Videos of physics experiments. A supplementary educational tool for students and teachers

TL;DR

This paper presents a collection of educational physics videos designed to help students measure and analyze physical data, enhancing physics teaching and lab experiences, especially when equipment or time is limited.

Contribution

It introduces a new set of physics experiment videos that guide data measurement and analysis, supplementing traditional teaching methods.

Findings

Students prefer videos for pre-lab preparation.

Videos assist in understanding experimental procedures.

Positive student assessment of the video tool.

Abstract

The educational use of video and multimedia is increasing rapidly in secondary and higher education across all disciplines. Videos for physics education can be found in many universities and other educational institutions websites all over the world. In the area of experimental physics, the available videos demonstrate mainly physical phenomena or physics experiments and only few of them allow for the quantitative estimation of physical parameters. In this work, we present characteristic videos of an ongoing project aiming at the development of a collection of educational videos that guide students to measure data and to analyze them in order to calculate physical quantities. These videos can be used for physics teaching, as a demonstration, as a supplementary educational tool for the students pre lab preparation and also in the physics lab, if the necessary equipment is not available or in case of time consuming measurements. The pilot use of a video related to the measurement of the lead attenuation coefficient in the lab is presented accompanied by the student assessment. The students favor the use of video mainly as a supplementary tool for their pre lab preparation and not as a substitute of the real experiment.
