Simulasi Difraksi Fraunhofer Menggunakan Media Spreadsheet dan GNU Octave Sebagai Alternatif Pembelajaran dimasa Pandemi

The title of this paper is Fraunhofer diffraction simulation using spreadsheet and GNU octave media as an alternative for learning during the pandemic. This paper aims to present an alternative to distance learning during the COVID-19 pandemic by using simulations using spreadsheets and GNU Octave media. Optical practicum in physics laboratories can not be done during pandemics. So the solution that can be offered is to use simulations on optical subjects of diffraction material. In the simulation making activities students can learn and explore about the phenomenon of diffraction. Simulations using the equations used in the research of Zhang et al. in 2013. This simulation is used to visualize the effect of variations in different parameters such as wavelengths and gap widths in Fraunhofer diffraction patterns. This paper has successfully simulated Fraunhofer's diffraction using spreadsheets as well as GNU Octave. This distance learning allows students to develop fraunhofer computational computational skills and conceptual understanding of diffraction

Interference and diffraction experiment using 3D printing and Arduino

Here, we present a 3D printed experimental apparatus that students can use to acquire interference and diffraction quantitative data from light passing through a single or double-slit experiment. We built a linear screw stage with a multiturn potentiometer connected to its leadscrew as a position sensor. Using an Arduino, we collected light intensity data (from a photodiode mounted in the linear stage) as a function of position. The apparatus is a low-cost and compact alternative with data acquisition to optics physics laboratories.

Formation Of Skills To Visualize Of Future Physics Teacher: Results Of The Pedagogical Experiment

It is relevant for teachers of science to get visualization skills for explaining abstract concepts, showing the logic of processes, and explaining the natural phenomena at the micro and macro levels. For research conducting, authors used theoretical and empirical methods such as analysis of specialized for physics visualization software; survey for determining the needs of physics teachers; analysis of the curricula content for the training of future physics teachers; performing of the pedagogical experiment to determine the effectiveness of the developed model, statistical evaluation is provided by using Student's criterion. The developed model of visualization skills formation of future physics teachers is based on cognitive-visual approaches and provides the modernization of the content of teachers’ training by including a special course. The analysis of software that supports the teaching of physics makes it possible to divide it into three classes: virtual and digital physics laboratories, mathematical and simulation software, office applications with Smart-Art-objects, and animation software. Analysis of the visualization studying material needs of physics teachers, based on a survey, showed the priority of skills in the office suite programs and skills of creating simulation models (static and dynamic). The introduction of a model of visualization skills formation of future physics teachers ensures the achievement of the goal. Further research is directed to the study of the problem of forming future science teachers' skills to use augmented reality in the educational process.
