The introduction of distance learning in Ukrainian schools during quarantine due to the COVID-19 pandemic has updated the study of the peculiarities of the use of different types of electronic educational resources by teachers to ensure quality distance learning. The online survey of 576 teachers in March–May 2020 determined that the introduction of quarantine due to the COVID-19 pandemic motivated 12% of the surveyed teachers to start using electronic educational resources to provide distance learning for students during the lockdown. The analysis of electronic educational resources recommended by the Ministry of Education and Science of Ukraine for use in all schools of Ukraine made it possible to identify areas of educational activity that are insufficiently provided with electronic textbooks and electronic training manuals that have passed the state examination. The results showed that in 2016–2019, electronic textbooks were developed only in some subjects of the 1st, 2nd grades of primary school and 5th, 6th grades of middle school. Among the problems that reduce the effectiveness of distance learning in Ukrainian schools, teachers called the lack of a single portal (platform) with col-lections of quality electronic educational resources in various subjects for educational institutions, insufficient number of quality electronic educational resources and a lack of digital skills. The effective ways to overcome these problems can be: 1) creation of a state register of open electronic educational resources and the development of criteria for their quality; 2) launch of the National educational electronic platform, which will host electronic educational resources recommended by the Ministry of Education and Science of Ukraine; 3) development of open online courses to increase the level of teachers’ digital competence.
