Full screen video call, suitable for first meeting, getting acquainted. Format for discussing lesson conditions or checking student knowledge level. You can display your student's image on full screen to conduct a quiz on covered material. The student won't be able to peek at the Whiteboard, and you can understand how well the covered material was absorbed.
Video call suitable for parallel work on the Whiteboard, with Study Guides. Suitable when active work is being done on the Whiteboard, and you need to see verbal and non-verbal student reaction to the material. Student actions are visible on the Whiteboard, and their interest or "disinterest" can be seen through video.
Not much and enough to see that the student didn't fall asleep during the lesson and is still continuing to write down material after you. In this video call format you can occupy all space on the Whiteboard with educational material.
Not everyone needs video in lessons. For this there is a format without video. This way you can work on the Whiteboard, exchange links in chat, and have great dialogue on the platform. You can turn audio on and off at any moment during the lesson.
