The main aim of the thesis was to emphasize the importance of information literacy and to explore the stages of information literacy in fourth grade students of Elementary School "Ljudevit Gaj" in Krapina before their entering into higher grades. The theoretical part of this thesis includes the definition of information literacy and the division of information literacy into library, media, computer/information, digital, and visual literacy. The importance of information literacy was especially emphasized. The development of information literacy included curriculums which are related to information literacy, and those are the Informatic Curriculum, the Curriculum of interdisciplinary Subject Information and Communication Technology, and the Curriculum of Croatian language, culture, and media. An important topic in this thesis is online learning implementation in fourth grade during the pandemic. Also, an important topic was the useing of digital educational materials in teaching with the aim of improving and modernizing the teaching process. In this thesis, there is a distinguished influence on informatic literacy on fourth grade students through parents, librarians, and children of their age. The research was conducted at the end of May 2022, and there were 56 fourth graders at Elementary School "Ljudevit Gaj" in Krapina. The hypothesis that students in fourth grade are partially information literate is accepted. The conclusion is that more information literacy should be developed from the earliest school age, and this can only be achieved through the cooperation of information-competent teachers and parents. The influence of peers is big, and there is a need to pay more attention to monitoring how children spend their time virtually today. The role of today’s education is to create informationally responsible members of the community.
