design and the results of a comparative study that evaluated the success of a transfer of an online-teaching resource between two universities, one in Germany and one in the USA. The teaching resource is an online physics lab that has been used in the physics education of medical students in Germany since 2003. The…
