The research aim of the study is to verify the effectiveness of educational videos in the educational process. Videos are a popular form of leisure time for teenagers. In this context, videos could be considered an effective school tool. Research shows that educational videos help to create an engram, but also to social overlap, where students interact more thanks to videos submitted by teachers. The research is focused on finding out information about the use of educational videos by high school students aged 15 to 19 in the Czech Republic and Slovakia. We are interested in the quality of their executive functions, motivation, classroom climate and the benefit of respondents in relation to the use of educational videos.
