ENDistance education has influenced the organization of education at the level of systems and schools, the change in the specificity of teachers’ activities, the change in pupils’ learning, and, undoubtedly, the attainment of learning outcomes. The aim of this study is to determine what factors have affected pupils’ learning outcomes in the course of distance learning during the COVID-19 pandemic, from the perspective of pupils, pupils’ parents, and teachers. A quantitative study was conducted in order to reveal the impact of distance learning. The positive and negative aspects of distance education became clear. As regards the negative consequences of distance teaching/learning, the results of the study showed that in the teachers’ opinion, the pupils’ learning outcomes generally deteriorated. The positive factors of distance learning influencing the learning process and thus learning outcomes were a comfortable environment, the possibility to use a variety of learning aids available at home, and the possibility to view the lesson records at a time convenient for pupils. Keywords: COVID-19 pandemic; distance learning; factors influencing distance learning. [From the publication]
