I use Zoom as a means of online video interaction with students, and the platfotrm Moodle is obligatory in our university for uploading the materails for the disciplines. It's very convenient to update the tasks here. Sometimes I also ask the stidents (especially foreign) to open the presentation in Moodle during the lecture or to write some reaction for my lectures - to get the answer from everybody at once, not only of the most active listeners.
