DCBLP, digital systems, e-learning, Packet Tracer, students' opinions

The article presents knowledge about the modified e-learning on-line synchro- nous teaching of digital systems, which took place in the period of widespread closure of schools during almost the entire school year 2020/2021 at a sec- ondary school with an IT focus. The importance of teaching digital systems in computer science and the integration of teaching into available lessons is briefly clarified. Furthermore, the content of teaching is presented, including its modification by elements of programming by DCBLP discourse and links to existing knowledge about this use from previous years. The subject of research interest will be the specific effects of changes on students’ opinions regarding the content of the subject. For this purpose, a qualitative investigation based on the design of the grounded theory will be used. The work brings partial knowledge that can serve as additional material for the determination of other research questions, hypotheses and identification of potential problems in teaching. The results show the pupils’ interest in the digital systems enriched by the programming discourse reveals the possible perception of a long time distance learning in this area.
