摘要

在本文中，我们提出了一个替代的物理实验室活动有关的弗劳恩霍夫衍射在远程学习。该活动利用了麻省理工学院开放课件的演示视频、Tracker软件和电子表格。使用在线演示视频，是因为它是在COVID - 19大流行等不利条件下最容易获得的资源。在活动中，学生可以探索多个狭缝的衍射现象。利用Tracker进行光谱分析，研究了狭缝间距和狭缝数对光强的影响。调查之后是通过数学方法和可视化与电子表格的讨论。它将通过对观察的理论解释来丰富学生。这种远程学习活动可以让学生发展他们的科学处理技能，数学和计算思维能力，以及对弗劳恩霍夫衍射的概念理解。

Exploring Fraunhofer diffraction through Tracker and spreadsheet: An alternative lab activity for distance learning

In this paper, we present an alternative for physics laboratory activity related to Fraunhofer diffraction in distance learning. The activity utilizes a demonstration video from MIT Open CourseWare, Tracker software, and spreadsheet. An online demonstration video is used because it is the most accessible resource during undesirable conditions such as COVID 19 pandemic. In the activity, students can explore diffractions phenomena with multiple slits. The effect of slit spacing and slit numbers to the intensity of light is investigated trough spectral analysis with Tracker. The investigation is followed by a discussion through the mathematical approach and visualization with spreadsheets. It will enrich students with a theoretical explanation of the observation. This distance learning activity allows students to develop their science process skills, mathematical and computational thinking skills, and conceptual understanding of Fraunhofer diffraction.

期刊介绍： The Revista Mexicana de Física (Rev. Mex. Fis.) publishes original papers of interest to our readers from the physical science com unity. Language may be English or Spanish, however, given the nature of our readers, English is recommended. Articles are classified as follows: Research. Articles reporting original results in physical science. Instrumentation. Articles reporting original contributions on design and construction of scientific instruments. They should present new instruments and techniques oriented to physical science problems solutions. They must also report measurements performed with the described instrument. Reviews. Critical surveys of specific physical science topics in which recent published information is analyzed and discussed. They should be accessible to physics graduate students and non specialists, and provide valuable bibliography to the specialist. Comments. Short papers (four pages maximum) that assess critically papers by others authors previously published in the Revista Mexicana de Física. A comment should state clearly to which paper it refers.
