This dissertation has as object of study video lessons, youth, and high school. It is recognized that video classes are audiovisual technological resources in the process of expanding their use by young people associated with the teaching-learning process in high school. Video lessons have been present for decades, but with the arrival of the internet and platforms such as YouTube, the number of new videos, as well as views, skyrocketed. In this research, the video classes studied are classes produced in video format and released on streaming platforms for free. Based on this contact, we question the role of video lessons in education and how they relate to the objectives of high school, from the perspectives of the young people who use them. Therefore, this research has as main objective to understand how video classes are being used by young high school students, analyzing whether they would be resources used in a complementary way, as a replacement for traditional classes, or as producers of knowledge. The aim is to answer the questions: How and why are video classes being used by private school students? What are the preferences and motivations of young students? What is the meaning of high school? The research was carried out with middle-class young students aged between 14 and 18, enrolled in high school in four schools of a high-performance private education network in the ENEM of the city of Rio de Janeiro. A questionnaire with 24 closed questions was applied among 122 young respondents from the 1st to the 3rd year of this network of schools in order to analyze the frequency in the use of video classes and preferences in use. They were also asked about the high school segment and its objectives. In addition, a conversation was held with 12 respondents to the questionnaires to identify what would be the meanings for the school by students in this network of schools and to problematize some results of the questionnaire in relation to motivation in the search for video lessons. As theoretical references, studies in the field of sociology by Dubet, didactics by Candau and Mesquita, studies on youth and school by Carrano and Dayrell, and the field of media education by Pischetola, Burguess and Green were adopted. From the data produced, there is a massive visualization of video classes and a diversity of motivations and preferences in the use of these resources. The results pointed to the perception of young people about a strong pressure for results and the intensity of study as the main justification for the use of individual studies through video classes, with the good result in the entrance exam and the preparation for internal tests of the school as drivers of the process teaching-learning. In addition, when characterizing a good video lesson, young people highlight the appreciation of the characteristics of objectivity, synthesis, and speed. Students of this generation bring the need for a faster and more dynamic education, but they also called for interaction, an aspect not very present in video classes, which led to characterizing them as complementary to face-to-face teaching, in which the relational dimension is prioritized. Students identified high school as a stage of gaining maturity and excessive pressure for results. They propose changes, such as the introduction of disciplines such as Financial Education and Life Projects, in addition to possible changes in the current entrance exam model. The great demand for vacancies in higher education is characteristic of the network of schools analyzed and of the social class to which these students belong. The entrance exam ends up being the main objective and is shown as a way to maintain social prestige.
