The diploma thesis will analyze the initial education of early childhood and preschool teachers and primary school teachers from the aspect of their didactic-methodological preparation in working with modern technology. The educational system has the task of affirming and developing those capacities of the individual that will contribute, in addition to individual growth and development, to the effective development of the entire society. Society of 21st century is characterized by rapid and complex changes that require a high level of flexibility and active participation in modern technology. Our area of interest is the question of whether students (early childhood and preschool teachers and primary school teachers) are properly educated in the field of modern technologies. In the first chapters we will describe important competencies that early childhood and preschool teachers and primary school teachers must have for quality and productive work in general (personal, expert and professional), and then specific competencies for working with modern technologies. The second part of our theoretical consideration is related to the analysis of the basic competencies of students who are being prepared to work with modern technologies. After that, a presentation of all modern technologies (hardware and software) used today for the purpose of education will be made. The central part of the theoretical discussion will relate to the advantages and disadvantages of using technology in educational institutions. At the end of the diploma thesis, review of the research conducted at the Faculty of Teacher Education in Zagreb on students studying in the fields of education and teaching will be made. The research was conducted on the preparation of future early childhood and preschool teachers and primary school teachers to work with modern technologies and their satisfaction with the acquired competencies (knowledge, skills, abilities and values) necessary for successful work with modern technologies. It is concluded on the sample of 114 subjects that most students recognize the courses that prepare them to work with modern technologies, and there are no significant differences between the subsamples defined on the difference of primary teacher education or early childhood and preschool education studies. Although hypotheses that the assessment of competencies for working with modern technologies applied in study practice is positive and that there are no significant differences between future primary school teachers and early childhood and preschool teachers can be accepted, the need for work improvement, especially in the virtual classroom should be emphasized. This problem has become especially relevant and is actualized by the need for distance learning, which has redirected the work of primary school teachers and early childhood and preschool teachers from classrooms to virtual classrooms and from educational groups to virtual groups. Most of the competences for working with modern technologies in the studies are acquired by future teachers through exercises, and future teachers do not differ significantly in the perception of how to acquire competencies for working with modern technologies. Attitudes about modern technologies are positive in the majority of subjects, with the prevailing attitude that modern technology negatively affects the quality of work and differ significantly in some issues among future teachers. In the very first wave of the COVID-19 pandemic, the media focused on ways of organizing distance learning, which until then had no need to place itself in the focus of educational interest. The response of the educational system from preschool to higher education must be directed at adapting to all conditions. This does not mean that the application of digital technology, in the educational process should not be approached with caution, because it is already shown that some of the problems that accompany this otherwise valuable technology are not harmless.
