Secondary school students are the members of gen Z, while their teachers mostly belong to gen X. Due to multitasking in virtual space, dotcom kids' attention, work memory, and brain activity are changing. Their vision of the future, attitude, and priorities are entirely different from those of earlier generations. The children of gen Z question and reject traditional authority; however, they are creative and innovative. In contrast to this, both the knowledge, the attitude, and the value system of their teachers are significantly different from those of the net generation. The purpose of the research was to map adolescents' opinions about generation stereotypes as well as what their teachers think about them--according to the students. The anonymous digital questionnaire was spread in social media; adolescents assessed frequently mentioned statements about gen Z. According to the results, it can be claimed that there are some stereotypes, especially about the usage of digital tools and lasting concentration, which were proved to be true by adolescents. However, youngsters rejected stereotypes referring to the instability of their future perspective, behaviour on the sites of social media, and the quality of relationships. On the other hand, they believe that their teachers' opinion about them is different in many ways, such as in online communication, emotional attitudes, and digital safety.
