Today's education is marked by the emergence of new technologies and media that are increasingly used both in life and in teaching. Given that children encounter the media in their earliest childhood, they need to be informed about media content as the media increasingly become an integral part of education. In order to achieve educational processes, it is necessary to integrate contemporary media in a traditional way of learning and teaching. We should strive to take advantage of all that 21st century techology offers and provides. Although this is a great challenge given the lack of media equipment of some schools and weak media competencies of teachers. The aim of the research was to show the importance of modern media in the teaching of the Croatian language and to show the level of education of primary school teachers who encounter the use of modern media in their work on a daily basis. The research was conducted in the form of a survey in which 86 primary school teachers from the territory of the Republic of Croatia participated. The results of the research prove that the use of modern media improves students' educational achievement in understanding teaching topics, but also that teachers lack necessary education regarding the use of media in the education system. The results also show that of the digital tools and platforms offered by Croatian publishers, teachers most often use the "Wordwall" and "e-sphere".
