Over the last five years, the possibilities and implementation of digital technologies in teaching have been strengthened in the Czech Republic. As part of the support of digital literacy, Czech education is undergoing a process of increasing the digital competencies of teachers and pupils in primary and secondary schools. The term "digital literacy" means a set of digital competencies (knowledge, skills, attitudes, values) that an individual needs to safely, confidently, critically and creatively use digital technologies at work, learning, leisure activities and participation in society. Their basic characteristic is the application/use of digital technologies in various activities, in solving various problems. This results in their variability over time, depending on changes of the way and extent of the use of digital technologies in society and in human life. During the COVID-19 pandemic, a number of teachers decided to conduct their teaching online. Among other things, the tasks and their fulfillment and control were given to the pupils electronically. The goals of the expected results of digital literacy were met very quickly and more than before. Particularly interaction through digital technologies, sharing and collaborating through digital technologies, acquisition of data, information and content from digital sources, creation of new digital content, appropriately chosen message format. Our contribution in the form of a research probe among elementary school teachers in two regions verified their rapid development, thanks to the closure of schools and the interruption of regular teaching.
