Digitalization, a formative factor in the education sector, is in the interest of educational research. It also enables new teaching and learning methods and requires skills from those involved. Media competence is a key competence here. In this context, the optimization of information processes in the Austrian education system is essential and is also an important area of research. Communication with modern communication techniques and cooperation are indispensable here. This dissertation examines the main developmental steps of digitalization in the Austrian education system in a historical longitudinal section as well as their significance for teaching practice. The central areas of digital school development in the Austrian school system are examined and models of digitalization strategies are presented. In addition to comprehensive literature studies, relevant legal norms as well as meta-studies and individual case studies on the research topic were also examined.
