Online Learning of Basics of Graph Theory

As a result of COVID-19 pandemic, the methods of teaching at Slovak universities have significantly changed. Before 2019, majority of subjects was taught by face-to-face instruction. Despite positive experience with utilization of modern technologies in education, only a little number of subjects was taught bye-learning or blended learning. In the paper, we summarize our experience with teaching the subject Basics of Graph Theory. In the winter term of the academic year 2021/2022, due to restrictions caused by COVID-19, full-time students had to be taught by a combination of pre-recorded video lessons, synchronous online lessons, and e-learning course, while part-time students were taught only by video lessons and e-learning course. A comparison of students' results in the final test reveals that online learning is a suitable method to teach Basics of Graph Theory, as there is no significant difference compared to the results of the students taught by blended learning two years ago. Further, this method is equally suitable for both full-time and part-time students, since there is no significant gap in the level of their knowledge. Moreover, answers of students in a questionnaire reveal other benefits of this method.
