Educational experiments, demonstrations, and laboratory works are the basis for the study of the natural sciences. The drastic restriction of lessons in a real physics laboratory in 2020 - 2021 clearly demonstrated their negative effect on the quality of education. In terms of distance and blended learning, video analysis of real experiments, processes, and phenomena is a real competitor to the corresponding digital models. The free software Tracker toolkit allows measuring physical quantities on the basis of video material, processing the received data, and comparing them with mathematical models. Tracker usage expands methods of obtaining and practical application of information, shows how to identify the actions of laws, and, therefore, forms the scientific competency of students. The general rules for creating educational videos suitable for analysis using Tracker are given in the article. There are demonstrated different approaches to creating instructions for laboratory works based on video analysis on the examples of labs such as measuring the acceleration of free fall (mechanics), determining the surface tension of a liquid (molecular physics), the study of the rotational motion of the Sun (astronomy). Reference videos, didactic recommendations, a collection of video problems, and instructions on non-traditional methods of educational experiment adapted for video analysis using Tracker have been created. They are posted in the section “Instrumental digital didactics” of the resource www.stemua.science of the National Center “Junior Academy of Sciences of Ukraine”, which is popular among online users. Video analysis techniques are used for formal and non-formal education of pupils and students in the conditions of COVID-19;this has been verified during the training of educators and distance summer science school (2020). © 2020 Copyright for this paper by its authors.
