Distant learning in the Institute of Medicine during the COVID-19 pandemic
... COVID 19 pandemic. In total, 73 students of the 6th year of the medical institute took part in an online training. Instead of three levels of teaching, typical for the “Pain management” course, two were left, i. e., “Theoretical knowledge” and simulation online training “The Interview”. In the end of the course the students were to take an anonymous questionnaire to meet their achievement needs. The research has proved that the online teaching can be viewed as an alternative multifunctional ...
